Not with read.table, if they are really missing. But you can replace them later - see below - and if they are marked you can change what read.table considers to be 'missing'.

NA _is_ an 'empty space', in the sense of a correctly recorded missing value.

If you mean some other kind of empty space - perhaps the string "" - that's not missing, just empty (!).

But with a vector containing NA's, like
(  x <- c(NA, NA, letters[1:5]) )

you can do things like 

x[is.na(x)] <- "Empty Space"

x[is.na(x)] <- ""
