According to ?ros, one of the arguments is:
reverseT: A name of a function to use for reversing the transformation
after performing the ROS fit. Defaults to 'exp'.
And in the Details section:
By default, 'ros' performs a log transformation prior to, and
after operations over the data.
Given those statements, perhaps the expectation should be a plot in
original units?
Keep in mind that a main purpose is summary statistics in the original
units.
After running the first example in ?ros, including the plot, try these:
unclass(myros)
abline(h=myros$modeled,col='blue')
