Adding legend title and main title in ggplot2

Question

Hi I am trying to use ggplot2 to do the following

1) Change the legend name to \"asset\" 2) Add a title to the top 3) Change the border of each panel to a more solid da

Answer 1

1) You can change the legend name to "Asset" by putting "Asset" as the first parameter in the scale_color_manual function.

scale_colour_manual("Asset",values = ...)

2) You can do

p<-p+labs(title="PUT TITLE HERE")

for the title

3) You can add an additional argument to theme() to change the background color (which will make a border appear around the box)

p<-p+theme(panel.background = element_rect(fill=NA, col="black"))

You could also try adding p=p+theme_bw() earlier in the expression, but that might change too many things.

4) For the grid labels, you have 2 options (well, more, but these are the easiest). Firstly, you can rename the levels of your data. If you don't want to do that, you can make a labeller function to pass as an argument in facet_grid(). See the example here:

For the color of the panel, you can also use theme() for that

p<-p+theme(strip.background = element_rect(fill = 'purple'))#turns boxes purple
