[R] How to remove 'NA's?

[Erik Iverson]

Well, how about the nomatch argument to the match function, see ?match . The nomatch argument is NA by default.

Hi,

> match(c(3,4), c(3,2,1))
[1]  1 NA

The above result has 'NA' in. Is there a way to make 'match' does not
produce any 'NA's?

Regards,
Peng
