Check the use of pop.levels, pop.labels and pop.select arguments.

Check that pop.levels and pop.labels and pop.select arguments are used correctly and that the values are cleaned for spaces.

Usage

check_pop_levels(pop.levels = NULL, pop.labels = NULL, pop.select = NULL)

pop.levels: (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.
pop.labels: (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.
pop.select: (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.
