[R] Error: R for Windows GUI front-end has stopped working

[andrija djurovic]

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.

Here is my session info:
