Hi R users, I have a string for example 'X35.84375_.100.71875', and I have another dataframe df that I want to export with the transformed string name '35.84375_-100.71875' with no extension. How to do this in R? Thanks for your help. a = 'X35.84375_.100.71875' write.table(df, file='', row.names=F, col.names=F) [[alternative HTML version deleted]]
