| deleteBogusColumns {kutils} | R Documentation |
Remove columns in which the proportion of missing data exceeds a threshold.
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. |
