Re: [R] change frequency of wind data correctly

Hi again, Didn't realize that the example didn't even span a full day. ssdf<-read.table(text="date_POSIX time_POSIX vmax 2018-02-01 00:00:00 27 2018-02-01 00:10:00 41 2018-02-01 00:20:00 46 2018-02-01 00:30:00 39 2018-02-01 00:40:00 34 2018-02-01 00:50:00 32 2018-02-01 01:00:00 37 2018-02-

Re: [R] change frequency of wind data correctly

Hi Stefano, I read in your date-time as two separate fields for convenience. You can split your single field at the space to get the same result. ssdf<-read.table(text="date_POSIX time_POSIX vmax 2018-02-01 00:00:00 27 2018-02-01 00:10:00 41 2018-02-01 00:20:00 46 2018-02-01 00:30:00 39 2018-

[R] change frequency of wind data correctly

Dear list users, I have wind data with frequency of 10 minutes (three years data). For simplicity let me use only max wind speed. I need to reduce the frequency to 30 minutes, at 00 (taking the mean of data at 40, 50 and 00 minutes) and at 30 (taking the mean of data at 10, 20 and 30 minutes)

Re: [R] RGB -> CYMK, with consistent colors

Martin, However after some testing. I totally agree that CMYK handling in R using pdf(..., colormodel = "cmyk") is not correct. Looking at the source code of the function PostScriptSetCol in file src/librarygrDevices/src/devPS.c the conversion to CMYK looks correct. Looking at the generated p

Current versions of Windows support user environment variables also, so having Administrator change the PATH should not be necessary. On December 2, 2020 7:20:16 AM PST, Duncan Murdoch wrote: >You are mixing up two different things. > >The .libPaths() function returns paths where R searches for

Re: [R] Add a third .libPath

You are mixing up two different things. The .libPaths() function returns paths where R searches for R packages. Rtools is not an R package, it is a collection of utilities and support files to run in Windows. For Rtools to be found, you need to add it to the Windows PATH variable, not to .li

Thank you Michael, But when we use the package, how to perform the test? library(ScottKnottESD) Can we do like sk <- sk_esd(svm, nn) to measure the effect size between the svm and nn ? On Wed, Dec 2, 2020 at 11:54 AM Michael Dewey wrote: > There seems to be a package on CRAN dedicated ex

There seems to be a package on CRAN dedicated exclusively to this test. It is called ScottKnotESD rather unoriginally. Michael. On 02/12/2020 10:32, Neha gupta wrote: I have the following data from resample svm= svm$resample$RMSE nn= nn$resample$RMSE we perform the statistical tests like wi
