Is there any way, in a LTspice plot, to _display_ the average

Mike Engelhardt has stated that he is philosophically opposed to
such imprecise functions. What is average? Is it an analog low
pass filter function or a numerical sliding average? [snip]
Simpson's Rule? Doesn't have corners or any of those other nasty analog limitations ;-)

Jim,
Yes, it does. Over what time interval? How many samples? Does every sample have equal weight? etc?
Rick
The time interval would be a user-specified parameter, as in PSpice's AVGX function in Probe (same as LTspice's plot window).
As for samples and "equal weight", you've never actually used Simpson's Rule have you ?:-) Back in the good old days it was used as an employments exam question... show the candidate a squiggly curve and ask him to compute the integral >:-}
