Hi, Try: set.seed(634) dat<- data.frame(date=seq(as.Date("2012-11-15"),length.out=10,by="1 day"), value=rnorm(10)) subset(dat,"2012-11-19" < date) # date value #6 2012-11-20 -0.3290021 #7 2012-11-21 0.3106802 #8 2012-11-22 -1.0782814 #9 2012-11-23 -0.1333426 #10 2012-11-24 0.8441754 A.K.
I have a problem with comparing dates. i tried it like "datesub = subset(data, 2012-11-19 < data$date)", but this doesn't work and i don't know why.
