[R] Problem in generating any model with my dataset in R

Hi

Why do you replace NA with meaningless „-„? NA for R means Not Available and R can handle it properly. „-„ means „-„ for R and is treated as character together with rest of the column. If somebody aviced it to you, do not trust him any more.

Anyway, you still do not provide info about data. If you have so many rows maybe the best way would be

dput(head(yourdata[1:50,])

or something like that.

Cheers
Petr

Thank you very much for your suggestion,
I am running this on windows using R 3.2.2 and also I tried on linux as well.

In my data, some of the rows having "NA" and before using my dataset I am replacing this NA with "-", can this create a problem?

Hi

Your objects are not so big, therefore I assume that something is wrong with their stucture, especially when one object gives you results.

I wonder if you get more precise answer without providing some basic facts (structure of data, code, OS, R version).

Cheers
Petr
