svglite 1.0.0

How to Run A Shiny App in the Cloud Using Tutum, Digital Ocean and Docker Containers

Who’s downloading the forecast package?

The github page for the forecast package currently shows the following information Note the downloads figure: 264K/month. I know the package is popular, but that seems crazy. Also, the downloads figure on github only counts the downloads from the RStudio mirror, and ignores downloads from the other 125 mirrors around the world. Here are the

How Could Classification Trees Be So Fast on Categorical Variables?

Because I never took time to look at it carefuly. Consider some simulated dataset, with a logistic regression, > n=1e3 > set.seed(1) > X1=runif(n) > q=quantile(X1,(0:26)/26) > q=0 > X2=cut(X1,q,labels=LETTERS) > p=exp(-.1+qnorm(2*(abs(.5-X1))))/(1+exp(-.1+qnorm(2*(abs(.5-X1))))) > Y=rbinom(n,size=1,p) > df=data.frame(X1=X1,X2=X2,p=p,Y=Y) Here, we use some continuous covariate, except...
