Bias in R's random integers?
Not sure what should happen theoretically for the code in vseq.c, but I see the same pattern with the R generators I tried (default, Super-Duper, and L'Ecuyer) and with with bash $RANDOM using N <- 10000 X1 <- replicate(N, as.integer(system("bash -c 'echo $RANDOM'", intern = TRUE))) X2 <- replicate(N, as.integer(system("bas...

Sequence from 2 Vectors
I would like to create a vector that is a sequence from 2 vectors. Could anyone provide suggestion on this? For example > a<-c(1,2,3) > b<-a+2 > b [1] 3 4 5 I would like to have a vector that is a sequence which starting from a and ending at b c = c(1:3,2:4,3:5) c = c(1,2,3,2,3,4,3,4,5) Thank you Best Regards, Suphajak Ngamlak Equity and Derivatives Trading Phatra Securities

Bias in R's random integers?
Hello, Top posting. Several people have asked about the code to replicate my results. I have cleaned up the code to remove an x/y coordinate bias for displaying the results directly on a 640 x 480 VGA adapter. You can find the code here: http://people.redhat.com/sgrubb/files/vseq.c To collect R samples: X <- runif(10000, min = 0, max = 65535) write.table(X, file = "~/r-rand.txt", sep = "\n", row.names = FALSE) Then: cat ~/r-rand.txt | ./vseq > ~/r-rand.csv And then to create the chart: library(ggplot2); num.csv <- read.csv("~/random.csv...

SIGBART/SIGSEGV while SELECTing virtual folder
Hello! I just installed Dovecot's latest nightly build (20081020) and tried the virtual folder features. I started with a really simple "all" folder: | # virtual/all | * | all But selecting this folder causes dovecot to panic (in most cases). While trying to debug this, I got slightly different results and I am not really sure yet if this is just non-deterministic, depends on
