This may not be the smoothest way to produce the result, but here is a two-step solution:
first find the formula within the object created by the call to glm(): form <- qq["formula"] or equivalently form <- qq$formula then apply the function all.vars() to the result, and return the first element variables.in.formula <- all.vars(form) variables.in.formula[1] # will be the response variable leffgh wrote: > > for example > glm(a~b+c+d,data=eee)->qq > > Is there a function able to return the name of the response variable? > suppose "ff" is the function satisfying this need, > ff(qq) then "a" (Not the value of a) will be returned. > could you tell me which is the "ff" I am looking for ? > > Thank you very much > > -- View this message in context: http://www.nabble.com/a-very-easy-question%2C-how-to-extract-the-name-of-the-response-variable-tf4796264.html#a13722941 Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
