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=
5 matches
