maptopo {CTFS} | R Documentation |
Draws a contour plot (default to 5 m intervals) for a CTFS Plot. This function can be run independently or in order to add a contour plot to a plot of the tree location of a species. The defaults provide a “nice” plot.
maptopo(elevmat, plotdim = c(1000, 500), add = FALSE, export = "no", interval = 0, maintitle = "Topographic Contours", ht = 6, wd = 9, plotside = 4.5, filename = "maptopo")
elevmat |
matrix of elevation data, preferably at 5 x 5 m
scale, usually the matrix component of the list bcitopo.info |
plotdim |
vector of 2 numbers, maximum x, y dimensions of plot in m |
add |
logical, TRUE = add contour plot to tree plot, only for use when NOT run independently, FALSE = for making contour plot only |
export |
character, indicating whether to plot to window or save as
file. Possible values are: “no ”, “bmp ”,
“jpg ”, “emf ”, “pdf ” |
interval |
contour line intervals |
maintitle |
character string, main title for plot |
ht |
height of graphics window, in inches |
wd |
width of graphics window, in inches |
plotside |
size of plot within the graphics window |
filename |
default filename for export |
This function can be run independently to just produce a contour plot
or can be called from map
to add a contour plot to a plot
of tree location for a species.
Make sure that elevmat
is a matrix. In most cases this would be
the matrix component of the list bcitopo.info
.
If export=
“no
” then a map is plotted in a window and all
information requested in plotted in the window. If the user choses to
export the file, then the same plot on the screen will be saved in a
file in the working directory in the format of the users choice. See
above for file name creation.
