Hi everbody,
I need to apply lasso regression using the function l1ce from the lasso2
package:
fr <- l1ce( fitness_T ~ ., data = dr, absolute.t=TRUE, standardize=FALSE );
Where fitness_T is my response, "." represents all the terms of my
dataframe dr. This function fails when I use a lot of variables (around
200-300 terms) in the dataframe. Is there any constraint about this?
This is the error message I get:
Error en l1ce(fitness_T ~ ., data = dr, absolute.t = TRUE, standardize =
FALSE) :
Oops, something went wrong in .C("lasso",..): -1
Sometimes I get the same error when I introduce dataframes like the
following (with only 30 terms):

I get the same error. Is there any constraint about the values that can
take the response in the formula of l1ce?
Can somebody help me?
Thank you for your help,
Miguel Ratón Almansa
