Plot a SpatGraticule. You can create a SpatGraticule with graticule.
# S4 method for SpatGraticule,missing
plot(x, y, background=NULL, col="black", mar=NULL, labels=TRUE,
retro=FALSE, lab.loc=c(1,1), lab.lon=NULL, lab.lat=NULL, lab.cex=0.65,
lab.col="black", off.lat=0.25, off.lon=0.25, box=FALSE, box.col="black",
add=FALSE, ...)
SpatRaster or SpatVector
missing or positive integer or name indicating the layer(s) to be plotted
background color. If NULL, no background is drawn
numeric vector of length 4 to set the margins of the plot. To make space for the legend you may use something like c(3.1, 3.1, 2.1, 7.1). To fill the plotting canvas, you can use c(0,0,0,0. Use NA to not set the margins
character. Color for the graticule lines
logical. If TRUE, show graticule labels
logical. If TRUE, show "retro" instead of decimal labels with the graticule
numeric. The first number indicates where the longitude graticule labels should be drawn (1=bottom, 2=top, NA=not drawn, any other number=top and bottom). The second number indicates where the latitude graticule labels should be drawn (1=left, 2=right, NA=not drawn, any other number=left and right)
positive integers between 1 and the number of labels, indicating which longitude graticule labels should be included
positive integers between 1 and the number of labels, indicating which latitude graticule labels should be included
double. size of the label font
character. color of the labels
numeric. longitude labels offset
numeric. latitude labels offset
logical. If TRUE, the outer lines of the graticule are drawn on top with a sold line lty=1
character. color of the outer lines of the graticule if box=TRUE
logical. Add the graticule to the current plot?
additional graphical arguments passed to lines
g <- graticule(60, 30, crs="+proj=robin")
plot(g, background="azure", col="red", lty=2, box=TRUE)
plot(g, background="azure", col="light gray", lab.loc=c(1,2),
lab.lon=c(2,4,6), lab.lat=3:5, lty=3, retro=TRUE)
