Plot long-lat grid over projected data
llgridlines(obj, easts, norths, ndiscr = 20, lty = 2, offset=0.5, side="WS", llcrs = "+proj=longlat +datum=WGS84", plotLines = TRUE, plotLabels = TRUE, ...)
obj | object, deriving from Spatial-class having projection specified |
---|---|
easts | numeric; see gridlines |
norths | numeric; see gridlines |
ndiscr | numeric; see gridlines |
offset | numeric; see gridlines |
side | character, default “WS”; see gridlines; available from sp 0.9-84 |
lty | line type to be used for grid lines |
llcrs | proj4string of longitude - latitude |
plotLines | logical; plot lines? |
plotLabels | logical; plot labels? |
... | graphics arguments passed to plot function for lines and text function for labels |
none; side effect is that grid lines and lables are plotted
