Spacing Between Legend Entries - legend.position = "bottom"

[Lighton Phiri]

What properties can I use to create adequate spacing between legend
entries when I place a legend at the bottom on my plot? My legend
entries are too close together --see attachment.

You can adjust the text size of the legend. 

Alternatively, you could play with the DPI settings of the output (?quartz(), ?windows(), ?x11(), or ?ggsave() ). 

If you want to simply spread them out more... I'm not sure. Attached is a transition document that Dennis Murphy put together that has all of the editable features (at least superficially) and I don't see how.

I managed to sort this out using an approach Ista suggested in another
one of my posts [1] --basically appending spaces using 'paste'
function
