reading csv file : blanks
Hi, I have a comma seperated data file which has blanks in it. I am trinying to import it to R using data1<-read.csv("oa_2006.csv", header = TRUE, sep = ",", quote="\"", dec=".") I want the missing values to be "NA". instead R reads them as "U". Any idea why this happens ? Thanks in advance. Regards, Nataraju GM [[alternative HTML version deleted]]
