Dear all, I have an error in the simple prediction function for lm(). Maybe someone experienced the same? xma <- matrix(data = 0, nrow = 100, ncol = 2) xma[, 1] <- rnorm(100) xma[, 2] <- rchisq(100, df = 3) m1 <- lm(xma[, 1] ~ xma[, 2]) predict(m1, as.data.frame(seq(-13, 13, 0.5))) Thanks a lot, Trafim [[alternative HTML version deleted]]

...ve size-extending multiplication, for which your statement is not true: - Motorola MC68K has i16 x 16 -> i32 instructions in signed and unsigned forms - Itanium has signed and unsigned multiplications with i64 x i64 -> i64 where you can take the high or low part of the resulting i128. While xma.lu is a pseudo-op since it's the same as xma.lu, xma.hu and xma.h (unsigned and signed) are distinct. I'm pretty sure there are other similar architectures. Regards Christophe

Hi, my target handles operands of multiplying instructions differently based on signedness. I wonder then how I would do instruction selection based on the operands signs? The mul instruction sets a nsw for signed, but when i try unsigned ops, there is no wrap flag at all. I'm not sure this is enough information to work with, or?

Hi Jonas, > my target handles operands of multiplying instructions differently based on > signedness. since the result of a multiply doesn't depend on the signedness, I find it strange that your target differentiates between them. What I'm saying is that if you have (say) two i32 numbers a and b and you do a signed multiply: c = a *s b and an unsigned multiply d = a *u b

I am landing here again following a spell on the list when I worked at XMA in the UK. Hello again. I have a use case of having a remote office, which should be able to have a common storage area with a main office. At the last company I worked with, we used GPFS with AFM to achieve this (not really relevant to this list). I at first though Geo Replication would be id...

I wrote a function to calculate cosine distances between rows of a matrix. It uses two loops and is slow. Any suggestions to speed this up? Thanks in advance. theta.dist <- function(x){ res <- matrix(NA, nrow(x), nrow(x)) for (i in 1:nrow(x)){ for(j in 1:nrow(x)){ if (i > j) res[i, j] <- res[j, i] else { v1 <- x[i,] v2 <- x[j,]

Hi, I have a problem in which I have test score data on students from a number of schools. In each school I have a measure of whether or not they received special programming. I am interested in the interaction between school and attendance to the programming, but in a very select set of comparisons. I'd like to cast the test as one in which students in each school who attend are

Hello list ! Today i ran yum update on my corporate server thta runs fedoara core 5. All went well but i stumbled on the samba update... My network setup is as follows.. I have a small office network, no domain controller and such. The setup uses user authentication, and all shares are devided into departments, each defined group is a department, the groups cannot access/browse eachothers

Using the heatmap function in mva, it seems to be hard to use different colors in the edges leading to different groups of objects, as commonly done in many heatmaps in the microarray graphics. Any suggestions? Thanks. max
