Convenience function for meme text position in a meme plot.
Usage
text_position(n)
Value
a list of meme text label position arguments: w (width), h (height),
and x and y coordinates.
Arguments
n
integer, number of meme text labels.
Details
This function takes an integer 1 or 2 and returns, respectively, top or
symmetrical top and bottom meme text position arguments. This function is
used as the default for the label_pos argument in meme. It is provided if
you do not want to bother with specifying coordinates and exact placement
does not matter. It is not intended for placement of more than two meme text
labels and any value other than 1 or 2 returns an error.
