plotWalterLieth: Plot a Walter Lieth climate diagram

Description

This produces a Walter Lieth climate diagram from annual cycles of temperature and precipitation.

Usage

plotWalterLieth(X, station="", alt=NA, per, margin=c(4, 4, 5, 4),
pcol="#005ac8", tcol="#e81800", pfcol="#79e6e8", sfcol = "#09a0d1", shem=FALSE, ...)

Arguments

X

A dataclim object or a matrix.

station

A string describing the station. Defaults to the empty string "".

alt

The altitude of the station. Defaults to NA.

per

A string for the period over which the monthly averages are computed. Defaults to the basePeriod slot if X is of class dataclim or to the empty string "" if X is a matrix

margin

Vector with four numeric elements describing the margins of the plot. Defaults to c(4, 4, 5,4). See par().

pcol

Color for (p)recipitation. Defaults to "#005ac8".

tcol

Color for (t)emperature. Defaults to "#e81800".

pfcol

Color (p)robable (f)rost. Defaults to "#79e6e8".

sfcol

Color (s)ure (f)rost. Defaults to "#09a0d1".

shem

Logical. Is the station on the Southern hemisphere? Defaults to FALSE.

...

Further arguments passed to plot().

Value

Nothing. A plot.

Details

If X is an object of dataclim, the extracts the monthly averages from a call to summary(X) and produces the Walter Lieth climate diagram.

If X is a matrix, X is expected to be a 4x12 matrix with no NAs, with the first row: monthly precipitation (mm), second row: monthly average maximum daily temperature (degC), third row: monthly average minimum daily temperature (degC), forth row: monthly absolute minimum daily temperature.
