climateGraph: climate graph after Walter and Lieth

Description

Draw a climate diagram by the standards of Walter and Lieth.

Usage

climateGraph(temp, rain,
  main = "StatName\n52\U{00B0}24' N / 12\U{00B0}58' E\n42 m aSL",
  units = c("\U{00B0}C", "mm"), labs = substr(month.abb, 1, 1), 
  textprop = 0.25, ylim = range(temp, rain/2), compress = FALSE,
  ticklab = -8:30 * 10, ticklin = -15:60 * 5, box = TRUE,
  mar = c(1.5, 2.3, 4.5, 0.2), keeppar = TRUE, colrain = "blue",
  coltemp = "red", lwd = 2, arghumi = NULL, argarid = NULL,
  argcomp = NULL, arggrid = NULL, argtext = NULL, ...)

Value

None. Plots data and table.

Arguments

temp: monthly temperature mean in degrees C
rain: monthly rain sum in mm (12 values)
main: location info as character string. can have \n. DEFAULT: "StatName\n52d 24' N / 12d 58' E\n42 m aSL"
units: units used for labeling. DEFAULT: c("d C", "mm")
labs: labels for x axis. DEFAULT: J,F,M,A,M,J,J,A,S,O,N,D
textprop: proportion of graphic that is used for writing the values in a table to the right. DEFAULT: 0.25
ylim: limit for y axis in temp units. DEFAULT: range(temp, rain/2)
compress: should rain>100 mm be compressed with adjusted labeling? (not recommended for casual visualization!). DEFAULT: FALSE
ticklab: positions for vertical labeling. DEFAULT: -8:30*10
ticklin: positions for horizontal line drawing. DEFAULT: -15:60*5
box: draw box along outer margins of graph? DEFAULT: TRUE
mar: plot margins. DEFAULT: c(1.5,2.3,4.5,0.2)
keeppar: Keep the changed graphical parameters? DEFAULT: TRUE
colrain: Color for rain line and axis labels. DEFAULT: "blue"
coltemp: color for temperature line and axis labels. DEFAULT: "red"
lwd: line width of actual temp and rain lines. DEFAULT: 2
arghumi: List of arguments for humid polygon, like density, angle. DEFAULT: NULL (internal x,y, col, border)
argarid: List of arguments for arid area. DEFAULT: NULL
argcomp: List of arguments for compressed rainfall polygon. DEFAULT: NULL
arggrid: List of arguments for background grid lines. DEFAULT: NULL
argtext: List of arguments for text at right hand if textprop>0. DEFAULT: NULL
...: further arguments passed to plot, like col.main
