Book Description
Turn your R code into packages that others can easily download and use.

Book Description
Can a lost girl save a found dog? Find out in this unforgettable story about discovering true friendship, finding home, and the possibilities of forgiveness. Hadley is angry about a lot of things: Her mom going to jail. Having to move to another state to live with her older sister, Beth, even though they haven't spoken in five years. Leaving her friends and her school behind. And going blind. But then Hadley meets Lila. Lila is an abandoned dog who spends her days just quietly lying around at the local dog rescue where Beth works. She doesn't listen to directions or play with the other dogs or show any interest in people. So when Lila comes and sits by Hadley (which is hardly anything, but it's more than she's done with others), Beth thinks maybe Hadley can help Lila. She tells Hadley they'll bring Lila home as a foster dog and Hadley can teach her to follow commands, walk on a leash, and be more of a people dog so she's ready to be adopted. Only working with Lila is harder than Hadley thought, and so is the mobility training she starts taking to help with her failing vision. It feels like Lila is too stubborn to train and that learning to use a cane is impossible. But unless Hadley can help Lila, she'll never be adopted into a home. If Hadley could just let go of her anger, she might be able to save Lila ... and herself. New York Times bestselling author Kody Keplinger weaves an unforgettable story about discovering true friendship, finding home, and the possibilities of forgiveness.

Book Description
Who will speak for those who no longer can? When a young woman is found strangled to death and left on a park bench in Santa Rosa, California, Detective Eddie Mahler and his Violent Crime Investigations Team are called to the scene. The crime immediately thrusts Mahler back to two unsolved homicides—young women who were also strangled—at this same location a couple of years earlier. He knows who was responsible, but his inability to find evidence to stop the serial killer has haunted him ever since. Now suffering from chronic migraines that affect his vision, Mahler has secretly lost faith in the investigation process, and must rely more than ever on his team. Its newest member, Eden Somers, is a former FBI analyst whose ability to completely immerse herself in the evidence of a case proves both a gift and a curse. While Eden dives deep into the cold case evidence, the rest of the team chase leads to identify the latest victim, and discover that her death might be the work of a new killer altogether. Now Mahler and his team are fighting on two fronts to discover who stole the very breath from these women, and to stop the killer before he silences another victim. Introducing the Violent Crime Investigations Team, a modern series of hardboiled crime fiction, taking on the very worst of California crime.

Book Description
"The Cavendishes flourished during the high tide of British aristocracy following the revolution of 1688-89, and the case can be made that this aristocracy knew its finest hour when Henry Cavendish gently laid his delicate weights in the pan of his incomparable precision balance. For this it took two generations and two kinds of invention, one in social forms and the other in scientific technique. This biography tells how it came to pass."--BOOK JACKET.
