x |
object of class |
var |
name(s) of the variable(s) to plot |
inches |
size of the biggest symbol (radius for circles, half width for squares) in inches. |
val_max |
maximum value used for proportional symbols |
lwd_max |
line width of the largest line |
symbol |
type of symbols, 'circle' or 'square' |
col |
color |
border |
border color |
lwd |
border width |
leg_pos |
position of the legend, one of 'topleft', 'top','topright', 'right', 'bottomright', 'bottom', 'bottomleft', 'left' or a vector of two coordinates in map units (c(x, y)). If leg_pos = NA then the legend is not plotted. If leg_pos = 'interactive' click onthe map to choose the legend position. |
leg_title |
legend title |
leg_title_cex |
size of the legend title |
leg_val_cex |
size of the values in the legend |
leg_val_rnd |
number of decimal places of the values in the legend |
leg_frame |
whether to add a frame to the legend (TRUE) or not (FALSE) |
add |
whether to add the layer to an existing plot (TRUE) or not (FALSE) |
x is (invisibly) returned.
