No way to remove duplicate column names

[jzadra]

Some joins will allow a tibble to end up with two columns with identical names. Doing any sort of tidyselect operation on the tibble results in:

Error: Can't bind data because some arguments have the same name

However, there doesn't appear to be any way to remove the duplicated column. It seems to me that using select(-matches("duplicate name")) or select(-contains("duplicated name")) ought to work since they allow catching multiples. In addition, selecting based on the index should also work. If columns 100 and 101 have the same name, I should be able to select(-101) however these all result in the same Error: Can't bind data because some arguments have the same name

Thanks for that. My only concern about this as a long term solution would be the risk of affecting other names in the tibble unintentionally.

test[!duplicated(names(test))] is probably the safest way to go

We now have the tooling to handle this in the dev version of tidyselect and it should be straight forward to update dplyr.
