I am not up on the internals of R but there does seem some run for parallelism. Are we talking about special hardware? or running this on an Intel Box? If it is the second, then I am thinking threads would be the way to go. Please consider the following R statements: for( i in 1:30 )a[i

Re: [R] How to speed up my program

Hi Ragia, First, when you wrote mad, I assume you mean made. Also, when you say it is a multi core prog, does that mean it is using threads? running two or more items in parallel? By any chance are you using this package? https://stat.ethz.ch/R-manual/R-devel/library/parallel/doc/parallel.pdf

Re: [R] for loop in R

I only see one for loop in your code. I am wondering if you want a second for loop based upon the length of newdata. I would also think that you do not need the second call to set.seed. Bob On 1/12/2017 4:44 PM, Jennifer Sheng wrote: Dear friends, I am working on a double loop using for. On

Here is one thought. Assign each month a value of 0, 1 or 2. Then do a simple linear regression analysis where the value of the month is the independent variable. You can also do multiple linear regression with the value you assigned to the month plus the other factors that you believe are causin

Quite nice Jim. A little par() magic, some well thought plot window dimensions, and good to go. I wasn't looking, but now that I've seen it, I can imagine uses. Bruce - see also https://cran.r-project.org/web/packages/xtable/vignettes/xtableGallery.pdf On 3/26/2017 4:28 PM, Jim Lemon wrote:
