I'm trying to see if & how I can use coord_trans() with ggplot2 to transform the Y axis
of a plot on the logit scale to the probability scale, as opposed to recalculating

Sorry I jumped the gun. That does not provide you with the same plot as gg2
that you are aiming for.

I think all you have to do is add type="response" to your call for the
predictions.
Does this work for you
# get fitted values on the logit scale
pred <- data.frame(Arthritis,
predict(arth.logistic, se.fit=TRUE,type="response"))
library(ggplot2)
library(scales)
# plot on logit
I'm trying to see if & how I can use coord_trans() with ggplot2 to
transform the
Y axis of a plot on the logit scale to the probability scale, as opposed
to recalculating
everything "manually" and constructing a new plot.
Here is a simple example of the 'base' plot I'd like to transform:
