Hi! I wonder if anyone has experiences of calling other programs from R (i.e., not C or Fortran programs). Specifically I want to call LEM from R and execute it in a loop to process its output in R. Thanks, Tim Liao

..., R shows the error called 'singular gradient' in the model. Could anyone please help me to fix the error? I don't think there are any problems with my data because I can fit the same model to 2004 data without any problems using SAS. Thank you very much in advance.

Dear Matthieu or other friends, I want to select two unknown thresholds with the following function: grid<- selectSETAR(x1, m=1, thDelay=0, criterion=C("AIC","SSR"), nthresh=2) print(grid) plot(grid) where x1 is a price time series. However, it always shows the following error. Error in selectSETAR(x1, m = 1, thDelay = 0, criterion = C("AIC",

I am excited to learn that Prof. Tierney is bringing to us compiled R. I would like to learn when it will be available. This information will be useful in scheduling some of my projects. Thanks.

Hi, So I finally have time to test the u2f support but so far I haven't been very successful, Specifically, current HEAD has SSH_SK_VERSION_MAJOR 0x00040000 and I can't seem to find a matching libfido2 version, current HEAD of Yubico/libfido2 is 0x00020000 Is there a more up to date libfido2 or a particular commit of openssh-portable I should be using? thanks Sean

...eliminating all the apply(). It turns out that apply is slow, is slower than direct loop, it is an order slower than a matrix operation alternative. Here is one example. The first apply version runs 19 seconds, the second loop version runs 13 seconds, the third matrix version runs 1 second. Jason Liao rm(list=ls(all=TRUE)) test1 <- function() { u <- runif(n*m); dim(u) <- c(n,m); v <- apply(u, 2, crossprod); } test2 <- function() { u <- runif(n*m); dim(u) <- c(n,m); v <- numeric(m); for(j in 1:m) v[j] <- crossprod(u[, j]); }...

I have been comparing R with other languages and systems. One peculiar feature of R is there is no scalar. Instead, it is just a vector of length one. I wondered how much performance penalty this deign cause, particular in situations with many scalars in a program. Thanks.
