Hi,
Try this:
dat1<-data.frame(a,b,c)
dat1[a<=c& b>c,"abc_check"]<-TRUE
> dat1
?? a?? b? c abc_check
1 10 100 50????? TRUE
2 20 200 60????? TRUE
3 30 300 70????? TRUE
#or
dat1<-within(dat1,{abc_check<-ifelse(a<=c & b>c,"TRUE","FALSE")})
?dat1
?? a?? b? c abc_check
1 10 100 50????? TRUE
2 20 200 60????? TRUE
3 30 300 70????? TRUE
