mapdims - grave accents appearing for rowwise and not colwise

[robertschnitman]

ISSUE: The output in mapdims() produces grave accents (`) for the name of the row results; however, it was not the case for the column-wise list element. Why the inconsistency?

Attempts to remove the grave accents were not successful at this point: initial methods employed to overwrite the names were the assignment operator, make.names(), and gsub().

Example
