Re: [Rd] polypath winding rule with transparency

2016-08-02 Thread Michael Sumner
Hello, it's probably worth adding that this is not a problem with pathGrob, only polypath. This code is sufficient to demonstrate the problem in Windows. ## overlapping, both clock-wise x <- cbind(c(.1, .1, .6, .6, NA, .4, .4, .9, .9), c(.1, .6, .6, .1, NA, .4, .9, .9, .4)) ## only a p

Hi, I see different results in png() and pdf() for polypath() on Windows when using the "winding" rule ## overlapping, both clock-wise x <- cbind(c(.1, .1, .6, .6, NA, .4, .4, .9, .9), c(.1, .6, .6, .1, NA, .4, .9, .9, .4)) pfun <- function() { plot(x) polypath(x * 0.8 + 0.2, rule

[Rd] save/load + all.equal on reference class objects

2016-08-02 Thread Ben Bolker
After I save an object that contains reference class objects in some of its slots to a file and then re-load it, all.equal() seems to break for me. Is this a bug in all.equal, or is it likely caused by bad implementation of methods on my side? (I see that "'all.equal()' gains methods for 'envir

Hi Martin, John, Thanks for the responses! I've tidied up some of the notes from this mailing list thread and posted them on the bug tracker. John, in this case, I think namespaces are relevant because for non-exported S4 classes, the class information is made available through the '.__C__' symbo

Redirecting to R-devel I don't recall how long the SUGUSR handlers have been in R -- you can check in svn if you like -- it's been a long time. The intention is for them to serve as an emergency break -- a chance of possibly saving the workspace when you get stuck in an infinite loop in C/Fortran
