Hi Jon,  I read your question differently.  Is the answer?  - Rex

?strsplit

x <- "ThisIsaString"
y<- strsplit(x,"")

This gives a list, which you can convert to a vector by unlist(y)

Incidentally, you could have found out about strsplit via R's
help.search("character string") (or similar) or even googling "R
string function" . Please use R's native Help capabilities before
posting to the list.

(I will grant that the unlist()  trick may not be that easy to find).

Also, it's often worthwhile searching the Help archives first. Peter
Dalgaard answered this same question here a day or two ago.

Cheers,
Bert
