Description
discrete_ranks
Usage
discrete_ranks(x, ranks = NULL)
Arguments
x |
A dataframe containing hierarchically structured information, for example a table of genus names and their higher taxonomic classifications |
ranks |
If not NULL, a vector of column names of x, given in rank order. This is useful if x contains columns which are not rank relevant or if columns are not in hierarchical order. If not supplied, the column order in x is used directly and is assumed to be in rank order |
Details
Function for checking whether names in one column of a hierarchically organised dataframe re-occur at other levels. Two checks are performed. The first checks for names in adjacent column, assuming that accidental reuse of names at other levels are most likely to occur at an adjacent rank. The second compares across all columns.
Value
A list of two lists. The first list contains names which reoccur at adjacent ranks. The second list contains names that reoccur at any rank
Examples
# load dataset
data("brachios")
# define ranks
b_ranks <- c("phylum", "class", "order", "family", "genus")
# run function
flag <- discrete_ranks(brachios, ranks = b_ranks)
