Hello,

   I have been trying to apply some of the different ways suggested in the past to replace empty values in a vector for a letter, without success.

   Actually, I have a data frame that might contain empty values, I need to replace all those empty values for the letter 'N'.

  This was my latest try:

   dat<-read.csv('myfile.csv', na.strings="")        



Be a better friend, newshound, and
