Add labels to a map
Plots labels, that is a textual (rather than color) representation of values, on top an existing plot (map). methods
## S4 method for signature 'SpatRaster' text(x, labels, digits=0, halo=FALSE, hc="white", hw=0.1, ...) ## S4 method for signature 'SpatVector' text(x, labels, halo=FALSE, inside=FALSE, hc="white", hw=0.1, ...)
x
: SpatRaster or SpatVectorlabels
: character. Optional. Vector of labels with length(x)
or a variable name from names(x)
digits
: integer. How many digits should be used?halo
: logical. If TRUE
a "halo" is printed around the texthc
: character. The halo colorhw
: numeric. The halo widthinside
: logical. Should the text always be placed inside one the sub-geometries?...
: additional arguments to pass to graphics function text
