I have a matrix named "spec" (see below), it is a 6x3 matrix, and each element of spec is a list. For example, spec[1,"wavenumber"] is a list, and it contains 1876 numeric numbers and NAs. I want to replace the NAs to zero, but don't know how to change it, the difficulty may be all the elements are of the class list, so it is hard to cha...

Hi all, I am having a problem using xyplot from lattice library. I am plotting one variable against another one, conditioning on two other variablesm one of which has 3 levels and the other 6 levels. The output is thus a 6x3 panel plot. Here's my code: print((xyplot(CloDurPercent[CloDurNA != 'NA' & Mscor<3.5]~ConsDur[CloDurNA != 'NA' & Mscor<3.5]|Pos*ConsId, data = Stops, pch = '.')) One of the panels is not plotting the data in it -- it remains blank. I first thought that I...

...matrix (N X N). By taking the first l columns of V, with gives a (l X l) matrix, i know that i than have a sub-space (R^L)of the original (R^M) space. I know that this sub-space basis is optimal in the least squares sense. The question is: given one 3-dim space generated by 6 vectors (A is a 6X3 matrix), i define a 2-dim orthonormal basis by taking the 2 first columns of V, how i can then project a new 3-dim vector in this 2-dim sub-space just defined?

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
