Description

This is a column version of deleteBogusRows. Use the pm argument to set the proportion of missing required before a column is flagged for deletion

Arguments

dframe

A data frame or matrix

pm

"proportion missing data" to be tolerated.

drop

n

Default 25: limit on number of values to print in diagnostic output. If set to NULL or NA, then all of the column values will be printed for the bogus rows.
