R Graphics Essentials for Great Data Visualization: +200 Practical Examples You Want to Know for Data Science

Data visualization is one of the most important part of data science. Many books and courses present a catalogue of graphics but they don’t teach you which charts to use according to the type of the data. In this book, we start by presenting the key graphic systems and packages available in R, including R base graphs, lattice and ggplot2 plotting systems. Next, we provide more than 200 practical examples to create great graphics for the right data using either the ggplot2 package and extensions or the traditional R graphics.
With this book, you ‘ll learn:
\- How to quickly create beautiful graphics using ggplot2 packages
\- How to properly customize and annotate the plots
\- Type of graphics for visualizing categorical and continuous variables
\- How to add automatically p-values to box plots, bar plots and alternatives
\- How to add marginal density plots and correlation coefficients to scatter plots
\- Key methods for analyzing and visualizing multivariate data
\- R functions and packages for plotting time series data
\- How to combine multiple plots on one page to create production-quality figures. **

Prince Lestat and the Realms of Atlantis

**Anne Rice’s legendary vampire chronicles is soon to be a major TV series**
“In my dreams, I saw a city fall into the sea. I heard the cries of thousands. I saw flames that outshone the lamps of heaven. And all the world was shaken…”
Lestat de Lioncourt is no longer alone.
A strange, otherworldly spirit has resurfaced, taking possession of his body and soul. All-seeing, all-knowing, its voice whispers in his ear, telling the hypnotic tale of Atlantis, the great sea power of ancient times…
Prince Lestat is seduced by the power of this ancient spirit, but is he right to trust it? Why has Lestat, leader of the vampires, been chosen as its bodily host?
And what of Atlantis, the mysterious heaven on earth? Why must the vampires reckon so many millennia later with the terrifying force of this ageless, all-powerful Atalantaya spirit?
It falls to Lestat to discover the truth.
‘There’s little doubt about the paperback that will be selling like hotcakes this month. Anne Rice’s *Vampire Chronicles* saga continues.’ – SFX
‘Linguistically masterful, structurally solid and weaved like a gossamer web of nightwalker excellence. Anne Rice further solidifies her undisputed reputation for penning novels of dark poetry, where Lestat lives and breathes in all his benevolence. Pompous, preening, princely and beyond earthly reproach. For the uninitiated and experienced traveller alike this continuation of *The Vampire Chronicles* makes a mockery of any shared cinematic universe you can name.’ – Flickering Myth
‘Anne Rice’s prose has always been lyrical and poetic, the words ebbing and flowing from page to page, calmly and rhythmically. In this latest edition, she proposes some ethical and spiritual quandaries from both sides of the sets of characters.’ – On: Magazine

Practical Security

Most security professionals don’t have the words “security” or “hacker” in their job title. Instead, as a developer or admin you often have to fit in security alongside your official responsibilities – building and maintaining computer systems. Implement the basics of good security now, and you’ll have a solid foundation if you bring in a dedicated security staff later. Identify the weaknesses in your system, and defend against the attacks most likely to compromise your organization, without needing to become a trained security professional. Computer security is a complex issue. But you don’t have to be an expert in all the esoteric details to prevent many common attacks. Attackers are opportunistic and won’t use a complex attack when a simple one will do. You can get a lot of benefit without too much complexity, by putting systems and processes in place that ensure you aren’t making the obvious mistakes. Secure your systems better, with simple (though not always easy) practices. Plan to patch often to improve your security posture. Identify the most common software vulnerabilities, so you can avoid them when writing software. Discover cryptography – how it works, how easy it is to get wrong, and how to get it right. Configure your Windows computers securely. Defend your organization against phishing attacks with training and technical defenses. Make simple changes to harden your system against attackers. What You Need: You don’t need any particular software to follow along with this book. Examples in the book describe security vulnerabilities and how to look for them. These examples will be more interesting if you have access to a code base you’ve worked on. Similarly, some examples describe network vulnerabilities and how to detect them. These will be more interesting with access to a network you support.

Portal of a Thousand Worlds

**The looming threat of a once-in-a-millennium magical event sends nineteenth-century China into violent chaos in this epic alternate-history fantasy.**
Author of the Seventh Sword series Dave Duncan transports us to Imperial China in an alternate nineteenth century – an Asian epoch not unlike the Boxer Rebellion era – with a spellbinding tale of rebellion, political intrigue, larceny, seduction, shape-shifting, dark magic, and murder. These are troubled years in the Good Land.
Ten centuries have passed since the last time the Portal of a Thousand Worlds opened, bringing chaos, upheaval, and radical change to the then-ruling dynasty, and now the mystical gateway is rumored to be on the verge of opening once more. Only the Firstborn – he who has been reincarnated through countless generations and remembers all he has ever learned – knows what the future holds, but he has been imprisoned for refusing to comply with a repressive imperial government’s wishes.
Now, those hoping to seize the opportunity for wealth and position are hatching sinister plots. And as the cold-hearted dowager empress closely guards a fateful secret, and a rebel army led by a fanatical zealot gathers strength under the Bamboo Banner, the cataclysm approaches. . . .
The recipient of two Aurora Awards and numerous Locus and Endeavour Award nominations, Dave Duncan is an acknowledged master of sword-and-sorcery adventure on par with George R. R. Martin of *Game of Thrones* fame. A sprawling epic with a colorful cast of royals, thieves, prostitutes, gods, warriors, dragons, assassins, merchants, and mages set against the backdrop of a volatile alternate Asia, *Portal of a Thousand Worlds* is a magnificent work of invention from one of the premier fantasists of our day.

Poesie (Classici)

Nella poesia di Federico Garcia Lorca (1898-1936) si avvertono, spesso intrecciate e coesistenti, varie tematiche d’ispirazione e di espressione lirica: la musica e il canto, la sensibilità pittorica e coloristica, la tradizione popolare e quella colta, il surrealismo. In pochi autori la poesia del novecento ha mostrato una capacità così forte, come in Garcia Lorca, nel mitizzare il paesaggio, il sentimento erotico, il luogo comune proposto dal folclore, creando una poetica del tutto unica ed originale.

Si soffermò per un attimo attorno alla sua vagina, obbligandola ad afferrare i suoi capelli e a spingere la sua bocca affamata contro la sua vulva.
Procedendo pian piano, Alec le baciò la vagina. Ogni bacio mandava un brivido nel corpo di Michelle.
Con due dita le accarezzò le labbra esterne, tra i suoi gemiti. Ad ogni passaggio cambiava il modo di premere. Alec spinse la sua bocca nella sua vagina e diede delle forti leccate dall’alto al basso.
Poi con il movimento sinuoso della sua lingua iniziò a far godere Michelle. Le sue labbra diventarono spesse ed il clitoride turgido.

Pale Guardian

During the carnage of World War One, James Asher joins forces with the vampires of Europe to counter an even deadlier threat.

The vampires call them ‘The Others’. Neither living nor dead, the revenants are mindless and unstoppable – and in the carnage of the First World War, governments already running short of men to throw into battle might be very interested in soldiers who don’t ask questions and are hard to kill. Front-line volunteer nurse Lydia Asher is horrified to learn that someone has found a way to control revenants, and is creating them for this purpose.

Back in London, Lydia’s husband, former spy James Asher, is even more appalled to learn that revenants are beginning to show up in England, on the loose. Since revenants devour vampires, the vampires of Europe – most of whom are at the Front, feeding completely unnoticed on the dying – join forces with the Ashers to find the source of the threat before the world is…
