[R] Recoding variable levels in R

[Stuart Leask]

Hi there. When I wished to recode two variables in SPSS, I could use the
command RECODE:

recode VAR1 VAR2 VAR3 etc. (1=0) (2=1) (3,MISSING=SYSMIS) (else=0).

In R, I can 'hand-crank' each variable (using ifelse, or if the data is in a
matrix by logical tests, or no doubt numerous other methods) one variable
and one level at a time, but is there a more general function available?
