Full_Name: Ross Boylan Version: 2.10.0 OS: Windows XP Submission from: (NULL) (198.144.201.14) Some of the help for setGeneric seems to have been garbled. In the section "Basic Use", 5th paragraph (where the example counts as a single line 3rd paragraph) it says <quote> Note that calling 'setGeneric()' in this form is not strictly necessary before calling

Recorded here so others may avoid my mistakes. I have a bunch of files containing fixed width data. The R Data guide suggests that one pre-process them with a script if they are large. They were 50MG and up, and I needed to process another file that gave the layout of the lines anyway. I tried rpy to not only preprocess but create the R data object in one go. It seemed like a good idea; it

I have a package that can use rmpi, but works fine without it. None of the automatic test code invokes rmpi functionality. (One test file illustrates how to use it, but has quit() as its first command.) What's the best way to handle this? In particular, what is the appropriate form for upload to CRAN? When I omitted rmpi from the DESCRITPION file R CMD check gave <quote> * checking

well, the next place to go, if fsck isn't enough would be to to try debugfs(1) man debugfs.

I seem to have run into https://bugzilla.redhat.com/show_bug.cgi?id=855640, because when I tried the fix/work-around at the end (comment 11), ethtool -K eth0 gro off, my download speed by speedtest went from undetectable to ~150Mb/s. However, it was not able to connect for the upload test, and so something may still be off. Non-virtual machines can do the upload test, so it's not just a

Originally I made a function yearStop that took an argument "object". I made a generic, but later changed the argument to "x". R keeps resurrecting the old definition. Could anyone explain what is going on, or how to fix it? Note particularly the end of the transcript below: I remove the generic, verify that the symbol is undefined, make a new function, and then make a

Is there any good source of information on how S4 classes (and methods) work from C? E.g., for reading how to read a slot value how to invoke a method how to test if you have an s4 object For writing, how to make a new instance of an S4 object. I've found scattered hints in the archive, including a link to a talk on this subject "I am using C code to create an S4 object based on

Apparently Scheme is clever and can turn certain apparently recursive function calls into into non-recursive evaluations. Does R do anything like that? I could find no reference to it in the language manual. What I'm wondering is whether there are desirable ways to express recursion in R. Thanks. -- Ross Boylan wk: (415) 514-8146 185 Berry St #5700

I'd like to evaluate a function at each point on a 2 or 3-D grid. Is there some function that already does this, or generates the grid of points? My search has led me to the grid and lattice packages, and I found a reference to the sp package (e.g., SpatialGrid) for this. There are things in there that might be relevant, but at first blush many of them are embedded in other concepts (grobs,

The cran2deb archives target testing. I just pulled a package from them onto a stable system; the library loaded but said > library(akima) Warning message: package 'akima' was built under R version 2.10.0 Are this and other packages likely to work correctly with different R's (2.7 in the case of stable)? How well are they likely to work with a backported R? The R version would

I have a small S4 class for which I've written a page grouping many of the accessors and replacement functions together. I would be interested in people comments on the approach I've taken. The code has a couple of decisions for which I could imagine alternatives. First, even simple get/set operations on class elements are wrapped in functions. I suppose I could just use myinstance at

It seems that if an S4 class has no slots it can't be instantiated because it is assumed to be virtual. Is there a way around this other than adding a do-nothing slot? A singleton would be OK, though is not essential. Problem: EmptyFitResult <- setClass("EmptyFitResult", representation=representation()) # also tried it without the second argument. same result. > e <-

I wonder if someone would confirm something I'm 99% sure of from the docs and discussion on the list, but can't find stated explicitly: R works only on problems that fit into (real or virtual) memory. Thus, even if you have a problem (e.g., simple regression) that could be solved by doing some operation on each row of a dataset at a time, you can't solve it unless the entire dataset

setClass("B", representation=representation("B", extra="numeric)) setClass("B", representation=representation(extra="numeric"), contains="B") Are these the same? If not, how do they differ? What about setClass("B", representation=representation("B", extra="numeric"), contains="B") ? As far as I can

Is there a way to control the aspect ratio of plots using ggplot? Specifically, I'm using the formula=a~b argument to produce a grid of plots, but the overall width of the result seems to vary for reasons that are obscure to me. This affects not only the appearance of the plots but the amount of space available for the title (which seems to be right justified relative to the right edge of the

I would like to define a function using symbols, but freeze the symbols at their current values at the time of definition. Both symbols referring to the global scope and symbols referring to arguments are at issue. Consider this (R 2.4.0): > k1 <- 5 > k [1] 100 > a <- function(z) function() z+k > a1 <- a(k1) > k1 <- 2 > k <- 3 > a1() [1] 5 > k <- 10 >

I haven't found much on S4 class redefinition; the little I've seen indicates the following is to be expected: 1. setClass("foo", ....) 2. create objects of class foo. 3. execute the same setClass("foo", ...) again (source the same file). 4. objects from step 2 are now NULL. Is that the expected behavior (I ran under R 2.7.1)? Assuming it is, it's kind of

On the Windows download page the second link is "Installation and other instructions" http://cran.cnr.berkeley.edu/bin/windows/base/README.R-3.1.2. Clicking on this gets me a "download or open as" dialogue rather than a page of text. I think something like this happened a few years ago, and the problem was the MIME type of the link. It would be nice to fix. Thanks. Ross
