Suppressing the Intercept in lm() when using a dataframe for the model

It's easy to run a linear regression on a simple model without an intercept just by doing this: lm(y ~ x1 + x2 -1) Is there a similar trick to suppress the intercept when your model is in a large dataframe and you don't want to write out the names of individual columns?
Something along the lines of: lm(y ~ . -1, data=dfrm) But you do need to offer specific examples to get specific answers. (Hence the usual advice to read the Posting Guide.)
