Re: [Rd] Matlab Program to R

R rounds. Perhaps Matlab avoids doing so here. It's hard to say because your code is too long for anyone to read through. Maybe you could post a smaller reproducible example to pinpoint the result you see here. If you can do that, I think you may also find that the R-help mailing list is a better

[Rd] Shouldn't vector indexing with negative out-of-range index give an error?

In Section 'Indexing by vectors' of 'R Language Definition' (http://cran.r-project.org/doc/manuals/r-release/R-lang.html#Indexing-by-vectors) it says: "Integer. All elements of i must have the same sign. If they are positive, the elements of x with those index numbers are selected. If i contains n

[Rd] Why is the diag function so slow (for extraction)?

(I asked this question on StackOverflow a short time ago; sorry if you're seeing it again. Feel free to answer there as well if you like. The code formatting and such on that site can be nice.) I benchmarked matrix and vector subsetting to extract t

If your tests can be divided into multiple files in the tests/ directory then you will get lines like * checking tests ... Running ‘test1.R’ Running ‘test2.R’ Running ‘test3.R’ ... Paul On 05/04/2015 11:52 AM, Toby Hocking wrote: I am the author of R package animint which uses testthat f

No. I fixed that, the NAMESPACE file now contains: S3method("[[<-", mylist) S3method("$<-", mylist) It still does not work. I also created a print method (print.mylist) which did work out of the box, regardless of being in the NAMESPACE file or not. Could it be somehow in here (also in my NAMES

I really can't see it as a job for R to circumvent hare-brained sysadmin schemes like this You're not telling us who or what Travis is. I expect travis-ci.org has some clues, but in general, people on this list won't know. If it doesn't support setting parameters for the timeout, and it is

I am the author of R package animint which uses testthat for unit tests. This means that there is a single test file (animint/tests/testthat.R) and during R CMD check we will see the following output * checking tests ... Running ‘testthat.R’ I run these tests on Travis, which has a policy that i

[Rd] Problem with adding slots to S4 object

Dear all, I'm trying to create a virtual S4 class with some subclasses. I noticed that adding slots to this class increases the memory use and slows the functions down. Note that I'm adding very small slots (integer or character both of length 1). I've made a reproducible example at https://githu

[Rd] Define replacement functions

Hello I tried to define replacement functions for the class "mylist". When I test them in an active R session, they work -- however, when I put them into a package, they don't. Why and how to fix? make_my_list <- function( x, y ) { return(structure(list(x, y, class="mylist"))) } mylist
