[R] R rounding problem?

Hello, I made a mistake today on simple counting in R, that almost got me into trouble. After trying multiple times, I finally figured out it's rounding issue in R. For exmaple, when I just simply type: > (6.9-6.3) > 0.6 [1] TRUE 6.9-6.3 should be 0.6 exactly, but R thinks that it's greater t

Hi Ahmet, I really can't work out what your problem is. I don't have access to the data you are using and so cannot inspect "a" to see what might be in it. Jim On Wed, Sep 2, 2020 at 8:54 AM ahmet varlı wrote: > > Hi jim, > > > > I have a new question. I have 71 years raster data from 1949 to 20

Re: [R] Assigning cores

The big question is whether each worker or thread uses parallel processing itself, or whether it uses resources like cache in which case 20 threads fighting over the cache would slow you down substantially. If your simulations use operations implemented in BLAS or LAPACK, be aware that some R insta

Re: [R] Assigning cores

Do you have 20 actual cores or 10 cores/20 threads? detectCores() doesn't usually know the difference but the CPU may be too busy accessing memory to let that last thread get any useful work done. I often find that allocating real cores is more practical than thinking in terms of thread so try a

[R] calculating linear regression for each word cell

Hi all, I have 71 raster for each year. I am trying to convert all raster layer to 1 array (94 ,192 , 71) and then � would calculate for each word cell a linear regression that shows the change but i dont know how � can do this For creating array with rasters between 1949 and 2019 library(r

Re: [R] Assigning cores

Hi Leslie and all. You may want to investigate using SparklyR on a cloud environment like AWS, where you have more packages that are designed to work on cluster computing environments and you have more control over those types of parallel operations. V/r, Tom W. Quoting Leslie Rutkows

[R] Assigning cores

Hi all, I'm working on a large simulation and I'm using the doParallel package to parallelize my work. I have 20 cores on my machine and would like to preserve some for day-to-day activities - word processing, sending emails, etc. I started by saving 1 core and it was clear that *everything* was
