Hi, I need your help!! I imported a big coloumn vector from a txt file but it results as mode :"list" I want to change it in numeric otherwise I can't do my analysis. This is what i get: mode (data) <- "double" Error in eval(expr, envir, enclos) : (list) object cannot be coerced to type 'double'>Thanks a lot!!!
