Validate unique column names #93

Closed DavisVaughan closed 4 years ago

DavisVaughan commented 5 years ago

This would be an optional but helpful check that column names in the data frame / matrix are unique. Maybe with vec_as_names(repair = "check_unique")

DavisVaughan commented 4 years ago

The vec_as_names() errors are so good we might as well just encourage people to use that. The only reason to wrap it would be to give our own error message, but I don't think we need that.

library(vctrs)

vec_as_names(c("..1", "..2"), repair = "check_unique")
#> Error: Names must not be of the form `...` or `..j`.

vec_as_names(c("", "x"), repair = "check_unique")
#> Error: Names must not be empty.

vec_as_names(c("x", "x"), repair = "check_unique")
#> Error: Names must be unique.
