By default a formula of x on y is converted into a formula of y
on x, while the reverse swap is done only if backward = TRUE
.
swap_xy(f, backwards = FALSE)
A copy of f
with x
and y
swapped by each other
in the lhs and rhs.

This function is meant to be used only as a helper within 'ggplot2'
statistics. Normally together with geometries supporting orientation when
we want to automate the change in orientation based on a user-supplied
formula. Only x
and y
are changed, and in other respects
the formula is rebuilt copying the environment from f
.
