Hi all. I found one situation, on my OS - Windows 7, where R stops working with reported error R for Windows GUI front-end has stopped working.
Here is the example: library(plyr) DF <- data.frame(x=c(1:3, NA, NA), y=factor(sample(1:3,5,rep=T),levels=1:5)) DF[DF$x<3, ] #this works properly ddply(DF, .(y), nrow, .drop=FALSE) #this causes the problem ddply(DF[DF$x<3, ], .(y), nrow, .drop=FALSE) Sometimes R deals with this without closing a program and with reported error: Error in split_indices(seq_along(splitv), as.integer(splitv), attr(splitv, : INTEGER() can only be applied to a 'integer', not a 'char' but in the most of cases just stops working. Does anyone know if this is happening also with other OS or only with Windows 7.
