Hi, I was trying to import a csv data set using proc import. My csv file contains numbers and some NaNs. However whenever there is a NaN in the first column of a row, SAS will issue a NOTE and write it as a missing value ' . '. In this case, only the NaN in the first column are read as ' . ' and the rest NaN are NaN in the SAS output. I wonder if there is way to have all NaN from the original file displayed uniformly as NaN or ' . '? Perhaps also have proc import stopping issue NOTE? I would appreciate your help and comment. Thank you. Mona ... View more
