Frequency Tables for Factors and other Discrete Data

Displays frequencies as well as valid/missing observation information.

freq(x, round.digits=2, style="simple", justify="right",
     plain.ascii=TRUE, file=NA, append=FALSE,
     escape.pipe=FALSE, ...)

`x`	Vector of discrete (categorical) data.
`round.digits`	Number of sig. digits to keep in output. Defaults to `2`.
`style`	Style of pander tables, one of “simple” (default), “multiline”, “grid” and “rmarkdown”.
`justify`	pander argument. Defaults to "right".
`plain.ascii`	pander argument; when results are displayed in console, this avoids having markdown markup characters int the tables. Defaults to TRUE.
`file`	File name to write output to. Defaults to `NA`. To append output to an existing text file, use `append=TRUE`.
`append`	When “file” argument is supplied, this indicates whether to append output to existing file (`TRUE`) or to overwrite any existing file (`FALSE`, default). If `TRUE` and no file exists, a new file will be created.
`escape.pipe`	Only useful when `style='grid'` and `file` argument is not `NA`, in which case it will escape the pipe character (\|) to allow Pandoc to correctly convert multiline cells.
`...`	Additional arguments passed to pander.

A frequency table of class matrix.
