Hi,
I have a few lines of code that will remove outliers for a regression test
based on the studentized residuals being above or below 3, -3. I have to do
this multiple times and have attempted to create a function to lessen the

I run into trouble with
Hi,
x and y are being picked up from your global environment, not from the
x and y in dataset. Here is a version that seems to work:
rm.outliers = function(dataset,var1, var2) {
dataset$varpredicted = predict(lm(as.formula(paste(var1, var2,
sep= ~ )), data=dataset))
dataset$varstdres =
First off, thank you for the help with the global environment.
I have however attempted to run the code and am now presented with a new
error which is
Error in formula.default(eval(parse(text = x)[[1L]])) : invalid formula
and am not sure what to make of it. I have tried a few different work
