i have a wired problem. i want to count the unique entry in a certain column.Here i have attached my csv file.i am doing this to get the unique entries in the column. dat<-read.csv("C:/Project/Gawk-scripts/Book1.csv") names(dat)<-c("user_name") unique(dat$user_name) results says i have 170 unique values. But i am doing "remove duplicate entries" in excel i am having 147 unique entries in the column. Can anyone explain why there is a mismatch of the results or i am doing something wrong.
Surely you can just compare the lists. 147 is not that many entries, and if they are sorted, it will be easy.
