check_pop_levels.RdCheck that pop.levels and pop.labels and pop.select arguments are used correctly and that the values are cleaned for spaces.
check_pop_levels(pop.levels = NULL, pop.labels = NULL, pop.select = NULL)(optional, string) This refers to the levels in a factor. In this
case, the id of the pop.
Use this argument to have the pop ordered your way instead of the default
alphabetical or numerical order. e.g. pop.levels = c("QUE", "ONT", "ALB")
instead of the default pop.levels = c("ALB", "ONT", "QUE").
White spaces in population names are replaced by underscore.
Default: pop.levels = NULL.
(optional, string) Use this argument to rename/relabel
your pop or combine your pop. e.g. To combine "QUE" and "ONT"
into a new pop called "NEW":
(1) First, define the levels for your pop with pop.levels argument:
pop.levels = c("QUE", "ONT", "ALB").
(2) then, use pop.labels argument:
pop.labels = c("NEW", "NEW", "ALB").
To rename "QUE" to "TAS":
pop.labels = c("TAS", "ONT", "ALB").
Default: pop.labels = NULL.
White spaces in population names are replaced by underscore.
(optional, string) Selected list of populations for
the analysis. e.g. pop.select = c("QUE", "ONT") to select QUE
and ONT population samples (out of 20 pops). If pop.labels
argument was used to rename the strata column, use the new names with
pop.select.
Default: pop.select = NULL
