Description Usage Arguments See Also

Draws contours on a plot map. Elevmat has elevation data in matrix form; plot dimensions are not needed, instead it calculates them from elevmat and the gridsize.

maptopo(elevmat, plotdim, add = FALSE, new = FALSE, export = "no",
  interval = 0, xrange = NULL, yrange = NULL, xaxis = TRUE,
  yaxis = TRUE, axspos = 0.5, labelsize = 1.15, maintitle = "",
  ht = 6, wd = 9, plotside = 4.5, filepath = "", clr = "black",
  bgcolor = "transparent")

`elevmat`	Matrix of elevation data (see ?bciex::bci_elevation).
`plotdim`	The x and y dimensions of the plot.
`add`	Logical. Whether to add elements such as points or line to an existing graph. if TRUE, there must be an appropriate existing graph, otherwise, a new graph is drawn.
`new`	If `TRUE`, a new screen window is created.. See `graphics::par()`.
`export`	`export = "no"`, does nothing, so the next graph uses the default R device. With this option, the size of the graph cannot have been set larger than the default size, which is usually 7 inches. `export = "unix"`, a new graphics window in unix, size `h` and width `w`, will be opened allowing you to alter the size of the output. `export = "windows"`, or `export = "mac"` are similar to `export = "unix"` but for windows and mac. `export = format` exports the graph to a specific file format: "pdf", "png", "jpg", "bmp", "emf".
`interval`	Contour line intervals.
`xrange`	Minimum and maximum x and y coordinates of area graphed. If `NULL`, all `x` (or `y`) are included.
`yrange`	Minimum and maximum x and y coordinates of area graphed. If `NULL`, all `x` (or `y`) are included.
`xaxis`	xxxdocparam
`yaxis`	xxxdocparam
`axspos`	Distance between axis numbers and axis.
`labelsize`	xxxdocparam
`maintitle`	A title to appear at the top of the page, above the species name.
`ht`	Height and width of the overall graph. The default work for pdf export or mapping to the screen, and ht and wd are inches. But if export is png, jpg, emf, height and width are pixels and need to be 500-1000.
`wd`	Height and width of the overall graph. The default work for pdf export or mapping to the screen, and ht and wd are inches. But if export is png, jpg, emf, height and width are pixels and need to be 500-1000.
`plotside`	The vertical dimension (inches) of the map.
`filepath`	The folder to which map will be exported.
`clr`	A string indicating colour. See argument col in `graphics::par()`.
`bgcolor`	The background color. Defaults to white. For presentation exports, try bgcolor="transparent".
