Hello-

I am new to R and am trying to use glmpath for LASSO logistic regression. My data set contains 40 observations and a mix of dichotomous, categorical, and continuous potential predictor variables.

I am having a problem with the 'weight = rep(1, n)' argument that relates to an optional vector of weights for observations.

I would like to have the same weight for all 40 observations. However, if I enter 'weight = rep(1, 40)' as part of my code, I get the following error message:

"Error in if (length(weight) != n) { : argument is of length zero".

I would appreciate any help that people can offer and apologize in advance if I have missed an obvious answer.

Kind regards,

Bob
