Details

Twenty-six variables a-z are defined as their mvp semantic equivalent:

a <- as.mvp("a")
    ...
    z <- as.mvp("z")

These objects can be generated by running script inst/symb.Rmd, which includes some further discussion and technical documentation and creates file lettersymbols.rda which resides in the data/ directory.

Letters c, q, and t might pose difficulties.
