[R] monte carlo simulations in permanova in vegan package

Dear colleagues, I am trying to run a PERMANOVA in the vegan package with an appropriate number of permutations (see example below), ideally . Obviously that number of permutations does not exists so I would like to use Monte Carlo permutation tests to derive the probability value, as is

Re: [R] monte carlo simulations in permanova in vegan package

I was therefore hoping there was a way of coding for the Monte-Carlo permutation procedure into adonis? Thanks for your help! From: stephen sefick [mailto:ssef...@gmail.com] Sent: 27 October 2015 03:11 PM To: Sean Porter Cc: r-help@r-project.org Subject: Re: [R] monte carlo simulations in perman

) This will extract the first 2 characters from the left. To extract 45 you would type: =Right(A1,2) To get 2 characters starting at position 4 you would type: =MID(A1, 4,2) Which will give you 23. Hope this helps. Regards, DR. SEAN PORTER Scientist South African Association for Marine

[R] randomForest warning: The response has five or fewer unique values. Are you sure you want to do regression?

Hello everyone, Im relatively new to R and new to the randomForest package and have scoured the archives for help with no luck. I am trying to perform a regression on a set of predictors and response variables to determine the most important predictors. I have 100 response variables collected
