formatTableColumns.RdFormat columns in a data.frame.
formatTableColumns(tbl, columns, signifDigits, maxLevels = 10)A data.frame or similar object.
Character vector giving the column names of tbl that
should be formatted.
Numeric scalar, the number of significant digits to
round numeric columns to. Set to NULL to skip rounding.
Numeric scalar. If character columns have at most this number of unique values, they will be encoded as factors.
The input data.frame with formatted columns.
