[R] Backslash in paste() function

Hi,

I'm trying to build a vector of latex commands. However, I need the command strings to begin with a backslash "\". I have:

test <- c('foo','bar')

and I need to rebuild the array, encapsulating the text items with latex stuff, like this:

paste("\parbox[b]{3cm}{", test, "}", fill=TRUE)

Actually, cat() prints the string fine if one uses double backslashes. However, I can't save the result from cat() back to a vector. And when I use cat() inside the latex function from the Hmisc package, I only get errors... The (not so) funny thing is that I can use paste() on a few latex commands. So if I needed to make the strings bold, the following works:

paste("\bfseries{", test, "}")

I've read the R FAQ 7.37, but it only deals with cat(). Not paste. Or I just didn't get it :o/

Is there a way to paste() the backslash character?
