Hi folks, I have a win2k acting as rsync client (I installed cwrsync) and FreeBSD 5.4 acting as rsync server and I'm having trouble with basic usage. ------------------------------ My /etc/rsyncd.conf: log file = /var/log/rsyncd.log pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock [antec_win2k_mike] path = /vol3/antec_win2k_mike uid = nobody gid = nobody read only

Dear R experts. I might be missing something obvious. I have been trying to fix this problem for some weeks. Please help. #data ped <- c(rep(1, 4), rep(2, 3), rep(3, 3)) y <- rnorm(10, 8, 2) # variable set 1 M1a <- sample (c(1, 2,3), 10, replace= T) M1b <- sample (c(1, 2,3), 10, replace= T) M1aP1 <- sample (c(1, 2,3), 10, replace= T) M1bP2 <- sample (c(1, 2,3), 10, replace= T)

hi i have a huge matrix and want to split it into 2. with the command %%2. but i get this warning message: *"Error in mmat%%2 : non-numeric argument to binary operator*" here's the bit from my matrix: V1 V2 [1,] "Affymetrix:CompositeSequence:ATH1-121501:244901_at" "2.653" [2,]

I have trouble documenting an R package. In my .Rd file (sixth line below), I have uhat<-m%*%y but when the package is built (successfully), the matrix multiplication part does not show up in the documentation. The line become (missing %*% y) uhat<-m === \examples{ x<-c(1,2,3,4,5) y<-c(1,1,2,2,4) x<-cbind(1,x) m<-mmat(x) uhat<-m%*%y dstat(uhat) } ?-- styen at ntu.edu.tw

Does R have a function like the S(plus) function, lmsreg, Least Median of Squares Regression? I am using R-0.61.

If I have two factors A and B with levels '1','2','3' and '1','4','6','8' recpectively (note the gaps in the second one). As factors, the levels are named as above while of course the internal codes are (1,2,3) and (1,2,3,4) respectively. I want to make a design matrix of these as one would in a linear model except I can't use lm or glm

I have written a wrapper for heatmap.2 called heatmap.w.row.and.col.clust which auto-generates breaks using breaks<-round((c(seq(from=(-20 * stddev), to=(20 * stddev))))/20, digits = 2) #(stddev in this case = 2.5) This has always worked well in the past but now I am getting an error that non-finite breaks are being generated. Drilling down, it seems that my wrapper is generating finite

This thread reveals that R has some holes in the solution of some of the linear algebra problems that may arise. It looks like Jim Ramsay used a quick and dirty approach to the generalized eigenproblem by using B^(-1) %*% A, which is usually not too successful due to issues with condition of B and making a symmetric/Hermitian problem unsymmetric. In short, the problem is stated as follows:
