Hi, I have a query about the following:
CONTEXT: if we define: eq <- y ~ x1 + x2 then is.language(eq) returns true. this works perfectly with commands such as lm(eq,data=my.data) THE PROBLEM: Now I have a big data set with about 2000 independent variables. So I tried to automate this. I can pick off the names of the variables and insert a plus in between them and get a string. Thus I have eq<- y ~ " x1 + x2 + ... +x2000" or eq<-"y ~ " x1 + x2 + ... +x2000" from either case how can I typecast eq into a langugae object and get the lm command to work ? Does anyone have any suggestions? thanks Arnab. ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
