[R] Hash Table - Select and Change Data iniside Matrix

[arun]

Hi Antony,

Try this,
da<-read.table(text="NAME    AGE        PLACE    
ABC        20      INDIA
XYZ        30      FRANCE
PQR        40      USA
MNO        30       KENYA
DEF        25        AUSTRALIA", header=TRUE,stringsAsFactors=FALSE)

> da2<-function(x){
 if(x==30)
 TRUE
 else
 FALSE
 }
da3<-sapply(da$AGE,da2)
TRUE_FALSE<-da3
da1<-data.frame(da,TRUE_FALSE)
 da1
  NAME AGE     PLACE TRUE_FALSE
1  ABC  20     INDIA      FALSE
2  XYZ  30    FRANCE       TRUE
3  PQR  40       USA      FALSE
4  MNO  30     KENYA       TRUE
5  DEF  25 AUSTRALIA      FALSE


A.K.
