Hello,
Could someone tell me, how can I select from a dataframe only those columns
whose names contain a certain text?
For example, if the column names are
"Bond1.Creditclass","Bond1.Price","Bond2.Creditclass","Bond2.Price", how do I
select only the columns corresponding to Bond1?
Thanks a lot,
Mihai
