Kevin, Maybe also look at what air quality monitoring is being done in area. https://cran.r-project.org/web/packages/RAQSAPI/vignettes/RAQSAPIvignette.html Depends what and how near, but might be something relevant there?

Hi all, I am still battling to get browsing across subnets to work. I just need some clarification on some issues. I understand the following things to be the case, please correct me if I am wrong: - Machines on a subnet will periodically announce their existance by broadcasting to everyone their identity - Other machines will hear these broadcasts, and add the machines to their browse lists. -

This is not a request for help, but I thought the readers of this mailing list might appreciate the following, anyway. I have been working with US EPA's (that's the United States Environmental Protection Agency) Office of Pesticides on a preliminary assessment for the effects of exposure to multiple organophosphate pesticides on human health (as required by the Food Quality Protection

SUMMARY: Specific problem: I'm regridding biomass-burning emissions from a global/unprojected inventory to a regional projection (LCC over North America). I need to have boundaries for Canada, Mexico, and US (including US states), but also Caribbean and Atlantic nations (notably the Bahamas). I would also like to add Canadian provinces and Mexican states. How to put these together? General

Hello, I was interested in trying to write an R script to calculate a UCL for a lognormal distribution using the Chebyshev Inequality — MVUE Approach (based on EPA’s guidance found in http://www.epa.gov/oswer/riskassessment/pdf/ucl.pdf). This looks like it should be straight forward, but I am need to calculate an MVUE for the population mean and an MVUE for the population variance, which requires

I am beginning a much-delayed update of odesolve to include several ordinary differential equation solvers from the Livermore package ODEPACK. These are much-used and reliable Fortran codes, and I plan (as I did for lsoda in the current odesolve package) to make as few changes as possible to the Fortran 77 code. However, recently someone wanted to make nested calls to lsoda, which will not work,

I am experimenting with exporting pointers to some of the functions in deSolve so that other packages may import them, using the 'R_RegisterCCallable' mechanism. I have added a header file and some other C code in inst/include of the deSolve source package that need to be accessible to other packages. I have a site-library set up in Rprofile.site where all installed packages go, and as

I'm trying to get R to simulate the sum of the values on 10 fair dice (yes, it's related to a homework problem, but is not the problem itself). I tried to do this: > rep(sum(sample(1:6,100,replace=T)), times=10) [1] 341 341 341 341 341 341 341 341 341 341 and noticed that sum(sample()) seems to be only evaluated once. How can I overcome this, so that I get a vector of values that

I help to coordinate the USEPA's R user group. We have over 500 members and our security officer has required us to update to R version 4.4.0 because of the security vulnerability to versions prior. However, we cannot download the patched version because it does not have a signed certificate and Microsoft Defender won't allow us to install it. Most of our users rely on the RStudio

I'm trying to replicate some of the examples from my textbook in R (my text uses Minitab).

I've written an application that uses the tcltk package, and have distributed it to a few people to use here in the Agency on Windows 98 machines. It has worked just fine on all but one of those machines. On that one (system information quoted below), we persist in getting the error message: > require (tcltk) Loading required package: tcltk Error in dyn.load(x, as.logical(local),

I'm trying to get R, Sweave, ESS and XEmacs or emacs all installed and working together on my Windows XP Pro system. I've got R 2.6.0 working just fine, installed from the R Windows installer. I also have CYGWIN_NT-5.1 with XEmacs 21.4 working okay. Can anyone point me to any documentation on how to bring these together so that R code typed in Xemacs can be run in R? I found the ESS

I'm trying to learn statistics and R at the same time. I have an undergraduate science degree and one year of calculus (30 years ago), but never took a stats course. I hope to take some stats courses in the next year, but thought I would start to see how much I could teach myself. I work for an organization that analyses behavior change communication programs regarding HIV/AIDS and
