how to draw manifold?
Hi, I need some help either in how to configure variables for wireframe(), or some suggestions as to other graphics commands to use for plotting a 2-D manifold in 3-D space. Here is an example I tried (in the hopes that it would plot a helical line) : xsp<-matrix(c(cos(seq(0,80)/5)),9,9) ysp<-matrix(c(sin(seq(0,80)/5)),9,9) zsp<-matrix(c((seq(0,80)/20)),9,9) wireframe(zsp~xsp*ysp)

comparing and combing files
Hello, I have two tab-delimited files which I would like to combine. In the first one I have gene IDs (Unique) on column 1 and than various experimental results from microarray analysis (see attached files list1 ) the second arrays have the same genes IDs (more and in a different order, some are double) (see attached files list2 ) What I would like to do is to search in the second list for gene

Optimization in R
Hi all, I've been working on improving R's optim() command, which does general purpose unconstrained optimization. Obviously, this is important for many statistics computations, such as maximum likelihood, method of moments, etc. I have focused my efforts of the BFGS method, mainly because it best matches my current projects. Here's a quick summary of what I've done: *

strange misflagging of incoming mail as trash
Setting up postfix/dovecot on a clean FreeBSD cloud server, and have discovered a strange problem resulting from the interaction of Mac OS X Mail and dovecot (using the Maildir file structure). Essentially, under very specific circumstances, Mail somehow tells dovecot that a new incoming message is trash, dovecot marks it as such, and the message effectively vanishes. The specific circumstance is

Plotting parametrized curves (2D or 3D)
The curve() function plots an expression in x over an interval [from,to]. I am looking for a function that would allow me to plot a parametrized curve t -> x(t) where x is a vector in 2 or 3 dimensions. For example (cos(t), sin(t)) (a2D  circle) or (cos(t), sin(t), t) (a 3D helix). It seems that neither curve(), plot(), nor persp() are helpful for that particular problem. I bet I?m not the

recommneded tape drives
Hi there, I am pricing out a dell 840 (low end file server) that will run latest centos. Can anyone recommend a good tape drive/card combo with centos? The drives (to be backed up) in it will be a raid 0 - 500gb. Thanks in advance! Dustin
