Dear R list I have a problem with NA, which should be a string, but R seems that it doesn't recognize it. What I do is first give the format command to my data frame:
format.data.frame(mydata,big.mark=" ") so I give a blank as thousand separator. All my records in my data frame become strings, so instead of having NA I have "NA". I try to convert "NA" in ".",but it seems that R doesn't recognize "NA". Someone knows why and how to treats those "NA"??
