Tag ggplot2 graphics with standard meta-information
The primary ggTag function embeds a ggplot object within a grid framework. The function allows a user to add titles and meta information to the outer border of a plot along with file path and date-time stamps (which are automatically added upon execution). An existing ggplot title can be moved from the original graphic to the outer framework.
devtools::install_github("andyofsmeg/ggTag")The main package function ggTag can simply take a ggplot2 object and will automatically add the appropriate meta-information. Additional information can be supplied as arguments to the function.

# Now let's tag it

ggTag(my_scat,
meta = list(top_left = "Analysis ID 123456", top_right = "Page 1 of 1"),
