tm_xlab: Axis labels

Description

Add axis labels

Usage

tm_xlab(text, size = 0.8, rotation = 0, space = 0)
tm_ylab(text, size = 0.8, rotation = 90, space = 0)

Arguments

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., tm_grid is called with labels.inside.frame = FALSE). In that case, space corresponds to the height of one line, taking the grid label size into account.

Examples

# NOT RUN {
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")
# }
