Re: [R] 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.

Best,

Martin
