I have a high dimension linear model: y~ x1 + x2 + ... + x_n. n is very large.
For linear model fit, I wish to use a sequence of covariates, say X1 to X200, without typing every single covariate in the function (my variable names are coded in the pattern of X1, X2, ...). I think all.var or all.names might have worked but I can't figure out how to do it. Please help.
