Numeric sample names not working

[danmaclean]

Using numeric data for samples apparently doesnt work. Needs a check and potential fix.

Error given when attempting to make plots after running estimate:

Error in ggridges::stat_density_ridges():
! Problem while setting up geom.
ℹ Error occurred in the 1st layer.
Caused by error in compute_geom_1():
! geom_density_ridges_gradient() requires the following missing
aesthetics: y
Run rlang::last_error() to see where the error occurred.
Warning message:
The following aesthetics were dropped during statistical transformation: y
ℹ This can happen when ggplot fails to infer the correct grouping structure in
the data.
ℹ Did you forget to specify a group aesthetic or to convert a numerical
variable into a factor?

A roundabout is simply to ensure all sample IDs are not solely numeric, though there maybe a more elegant solution.
