...obust against changes in the column numbers of the x matrix. That is why I am telling R to look up the number of rows and columns in the x matrix when constructing the y matrix, rather than just putting in a hard count for the number of rows and columns in the y matrix.

...ith the syntax? If I fit the model using the stats library, the code looks like this: model <- glm(x$trait ~ x$PC1 + I((x$PC1)^2) + I((x$PC1)^3), family = binomial) What would be the equivalent syntax for the lrm function?

...I don't know how to do it: mtext("?", side = 1, line = 0, at = 7) #that question mark is a place-holder for the arrow. How do I put an up-arrow there instead of the question mark -- as large as possible?

I don't have any there; I suppose that is the problem. I did a locate *.xslt and nothing pertaining to icecast came up. I suppose I should grab the source and check it out. I installed from the rpm.

I have found lots of people talking about this problem, however I have yet to come across a solution. None of the OS X 10.4.x systems can write to a Samba share on a RH 7.3 server with Samba "Version 2.2.7-security-rollup-fix" Windows and Linux can read and write with no problems. All systems can write to a samba 3 server running RHEL 4, I've compared smb.conf files and
