Hash Table - Select and Change Data iniside Matrix Using "Between"

I already answered this. Don't double post questions.
Hi,

Here i have been an matrix like this,

*NAME ? ?AGE ? PALCE ? ? ? ? ? ? ? ?TRUE/FALSE*
ABC ? ? ? ? 20 ? ? ?INDIA
XYZ ? ? ? ? 30 ? ? ? FRANCE
PQR ? ? ? ?40 ? ? ? USA
MNO ? ? 30 ? ? ? ?KENIYA
DEF ? ? ? ?25 ? ? ? ?AUSTRALIA
GTY ? ? ? ?34 ? ? ? CANADA
BNH ? ? ?38 ? ? ? ?JAPAN

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= 32*.
Note :- i dont want to use any loop and do. Main intension is avoid loop,bcz
there is a bulk of data.

Final Matrix should be like this
*NAME ? ?AGE ? PALCE ? ? ? ? ? ? ? ?TRUE/FALSE*
ABC ? ? ? ? 20 ? ? ?INDIA
XYZ ? ? ? ? 30 ? ? ? FRANCE
PQR ? ? ? ?40 ? ? ? USA
MNO ? ? 30 ? ? ? ?KENIYA
DEF ? ? ? ?25 ? ? ? ?AUSTRALIA
GTY ? ? ? ?34 ? ? ? CANADA ? ? ? ? ? ? ? ? TRUE
BNH ? ? ?38 ? ? ? ?JAPAN ? ? ? ? ? ? ? ? ? ? TRUE

and finally got 1 solution like this,

If "dat" is the name of your data.frame,
dat[dat$AGE == 30,"TRUE/FALSE"] <- TRUE

But how will use if i want to change to TRUE, *AGE between *30-to-40 ??

Immediate Help Requied
