It is the r-lib and tidyverse equivalent of base::make.names(). vctrs deals with a few levels of name repair: minimal names exist. The names attribute is not NULL.

Perhaps it is a model of serum concentrations of a drug that rise rapidly to a peak concentration and then decay exponentially. Easy enough, use nonlinear regression ([R] nl) to [...] | ||
