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.
