plotuspar {Maeswrap} | R Documentation |
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.

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 |
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.
A lattice device, or a pdf.
