solar.cycle: Solar cycles on ggplots
In proto4426/ValUSunSSN: Val-U-Sun project functions

Description Usage Arguments Details Value Author(s) Examples

Function to plot vertical lines for adding to ggplots, which correspond to the solar cycles. Dates found for the solar Cycles comes from https://en.wikipedia.org/wiki/List_of_solar_cycles

1	solar.cycle(col = 3, size = 0.3)

`col`	choose color for the vertical lines
`size`	choose size for the lines

This function is useful to decrease the amount of code for each ggplots generated as this thesis will use exclusive ggplot2 for the plots. Values of other parameters such as colours could be changed inside the function.
