Hi Emilien,

sorry, the function for ordination in JUICE recently doesn't work - I haven't compile ordijuice library for latest R versions yet. It should work for R version 2.9 - 2.13, but not newer.

About vegan package - this may happen if you update vegan library from JUICE and at the same time you had R opened and vegan loaded in R - this action would break the installation of vegan library. Anyway, what you could do is - go to Program Files/R/R-X.X.X/library and manually delete vegan folder with everything inside. Open JUICE again and update libraries - it should install the new version of vegan. But again - you need to use R version 2.13 or older. Hope this helps, otherwise let me know.

The reason I haven't update ordijuice library is that we found that this way how ordinations are done in JUICE is not stable - it often simply doesn't work, and it's not easy to find a reason. We introduced new way how analyze data from JUICE in R - it's called JUICE-R, see the http://www.bit.ly/juice-r website. I hope, somewhen soon, to produce JUICE-R script for ordinations, which would replace the function in JUICE while keeping the same functionality. Just needs time :)

Regards

David

Hi there, I'd love to use PCA analysis but after having downloaded everything : R last version, scripts..., a message box appears. It's written : "The package VEGAN is used or was installed incorrectly. Please update it once more". Any hints for troubleshooting ? In advance, thanks a lot for your answer.
