R help - Dec 2015 - tmap colour scale

Hi,

I am trying to plot Conservative Vote % per borough for London using tmap
however the legend colours boroughs with a high Conservative % as light blue and
boroughs with a low % of conservative votes as dark blue. How do i reverse this
scale so that areas with the most Conservative votes are darkest?

my code is as follows;

tm_shape(lndbor) + tm_polygons("CON", style = "kmeans",
palette = "-Blues", title = "Conservative Vote (%)")

Thanks,

Hi Freddy,
Have you tried rev() on the palette?

Jim
