It would behoove you to read some introductory materials -- use
help.start() to get be provided with the standard "An Introduction to
R."
More generally, the help system can be accessed by typing help("name")
or, as a shortcut, ?name. In your case, help("&") would lead to the
correct answer.

Hi Michel,
In this function, I want to apply âORâ operator instead of â&â
Condition.
dat[dat$AGE<=40 & da$AGE>=30,"TRUE/FALSE"]<-TRUE
How it is possible ?

Greater than or equal to is simply >= like most languages.
For more complicated questions, simply combine booleans:
E.g., between 5 and 25
with(dat, (AGE < 25) & (AGE > 5))
and so on.

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 --
