Dear helpRs
Does anyone have an elegant way of doing the following:
For a given numeric vector, e.g. vec <- c(3,2,6,4,7)
Create a series of vectors where all but 1 of the values are replaced by
0's, e.g.
vec.a <- c(3,0,0,0,0)
vec.b <- c(0,2,0,0,0)
vec.c <- c(0,0,6,0,0)
vec.d <- c(0,0,0,4,0)
vec.e <- c(0,0,0,0,7)
I have looked at `replace', but can't think of a way of making it produce
the 5 lines above without a for loop.
I would also like to assign the names automatically. I can create them
easily using paste, but how does one get R to treat the resulting
character strings as object names to which values can be assigned?
Thanks!
Karen
