Hi everyone, I am Evelina and i have just joined the forum and hope to be able to support soembody as well as finding some help for my stats problem. I am trying to plot Frequencies against Densities of an ecological community using a Olmstead-Tukey diagram (O-T diagram). it is based on the Corner test for Association. I seem to undestand that the test can be run in R using the cor.test() function in the ade4 package, however it is not giving me what i expect, therefore it may be not the right function to use. Also, i would like to plot the data in a scatter plot with median for each variable, so that i have the 4 quadrants with frequent, dominant, ocasional and rare species. Could anyone help with some suggestions??? Many thanks in advance -- View this message in context: http://r.789695.n4.nabble.com/Olmstead-Tukey-Diagram-tp4647100.html Sent from the R help mailing list archive at Nabble.com.

Start by ditching Nabble and join and post from the r-help mailing list. Go to the CRAN website to do this. Many (most?) R-help participants do not use Nabble and will lose context in posts from it. Next, read and follow the posting guide. You have failed to follow its instructions to provide code and preferably data (via ?dput), so it will be difficult or impossible for people to divine what it is that you "expect." Asking good questions that people can help you with takes effort and skill, but it is common courtesy to save others wasted effort trying to figure out what you want. -- Bert
