[R] merging 3 data sets at once

[kayj]

Hi All,

I am looking into merging 3 data sets I know how to do that by merging data1
with data2 and then merging the result with data 3. I was wondering if it
can be done all at once so I tried,

M<-merge(data1,data2,data3, by=”ID”)

It does not work!
Any ideas?
