Thanks Duncan, This type.convert works fine for me and gives me TSTMean with decimal, but I want to add this result as a new column to my df as int or num, how can I do this? Thanks, Elahe

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.
