Hi:
On the off chance that your 9860 explanatory variables do not completely
take up the 'non-y'
part of your data frame, you can always write a formula string to pass to
the model
function. For example,
form <- paste('y ~ ', paste('x', 1:10, sep = '', collapse = ' + '))
> form
[1] "y ~ x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10"
m <- lm(form, data = df)
HTH,
Dennis
