deleteBogusColumns: Remove columns in which the proportion of missing data exceeds
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
Usage
deleteBogusColumns(dframe, pm = 0.9, drop = FALSE, verbose = TRUE,
n = 25)
Arguments
dframe
A data frame or matrix
pm
"proportion missing data" to be tolerated.
drop
Default FALSE: if data frame result is reduced to one
column, should R's default drop behavior "demote" this to a
column vector.
verbose
Default TRUE. Should a report be printed
summarizing information to be delted?
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.
