Abbreviate treatment names
Auxiliary function to create uniquely abbreviated treatment names.
treats(x, nchar.trts = 8, row = TRUE)
x |
A vector with treatment names or a matrix with treatment names as row and / or column names. |
nchar.trts |
A numeric defining the minimum number of characters used to create unique treatment names. |
row |
A logical indicating whether row or column names should
be used (only considered if argument |
This auxiliary function can be used to create uniquely abbreviated treatment names (and is used internally in several R functions for this purpose).
Initially, to construct uniquely abbreviated treatment names,
substring is used to extract the first
nchar.trts characters. If these abbreviated treatment names
are not unique, abbreviate with argument
minlength = nchar.trts is used.
