Will lustre-1.5.95 build with 2.6.18-vanilla kernel? Which_patch doesn''t contain this kernel but I could see them in the series files. Do somebody have experience in building the same? I tried to do it but lot of errors after applying the patches in 2.6.18-vanilla series. Thanks, Venkat

Hi, I wanted to know how to compute the correlation ratio (eta) between two variables using R. Is there any function to compute the correlation ratio. Any help will be very much appreciated. Thanks, Suman [[alternative HTML version deleted]]

Hello All, I wanted to do many plots (in my case, wanted to get 6 histograms) on the same figure. Is there a method in R that analogous to 'subplot' in MATLAB? Any help will be very much appreciated. thanks, Suman [[alternative HTML version deleted]]

Hello, I have a dataset with 20,000 variables.and I would like to compute a pearson correlation matrix which will be 20000*20000. The cor() function doesnt work in this case due to memory problem. If you have any ideas regarding a feasible way to compute correlations on such a huge dataset, please help me out. Please feel free to share your memory handling techniques in R. Thanks, Suman

Hello, I have a big matrix of size (20,5) -bmat . I have to loop though the rows in the matrix and create DIFFERENT matrices each time I go through the loop. counts=c(4,6,10); p=1; for (i in 1:length(counts)) { smat=bmat[p:p+i-1,]; p=p+i; } The problem is smat overwrites itself each time inside the loop. I would like to have smat1, smat2, smat3 instead of a single vector smat.

Hello, This might be a very basic question but I was not sure how to go about it. I just wanted to calcluate the time it takes to run my program. Basically I was to put a timer at the start and the end of the program in order to see how much time it takes to give the output (similar to tic-tac in MATLAB) . Any help will be appreciated.

I need help with calculating lsmeans (adjusted means) of different terms in a linear model including the main effect and the interaction effect terms. I use lm to run the linear models...I previously noted from literature that that "effects" package can be used to generate lsmeans. But I tried to use it but could not figure out which option to use to get means. If anyone can give an

Hi there, I have a Dell T3400 Workstation with CentOS5.1 as dom0. I have hidden a network interface in dom0 to pass it to domU. The domU can come up with the NIC when it''s OS is CentOS5.1 or RHEL5. But when it comes to RedHat4.5 , the NIC can not be found. As I type the command "lspci" in RHEL4.5 domU, it returned: pcilib: Cannot open /proc/bus/pci

Hello, I wanted to know how to plot a histogram using a vector of frequencies rather than the data vector as a whole. So I have two vectors: a vector of labels V1= c("A","B","C","D") and vector B which is a vector of frequencies of A, B, C and D respectively V2=c(20,50,60,30). I wanted to plot a histogram of the labels using the frequencies. I could not
