R memory limits on table(x, y) (and bigtabulate)
Sorry, don't know enough to give you trustworthy answers, but I can say that crashes due to (or linked to) packages should usually be reported to the package maintainer, who can be found by the ?maintainer function. That person may not monitor this list. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it."

Question about tables in bigtabulate
I have a large file backed big. matrix, with millions of rows and 20 columns. The columns contain data that I simply need to tabulate. There are a few dozen unique values. and I just want a frequency count Test code with a small "big" matrix. library(bigmemory) library(bigtabulate) test <- big.matrix(nrow = 100, ncol = 10) test[,1:3]<- sample(150) test[,4:6]<-

Failing to print mer object in an RData image
Hi all I have problems in accessing a mer object called model.01 from a workspace that was created with R 2.8.1 and saved with save into an .RData file (on Windows XP or Ubuntu 8.10, don't remember anymore). Now I want to open it in R 2.9.0 on Ubuntu 8.10. I use # load workspace load("name.RData") which seems to work: ls() # all objects in there [1] "all"

tapply for enormous (>2^31 row) matrices
Hi all, SETUP: I have pairwise data on 22 chromosomes. Data matrix X for a given chromosome looks like this: 1 13 58 1.12 6 142 56 1.11 18 307 64 3.13 22 320 58 0.72 Where column 1 is person ID 1, column 2 is person ID 2, column 3 can be ignored, and column 4 is how much chromosomal sharing those two individuals have in some small portion of the chromosome. There are 9000 individual people, and

Fast update of a lot of records in a database?
We have a PostgreSQL table with about 400000 records in it. Using either RODBC or RdbiPgSQL, what is the fastest way to update one (or a few) column(s) in a large collection of records? Currently we're sending sql like BEGIN UPDATE table SET col1=value WHERE id=id (repeated thousands of times for different ids) COMMIT and this takes hours to complete. Surely there must be a quicker

clustering problem
Hi, I have a gene expression experiment with 20 samples and 25000 genes each. I'd like to perform clustering on these. It turned out to become much faster when I transform the underlying matrix with t(matrix). Unfortunately then I'm not anymore able to use cutree to access individual clusters. In general I do something like this: hc <- hclust(dist(USArrests), "ave")

Crash using exceptions
Hello, I get a crash in my program that uses exceptions and the LLVM JIT, even though the exceptions are controlled and thrown/catched in a part that doesn't deal with LLVM. I noticed that llvm-config --cxxflags includes the -fno-exceptions flag. Do I need to throw no exceptions whatsoever in my application to use LLVM JIT? As a minimal example, I modified the code in

Dumb question: do you have a restrictive ulimit setting that might cause the tblgen program to run out of memory?

R-devel does not update the C++ returned variables
Thanks! I went through the online posts which supports the power of .Call over .C. But my probably naive question is why does this work for my code with R but not R-devel? And another question is related to using .Call. Based on the manual page, I do not need to change the function parameters when using .Call. So I can run like this: .Call("sppedUp", D, S, pD, pS, nrow(D), as.integer(N),

anova comparisons
I have several linear models on the same data: m1 <- lm(y ~ poly(x,1)) m2 <- lm(y ~ poly(x,2)) m3 <- lm(y ~ poly(x,3)) What I don't understand is why anova(m1, m2, m3, test="F") - yields the same RSS and SS values, but a different p-value from anova(m1, m2, test="F") - when it also yields the SAME as anova(m2, m3, test="F") What am I missing?
