^^^^^^^^^^^ Just to pick a nit: Could we make a habit of distinguishing between "names" and "identifiers"? The latter being the syntactical term in the R language, briefly the names that you don't need to use get() to access. "123" and "Height in cm" are valid names, but not valid identifiers.
The argument is called `check.names', and has description
check.names: if `TRUE' then the names of the variables in the data
frame are checked to ensure that they are valid variable
names. If necessary they are adjusted (by `make.names') so
that they are.
So `make.names' should be renamed as `make.identifiers'. That is
described as
make.names package:base R Documentation
Make Legal R Names Out of Strings
Description:
Make legal R names out of every `names[i]' string. Invalid
characters are translated to `"."'.
More plausibly, you are proposing a new distinction ....
