I have a problem with the lapply function and I did not find any matching question posted earlier. I need to apply a permutation test to all list elements, however I am not able to setup the lapply correctly.
I am trying this
testperm <- lapply(test-list, FUN=perm.test, formula=(cover ~ group))
the function perm.test is from the package 'exactRankTests' cover is the dependent (numerical) variable and group is a factor.
Any hints on how to apply such a function would be very much appreciated. jens
