If I have a large dataset (i.e. 500 column variables), how can I run a regression defining a large range of independent variables without explicitly writing the variable names in the code (i.e. lm(y~x1+x2+x3+x4+x5+x6 ... x100) )?
Thanks.

`as.formula(paste0("y~", paste(paste0("x", 1:100), collapse = "+")))` – MichaelChirico Dec 05 '15 at 21:52

In some places a dot will do the trick. `~.` or `y~.` – rbatt Dec 05 '15 at 22:27
