R Documentation

Descriptive Univariate Statistics for Numerical Data

Description

Calculates mean, standard deviation, min, max, median, MAD, IQR, CV, skewness, SE.skewness, and kurtosis.

Usage

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

Arguments

`x`	Numerical vector.
`na.rm`	argument to be passed to statistical functions. Defaults to `TRUE`.
`style`	Style of pander tables. Defaults to dQuotegrid.
`round.digits`	Number of sig. digits to keep. Defaults to `2`.
`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.
`transpose`	Makes variables appears as columns, and stats as rows. Defaults to `FALSE`.
`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.

Value

A list with 2 elements; first one in a matrix (table) containing all the stats. Second, a table of statistics and table of counts (valid vs <NA> observations).
