[External] Concatenation?

... or simply
paste0(c("A","B","C"), c(1,2,3))
[1] "A1" "B2" "C3"

See ?paste for other useful options.

paste(c("A","B","C"), c(1,2,3), sep="")

in your example
paste(site, depth, sep="")

If I have a vector of site abbreviations and a vector of depths in those
water bodies, is there a simple way in R to combine them to make a third
vector?
Examples:

site    depth           desired
MU      0               MU0
MU      1               MU1
MU      2               MU2
MC      0               MC0
MC      1               MC1
MC      2               MC2

The dataset has many more lines than this.  I can see how to do this with
lots of if statements, but does R have magic that can make it happen
easily?  I guess this would be called concatenation.
