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

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.

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 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 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

Hello,   In R, How to read SPSS file and access the data item? Thank you. Regards, Suman Kundu [[alternative HTML version deleted]]

Hello, I would like to add to axis labels special caracters. Instead of writing :plot(simul, xlab="beta", ylab="sigma11") It would be great if I could write something as in LaTeX :plot(simul, xlab="\beta", ylab="\sigma_{11}") Is there a way to do that ?
