plot.wlai {BIOdry}R Documentation

Plot an wlai object

Description

A Walter-Lieth climate diagram is produced.

Usage

## S3 method for class 'wlai'
plot(x, ...)

Arguments

x

vector or data.frame. An object inheriting from class wlai, representing the Aridity Index.

...

logical. Further arguments passed to plot function.

Details

Areas between temperature and precipitation lines when precipitation exceeds temperature (moist seasons) are plotted in gray color, and areas where temperature exceeds precipitation (dry seasons) are plotted in black color. Monthly cumulative precipitations over 100 mm are scaled such that 1 degree C of average temperature is equal to 5 mm of precipitation.

Value

A plot of the Walter-Lieth diagram.

Examples

##random simulation of climatic records
set.seed(1)
pr <- rnorm(12,1,1)
tm <- rnorm(12,0,1)
cld <- data.frame(pr,tm)
##labels of months from october to september
rownames(cld) <- month.abb[c(10:12,1:9)]
rownames(cld) <- c(10:12,1:9)
##computation of the aridity index and climate diagram
AI <- wlai(cld)
plot.wlai(AI)
