I would like to be able to extract the names of the variables in a formula that specifies random effects. For example, given: random = ~ 1+year | st_name I'd like to be able to get "year" and "st_name" out of random. Neither terms(random) nor random[2] seems to work. Is there a way to get variable names out?
Thanks in advance! Rebecca ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
