Re: [R] Trend significant at p=0.05?

This is not the place for a statistical discussion; it *is* the place for R programming help. However, you seem to be confused about confidence intervals and significance, i.e. P values. You and others may wish to read about why the "magic" P = .05 significance level is a **bad idea**,

Nobody can help you without a lot more information, though there are some obvious places to start, like pre-allocating objects rather than growing them inside a loop. You can get a good discussion of how to profile your code here: http://adv-r.had.co.nz/Profiling.html Sarah On Mon, Mar 14, 2016

Re: [R] How to speed up R program

There's no way for anyone to be sure without looking directly at the code. As Jim said, the prime suspect is inefficient use of memory and excessive use of virtual memory. The book "Advanced R" by Hadley Wickham has a very detailed and easy to understand section on how to benchmark and

Hi Ragia, Improving the efficiency of a program usually requires detailed analysis of what it is doing and how those operations can be performed more rapidly. That is to say, without knowing what the program is supposed to accomplish and how it is doing it now, very little help can be provided.

No. 1.Avoid using the name "data" -- it's already a commonly used function in R. 2. Why do you want it to be a list instead of a vector? Is there a good reason for this? Consider: > d<- c(rep(0, 20), rep(1, 340)) > which(d>0)[1] [1] 21 3. If you haven't already done so, spend some time with
