Desc.numeric: Describe a numeric vector

Description

This reports a rich description of a numeric vector, consisting of the most common descriptive measures for location and variability.

Usage

## S3 method for class 'numeric':
Desc(x, main = NULL, highlow = TRUE, plotit = getOption("plotit", FALSE), ...)

Arguments

x

a single numeric vector to be described.

main

the caption for the output.

highlow

boolean. Should the highest and the lowest values be reported. This is usually a good idea and so the default is TRUE.

plotit

boolean. Should a plot be created? The vector would be plotted by means of PlotDesc.numeric, which again basically is PlotFdist. Default can b

...

further argument to be passed to methods.

Value

• A list containing the following components:
• length
  the length of the vector (n + NAs).
• n
  the valid entries (NAs are excluded)
• NAs
  number of NAs
• unique
  number of unique values.
• 0s
  number of zeros
• mean
  arithmetic mean
• meanSE
  standard error of the mean, as calculated by MeanSE.
• quant
  a table of quantiles, as calculated by quantile with probs set to c(.05, .10, .25, .5, .75, .9, .95).
• sd
  standard deviation
• vcoef
  coefficient of variation: mean(x) / sd(x)
• mad
