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
