Dear R-experts,
Here below the reproducible example. I am trying to get the average of the 100 results
coming from the "lst" function. I have tried lst$mean and mean(lst). It does
not work.
Any help would be highly appreciated >

You need to spend some time with the Introduction to R that came with
your R installation. First, lst in your example is not a function, it
is a list. And as you found, the mean() function does not work on a
list. Second, your "minimal reproducible" example could have been
something like this
lst <- list()
for (i in 1:10) lst[i] <- i
mean(lst) # does not work
The documentation for mean, ?mean, says that it is looking for a numeric
or logical vector. To convert your list to a numeric vector you could
unlist() it.
mean(unlist(lst))
Hope this is helpful,
Dan
