It's easy to run a linear regression on a simple model without an

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.)
