R: characters
Hmm, it seems that the only difference is the use of "as.data.frame(a)" instead of "a". Hence, the same result can be done with: a <- rbind(c(T, T, F), c(F, F, T)) a[a==F]="" as.data.frame(a) A possible drawback is that the mode changes from logical to character when using a[a==F]="" Instead you could use a[a==F]=NA, but that won't get you blank lines.

you could convert it to a data.frame, i.e., a <- rbind(c(T, T, F), c(F, F, T)) a[!a] <- "" as.data.frame(a) I hope it helps.

hi all assume that i have the following table a=rbind(c(T,T,F),c(F,F,T))
a
[,1] [,2] [,3] [1,] TRUE TRUE FALSE [2,] FALSE FALSE TRUE I would like to change all the FALSE entries to a
blank. how can i
do this? i could simply use a[a==F]="" a but then how would i remove the " " from the
entries.
i know that this should be very easy!!! / allan
