plotuspar: Plot the understorey PAR points

In Maeswrap: Wrapper Functions for MAESTRA/MAESPA

Description

Reads the 'uspar.dat' file in the current working directory, and plots the incident or absorbed (or diffuse, or direct) PAR at the understorey points. Either produces a plot, or makes a pdf with a plot for each hour of the selected day.

Reads the point-wise output file when the understorey was simulated.

Usage

plotuspar(what = c("PARbeam", "PARtotal", "PARdiffuse", "APAR"),
  dataset = NULL, day = 1, hour = NA, xlim = NULL, ylim = NULL,
  makepdf = FALSE, outputfile = "aparunderstorey.pdf", scaleeach = TRUE,
  addNarrow = TRUE)

readuspar(filename = "uspar.dat")

Arguments

what	Either 'diff', 'apar', 'ipar', or 'beam' (the default).
dataset	If left alone, reads the uspar dataset.
day	Which day to use, if left alone uses the first day only.
hour	Which hour to plot. If left alone, makes a plot for each hour.
xlim,ylim	X- and Y-axis limits.
makepdf	Logical. If TRUE, produces a pdf in the working directory.
outputfile	Name of the pdf file.
scaleeach	Logical. Rescale grey scale for each plot, or same for all hours?
addNarrow	Logical. Add an arrow pointing North.
filename	The understorey file

Details

If addNarrow is TRUE, attempts to read the trees.dat file in the current working directory as well. Prints a warning when this file cannot be opened.

Value

A lattice device, or a pdf.

Examples

## Not run: 

# Plot one hour of the first day, showing incident PAR on understorey:
plotuspar("ipar", day=1,hour=12,makepdf=FALSE)

# Make pdf of the whole day, plotting beam radiation:
plotuspar("beam", day=1, outputfile="beam uspar")


## End(Not run)
