Add axis labels
tm_xlab(text, size = 0.8, rotation = 0, space = 0) tm_ylab(text, size = 0.8, rotation = 90, space = 0)
text |
text for the axis |
size |
fontsize, by default 0.8 |
rotation |
rotation angle in degrees. By default, 0 for the x axis label and 90 for the y axis label. |
space |
space between labels and the map in numbers of line heights. By default, it is 0, unless grid labels are plotted outside the frame (i.e., |
data(World) qtm(World, fill="#FFF8DC", projection=4326, inner.margins=0) + tm_grid(x = seq(-180, 180, by=20), y=seq(-90,90,by=10), col = "gray70") + tm_xlab("Longitude") + tm_ylab("Latitude")
