I have created a map of london showing a crime figures. As you can see from my image below - my legend is in a awkward place - i'd prefer it to be on the bottom left or right? anyone know how I could possibly do this. My code that I have created the map with is below.
Also how would i create a title for the map - I have already created the legend title.
qtm(brgh, fill = "Theft15", fill.title="Number of recorded thefts")
Since I do not have your data, I decided to use data from the tmap package for the following demonstration. The key point is to use tm_legend(). If you look into the current CRAN manual, you can find more information in the tm_layout() section. You can specify a position of legend using legend.position in tm_legend(). For main title, you can use main.title and main.title.position in the function.
library(tmap)
data(World, rivers, metro)
qtm(shp = World, fill = "economy", format = "World", style = "col_blind") +
tm_legend(legend.position = c("left", "top"),
main.title = "My title",
main.title.position = "right")
qtm(shp = World, fill = "economy", format = "World", style = "col_blind") +
tm_legend(legend.position = c("left", "bottom"),
main.title = "My title",
main.title.position = "right")
