Extract the Label for a Variable
Extracts the label for a variable from one or more of the *Labels
files. This is useful for plots and other displays because the variable
names are often cryptically short.

Lahman::fieldingLabels))var |
name of a variable |
labels |
label table(s) to search, a 2-column dataframe containing variable names and labels. |
