Hi all, I have a df which a part of this is:TSTMax :int 213 228 227 281 TSTMin :int 149 167 158 176 TSTMean :Factor w/94 levels "100,2" , "104,3" , ... I want to change the TSTMean into numeric but by using as.numeric(as.character(df$TSTMean)) I get too many NAs. Is there a way to change TSTMean into numeric without those NAs? I want TSTMean to be at the end like: TSTMean :int 100.2 104.3 .....
You appear to have a comma as the decimal marker, so you can use type.convert(as.character(df$TSTMean), dec = ",", as.is = TRUE) instead of as.numeric().
A simpler approach might be to avoid getting the factor in the first place; if you read this data using read.table, there is the dec option to recognize a comma as the decimal separator.
