[R] optimizing lm with multiple very similar RHSs

Dear list, I would like to do something like: # Simulate some example data tmp <- matrix(rnorm(50), ncol=5) colnames(tmp) <- c("y","x1","x2", "x3", "x4", "x5") # Fit a linear model with random noise added to x5 n times n <- 100 replicate(n, lm(y ~ x1+x2+x3+x4+I(x5+rnorm(nrow(tmp))), data=as.data
