R help - Mar 2004 - splitting a character vector

Dear R People:

Suppose I have the following;

xa <- c("There are 5 dogs")

I would like to have a new character vector such that
xb[1] is There
xb[2] is are
xb[3] is 5
xb[4] is dogs

Since the original vector has length 1, substring will not work.

Any suggestions would be MOST welcome!

thanks

Dear Erin,

unlist(strsplit(xa, " ")) should give you what you want; note that you
don't
need c() to define xa in your example.

I hope this helps,
 John
