Reading a wide dataset in R 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: 

&gt; dim(train_set)
[1]    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!
Refer to my comment, I believe what you need is  

df &lt;- read.csv("./yourpath/yourfile", sep = ";", header = TRUE) # play around with the arguments per your file.
