[R] vector matching
Hello all, I have searched the archives for a similar problem to no avail. I could use your help. I have a bunch of vectors organized into two matrices, x and y. These vectors (as rows) consist of combinations of elements such that order does not matter. I want to create a third matrix from the first two, which is basically all the rows in x and all the rows in y, excluding the rows that they both have in common. %in% seems to match individual elements, not entire rows, so something else is needed. Any help is appreciated. Thanks, -Michael -- Michael A. Nestrud Cornell U.

[R] teaching R
Hello all, I am going to be running a small statistics workshop using R sometime in November. I am restricted to R because of the specific libraries I will be using - a good thing in my book - however the attendees are unfamiliar with R. I plan on giving as little R information as possible - just what is absolute necessary to run the statistics (the workshop is short, no time to spend hours teaching R). Has anyone done anything like this? Are there any public powerpoint/pdfs/etc. available for this type of application? Any advice / what works / what doesn't work is appreciated for those that have tried this before me. Sincerely, -Michael -- Michael A. Nestrud Cornell U.
