[LLVMdev] LLVM and "who does delete"
Hi, I am new to LLVM, and I am pretty much paranoid about loose pointers. I would like to write a compiler in C++ + boost + llvm, but am worried about the pointers created and passed as parameters, especially about whose responsibility it is of deallocating them (does the LLVM API do it internally, or is it the application programmer's responsibility?). And what is the best practice for

roc plot with zero length labels error
I am trying to create the roc plot bootstrap method from library(verification), and when I set the plot =both or emp then I get the following error. The roc.plot works fine when the plot is set to binorm. This is my first time using this function in R and am not sure what this error means or how to resolve the issue. It seems to work ok with the example dataset. Is there an option or data

Random Number Testing...
Hi, Suppose I want to test a set of random numbers (using the Binormal random number generator), input the following command to generate a set of random numbers: test <- rbinom( 10000000, 1, 0.5 ) How can I, after obtaining the result, export the vector "test" into an text file? Then, suppose I want to do something like: > x <- 1e10 > x [1] 1e+10

client connection errors: SSL, SNI and DNS_ALT_NAMES Oh My
Hi All, I''ve run into a bit of a tangle. I currently have two puppet masters which are "load balanced" with round robin DNS (one is also the CA). I''m using dns_alt_names to let them each answer to puppet.my.domain.com For the past year this has been fine. About a week ago I tried to add a third & while all my Linux clients are happy with the new arrangement,

question on the ellipse package
Hi all, I'm intersted in draw confidence regions for two estimates that *are not* in the same GLM, but I know their point estimates c(a,b) and their covariance matrix V, say. Of course > V[1,2]==V[2,1] [1] TRUE Their joint distribution is not binormal (at least i don't know it), but I know (or I assume) their limiting distribution is Normal, so I can use the bivariate Wald statistics to

multivariate ordered probit regression---use standard bivariate normal distribution?
Hello. I have yet to receive a response to my previous post, so I may have done a poor job asking the question. So, here is the general question: how can I run a run a multivariate (more than one non-independent, response variables) ordered probit regression model? I've had success doing this in the univariate case using the vglm() function in the VGAM package. For example:

R question
Hi, Would you help me solve the following question? Thanks. Question: If I try to set the probability=0.05 and find the approximate x. (The answer should be somewhere between 2.1782 and 2.1783.)

Jagged ROC curves?
Hi Brian, Your underlying dataset for the ROC curve only has 4 unique values for specificity, even though there are 23 elements in the vector, hence the step function nature of the first plot. The default smoothing in the smooth() function is "binormal". You might try one of the other smoothing options to see the result and whether they make visual sense. In the absence of smoothing,

pmvnorm?
Dear all, The MASS library provides a mvrnorm function to generate random numbers from a multivariate normal distribution, similar to S-Plus's rmvnorm, but is there an R-equivalent to pmvnorm, which generates probabilities from a multivariate normal?

Issues with 'Miwa' algorithm in mvtnorm package
Currently doing some work on local maxima on a random field and have encountered an issue with the Miwa algorithm used with the pmvnorm function in the mvtnorm R package. Based on recommendations by Mi et al., we ran the mvtnorm package using the Miwa algorithm, since we have a maximum of 4 dimensions with non-singular matrices. However, running the estimation procedure in this way, we obtained
