Pulling data into a model
2 messages · Crosby, Jacy R, Luc Villandre
Hi Jacy,
I'll take my chances answering your question.
I'd suggest using the paste() function and then transforming the string
into a formula object:
my.formula =
as.formula(paste("y~x1+x2+",paste(colnames(REG)[2:num],collapse="+"),
sep= "")) ;
aov(my.formula,data=REG) ;
The first line creates a string that then becomes your formula statement.
Is this what you're looking for?
Cheers,
Luc

I'm creating an ANOVA model. Is there a way to pull in consecutive columns of variables for the test? Example: aov1<-aov(y~x1+x2+REG[,2:num], data=REG) I'm not looking for interaction effects, I just want to create a model for the first few columns of variables (exact number and names will vary) and a few other predetermined variables (in the example I named them x1 and x2). Thanks in advance. - Jacy [[alternative HTML version deleted]]
