Get variable names from results of lm()

I think the easiest that comes to mind is simply

names(coef(myMod))

But did you look at myMod$terms[[3]] ? That seems to be the RHS of the
formula input (in the few cases I tried)

Best,

It depends a bit on just what the OP wants. In case one of the
predictors is a factor, say 'grp' with levels c('A','B','C'), the
coefs will include the names 'grpB' and 'grpC'. If only the
name 'grp' is wanted, one could use myMod$terms[[3]] or
equivalently formula(myMod)[[3]]. It might be instructive for the
OP to look at as.list(formula(myMod)). formula(myMod) is a
language object which has the tilde operator operate on
the LHS (component 2) and the RHS (component 3).

Stumbling around I found I could get the response variable name from

myMod$terms[[2]]

but using

myMod$terms[[1 ]]

gives a tilda.

I found the names buried in other places in the model object and in the
summary of the model, but is there a more direct way, similar to using
coef(myMod) to get the coefficients?
