There aren't "empty" values in R..... nor is it likely you have a 
matrix of this form, but perhaps a data frame. 

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))
