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 >

<<<snip>>> 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
