Hello, I have a CSV file with region codes listed in a column. E.g. 'AS' for Asia, 'AU' for Australia and 'NA' North America.
However, the data frame created using read.csv shows <NA> where the string variable should have had the value 'NA'. How can I input the value 'NA' present in a column in a CSV file without R changing it to missing? Thanks Nikhil [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
