Hi
-----Original Message----- From: r-help-bounces at r-project.org [mailto:r-help-bounces at r- project.org] On Behalf Of Niklas Fischer Sent: Thursday, September 20, 2012 11:13 PM To: r-help at r-project.org Subject: [R] creating new variable Dear R-helper I have a data which is about stregth of personal relationship There are two important variable , first one shows if there is a relationship, second one how strong it is. I'd like to create dummy variable which is a combination of these two variables and shows strength of personal relationships. The problem is while first input variable is dummy, the second one is five level likert data (1: very weak, 5 very strong) I would create new variable including three categories (weak, moderate, and strong) but I have to create two categories.
Well I am a little lost in your explanation maybe you could show us part of your variables. Anyway if rel is existence of relation
rel<-sample(0:1, 10, replace=T)
and int is intensity of relation
int<-sample(1:5, 10, replace=T)
whole <-int*rel
[1] 2 1 5 2 5 0 4 4 0 2
Gives you 0 where there is no relation and numbers 1:5 showing intensity of relation
change it to factor
whole <-factor(whole)
and chase levels
levels(whole) <-rep(c("weak", "medium", "strong"), each=2)
Regards
Petr
Do you know any way to do so. Regards, Niklas [[alternative HTML version deleted]]
