You did not specify what you were expecting as output. Here is one way of using 'merge', but I am not sure if this is what you were after: > r1<-c(1,1,2,3) > r2<-c(2,1,2,2) > r3<-c(2,1,4,1) > data1<-data.frame(r1,r2) > data2<-data.frame(r1,r3) > data1 r1 r2 1 1 2 2 1 1 3 2 2 4 3 2 > dat

Re: [R] Joining two files

Hi Jim, I did not try merge because I thought it only adds variables instead of cases. Below is what I am trying to do. When I joined data1 and data2, I was was expecting three variables: r1, r2 and r3 with r2 and r3 presenting missing values where they did not exist in the first place. V > r1<-c(

Hello all, I al trying to join (ADD FILES in SPSS) two files using the rbind() function. However, with rbind() R does not behave the same way as SPSS. I mean, it just concatenates the two blocs with no consideration for same variables if these are not in the same position in the two files. Anyone k

Re: [R] error in IF condition with factor evaluation

Hi Edoardo, there is a difference between comparisons and assignments, both semantically as well as in R syntax: "==" vs "=" or "<-", latter being more obvious an assignment. This is the source of your error. But to change the labels of a factor object, it is easier to do sth like at<-factor(1:5,l
