These helpers facilitates generating theme compliant axes when building up the plot.
render_axes(x = NULL, y = NULL, coord, theme, transpose = FALSE)A list of ranges as available to the draw_panel method in
Facet subclasses.
A Coord object
A theme object
Should the output be transposed?
A list with the element "x" and "y" each containing axis
specifications for the ranges passed in. Each axis specification is a list
with a "top" and "bottom" element for x-axes and "left" and "right" element
for y-axis, holding the respective axis grobs. Depending on the content of x
and y some of the grobs might be zeroGrobs. If transpose=TRUE the
content of the x and y elements will be transposed so e.g. all left-axes are
collected in a left element as a list of grobs.
