Okay, been working with tripack, seems the most mature package for this. Got it to work well with their test data set - data(tritest). When i tried random numbers to explore further, i am getting some results that don't reconcile. example run this: library(tripack) y <- runif(100) x <- runif(100) vm <- voronoi.mosaic(x,y) plot(vm) par(new=T) plot(x,y,col='blue') when

Hello, trying to locate all the string commands in the base version of R, can't seem to find an area that describes them. I am in need to do some serious parsing of text data to create my dataset. Is there a summary link to all the character operators? string manipulations that would help in parsing text.

Hello, we are needing to generate optimal (Fractional) designs for discrete choice applications, where we will be using logistic regression or multinomial logit as the modeling technique. It looks like optFederov, in the AlgDesign package may work, but not sure if this algorithm works when the variable of interest is binary or nominal? Anyone who are experts in this area, anyone interested

Hello, does R estimate belief networks to estimate chains of causality. Anyone point me to the right direction, or the most developed library? looking at DEAL>

Hello, writing some R code to cleanse a data set, if the following set of symbols are identified then perform some actions. trying to write the minimum code to do this. tname = "VIX" checkticker = c("VIX", "TYX", "TNX", "IRX") if (tname == checkticker) { //perform some operations } result i get is > tname == checkticker

Hello, not understanding the output of prcomp, I reduce the number of components and the output continues to show cumulative 100% of the variance explained, which can't be the case dropping from 8 components to 3. How do i get the output in terms of the cumulative % of the total variance, so when i go from total solution of 8 (8 variables in the data set), to a reduced number of

Hello, we are writing rich internet user interfaces and like to call R for some of the computational needs on the data, as well as some creation of image files. Our objects communicate via the SOAP interface. We have been researching the various packages to expose R as a SOAP service. No current CRAN SOAP packages however. Found 3 to date: RSOAP (http://sourceforge.net/projects/rsoap/)

hello, i just got introduced to R - WOW its beautiful.. I am presently a SAS user and wanted to configure R to work in a multi-user enteprise environment. Client - Server. Where we have a strong LINUX server supporting about 10 statisticians with R. Anyone have any backround or information they can share to help me get jump-started on setting up R in this environment? Does each user have

Hello, does anyone know of any R routines capable of whats called Hierarchical Forecasting, reconciling the different hierarchies. Example: A top down forecast where the corporate forecast is created and then all the regions within the corporate entity are also forecasted, with the constraint they sum to the corporate forecast.

Hello, running a mixed model in the package LME4, lmer() Panel data, have about 322 time periods and 50 states, total data set is approx 15K records and about 20 explanatory variables. Not a very large data set. We run random intercepts as well as random coefficients for about 10 of the variables, the rest come in as fixed effects. We are running into a wall of time to execute these models.

LLVMers, We have completed the move to the new server for LLVM.org. One casualty of this move was that svn.llvm.org was NOT enabled at this time. There is a new certificate for LLVM.org and HTTPS is enabled for the website. We know of a few issues with some of the webpages but will be working them out over the next few days. Please do not hesitate to contact llvm-admin at lists.llvm.org with

Are the videos another casualty of the server move? Following the links down to a video to here: http://llvm.org/devmtg/2014-10/Videos/Adding%20and%20Optimizing%20a%20Subtarget%20for%20MIScheduler-720.mov Sends me to a dead link. Do we know when this is expected to work again? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, I am trying to count IR instructions in a function for static analysis using llvm pass. In contrast with existing examples, I am trying to include instruction counts of all the callees of the function. Counting the instructions of a function is easy using passes, but iterating through the module's CallGraph is proving to be confusing. I believe I have to use CallGraphWrapperPass to

Thanks so much John! That works :) Previously I wrote a pass that inherited from CallGraphWrapperPass and used its getCallGraph() function within runOnModule() which resulted in segmentation faults for me. Not sure why that happened, perhaps callgraph wasn't setup by the time runOnModule() was called internally. If you know why, kindly enlighten me and perhaps document the behavior for the

Hi, I am trying to download some data using read.csv and it works perfectly in RStudio and fails in the R console in the terminal in Ubuntu 18.04 after upgrading from R 3.6.3 to 4.0.2. Before upgrading this worked in the R console in the terminal also without any issues. Why would that be? How to fix this? Below please find R code output and sessionInfo(). *Works in RStudio* >

Hello, we are receiving some data, sample below - with a weird time/date stamp format, we need some help with R on converting this time date stamp to a useable field in R, date and time in a data-frame. The developer says its the number of milliseconds since midnight, January 1, 1970. sample: *1232558018624* --------------------- How do I interpret the time stamp? Is there a date, i need

My understand is that in DAG terminology, Flag is now called Glue. It would be nice for someone to go through and clean up the code as far as comments and variable names. That was driving me close to the brink of insanity till I found out about this. Even in Selection Dag Node Properties def SDNPOutGlue : SDNodeProperty; // Write a flag result def SDNPInGlue : SDNodeProperty;

A general problem i run into, i know there must be a simple solution. I like to create a variable by appending a 1 for example, (i need to loop later on from 1 to X, thus the reason for this). So i assign the variable vplot with this value, however it has quotes and when i use it in a barplot, it throws an error. but the tcenter$X1 does exist, its an element of a data frame. So if i type
