Usage

clean_empty_rows(
  x,
  absence.values = c(".", "0"),
  preserve.cols = NULL,
  preserve.rows = NULL
)

Arguments

x

matrix A relevé table.

absence.values

character A vector, with values representing absences. Defaults to c(".","0").

preserve.cols

numeric A vector containing the indices of the columns that should not be considered while cleaning (e.g., that don't correspond to relevés, but to taxa names).

preserve.rows

numeric A vector containing the indices of the rows that should not be considered while cleaning (e.g., that don't correspond to taxa, but to header lines).

Value

A matrix as (x), possibly without empty rows. Column and row order might be changed. See Details.

Details

This function deletes the empty rows from a relevé table. Row names from deleted rows will be lost. Column and row order might be changed, as preserved columns (preserve.cols) are placed on the left part of the output, and preserved rows (preserve.rows) are placed in the top part of the output.
