I originally had a wide CSV dataset of about 18000 columns(and about 80 rows) that I am trying to read in R. It was stored in an Excel sheet,which unfortunately has a limit of only 16384 columns. Hence, taking the dimension I obtain:
> dim(train_set)  83 16384
i.e 1000+ columns are getting eaten up ,and this would badly affect the accuracy of the predictions. How can I read all the columns in R?
Your suggestions are much appreciated. Thanks a lot!
