Error: R for Windows GUI front-end has stopped working
...tor(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:

data frame manipulation with zero rows
...lass =
"data.frame")
It is not the usual case, but it can happen. With this df, when I pass the
above mentione line, I get an error :
>PosFut=ddply(futures, c("DESCRIPTION","SETTLEMENT"), summarise, POSITION=
sum(QUANTITY))[,c(1,3,2)]
Error in tapply(1:nrow(data), splitv, list) :
arguments must have same length
How can I avoid this when my df is empty?
Any help is appreciated
