Perhaps this works for you, If "dat" is the name of your data.frame, dat[dat$AGE == 30,"TRUE/FALSE"] <- TRUE Next time do use dput() to give a reproducible example of your data -- if it's very large, just limit it to the first 30 rows or so with dput(head(dats, 30)) Michael On Fri, May 25, 2012 at 9:43 AM, Rantony <[hidden email]> wrote: > Hi, > > Here i have been a matrix like this, > > *NAME AGE PALCE TRUE/FALSE* > ABC 20 INDIA > XYZ 30 FRANCE > PQR 40 USA > MNO 30 KENIYA > DEF 25 AUSTRALIA > > Here,* TRUE/FALSE* Column containing empty values. > > So my requirement what is , need to change all the *TRUE/FALSE *column value > into "*TRUE*" where *AGE = 30*. > Note :- i *dont want* to use* any loop *and do.
