Subject: [R] Hash Table - Select and Change Data iniside Matrix Using "Between"
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
