print problem with data frames (PR#698)
Another one from the student computer practicals: it is possible
to create a dataframe that cannot be printed. Thus
> fred <- data.frame(happy=c(TRUE, FALSE, TRUE), sad=7:9)
> tmp <- fred[c(FALSE, FALSE, TRUE, TRUE)] # no error message!
> tmp
Error in as.matrix.data.frame(x) : dim<- length of dims do not match the length of object
> print.default(tmp)
