RLangTip
Get an overview of documentation for an installed package: help(package="<package-name>") #rstats

A single index can be used to select from a matrix. For example, X[row(X)==col(X)] is the same as diag(X) #rstats http://t.co/EY1uMfny
Robust function writing tip: use seq_len(N) instead of 1:N (it handles the N<1 case appropriately): http://t.co/mZdDZCJE #rstats
Train support vector machines in R with the "svm" function from the e1071 package: http://t.co/OM5duD90 #rstats
A handy alias (via @hadleywickham) for #rstats to prevent saving or loading workspaces: R --no-save --no-restore-data --quiet
Filter list elems that match a condition: id<-sapply(mylist, function(e) test(e)); mylist[id] # Replace "test" with any T/F expr #rstats
The # character introduces comments in R. Everything after the # character to end-of-line is ignored by the interpreter. #rstats
The "break" statement immediately exits from a "for" or "while" loop: http://t.co/O4xamQqt #rstats
To debug warnings, options(warn=2) converts warnings into errors #rstats
