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.

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

a single numeric vector to be described.

xname

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 is

...

further argument to be passed to methods.

A list containing the following components:
lengththe length of the vector (n + NAs).
nthe valid entries (NAs are excluded)
NAsnumber of NAs
uniquenumber of unique values.
0snumber of zeros
meanarithmetic mean
meanSEstandard error of the mean, as calculated by MeanSE.
quanta table of quantiles, as calculated by quantile with probs set to c(.05, .10, .25, .5, .75, .9, .95).
sdstandard deviation
vcoefcoefficient of variation: mean(x) / sd(x)
madmedian absolute deviation (mad)
IQRinterquartile range
skewskewness, as calculated by Skew.
kurtkurtosis, as calculated by Kurt.
highlowthe lowest and the highest values, reported with their frequencies in brackets, if > 1.

The plot function used here is PlotFdist.

Desc(d.pizza$temperature)

# contains all results of:
quantile(d.pizza$temperature, na.rm=TRUE)
