similar to: Overwrite S3 methond from base package

Dear all, Today I figured out that there is a neat function called droplevels, which, well, drops unused levels in a data frame. I tried the function with some of my data sets and it turned out that not only the unused levels were dropped but also the contrasts I set via "C". I had a look into the code, and this behaviour arises from the fact that droplevels uses simply factor to drop

Hi, from the man page ?methods, I expected to be able to build pairs (class,package) for a given S3 method, e.g., print, using attr(methods(print), 'info'). However all the methods, except the ones defined in base or S4 methods, get the 'from' value "registered S3method for print", instead of the actual package name (see below for the first rows). Is this normal

I have updated the rms package to extensively use NAMESPACE. I cannot get certain S3 methods to dispatch. For example I have in NAMESPACE S3method(anova, rms) S3method(latex, anova.rms) anova.rms produces an object of class "anova.rms" and there is a latex.anova.rms function in rms. But when I do latex(anova(fit)) I get an invocation of latex.default. I have tried using

Hi all, The profr package provides a method for displaying its output with ggplot: ggplot.print. You don't need this ggplot2 to use profr, so ggplot2 is listed under enhances in the DESCRIPTION file. If I have just S3method(ggplot, profr) in my NAMESPACE, then I get: ** testing if installed package can be loaded Error : object 'ggplot' not found whilst loading namespace

PkgA wishes to write a method for 'unique' on S4 class 'A'. ?Methods indicates that one should setGeneric("unique") setClass("A") unique.A <- function(x, incomparables=FALSE, ...) {} setMethod(unique, "A", unique.A) Both S3 and S4 methods need to be exported in the NAMESPACE import(methods) S3method(unique, A)

The last line of the example in droplevels' manual page seems to be incorrect to me. I think it should read: "table(droplevels(aq$Month))". Amazingly (I don't understand) both variants seem to produce the same result (R 3.3.3): --- > aq <- transform(airquality, Month = factor(Month, labels = month.abb[5:9])) > aq <- subset(aq, Month != "Jul") >

R-exts.pdf discribes S3method a little bit. But I want to understand more on how it is called, implemented and when to use it. I don't find it in an R session. But I see S3method() in some NAMESPACE files. > S3method Error: object 'S3method' not found > ?S3method No documentation for 'S3method' in specified packages and libraries: you could try '??S3method' I

I am writing my first R package, and I have been getting the following series of errors when I run R CMD check: * checking S3 generic/method consistency ...

Dear List, In one of my packages I have an S3 method for the plot3d generic function from package rgl. I am trying to streamline my Depends entries but don't know how to have plot3d(foo) in the examples section for the plot3d method in my package, without rgl being in Depends. Note that I importFrom(rgl, plotd3d) and register my S3 method via S3Method() in the NAMESPACE. If rgl is not in

I agree, this is a good idea and would be very helpful in interactive contexts. I have a draft patch implementing this feature here: https://github.com/r-devel/r-svn/pull/122 (Append ?.patch? to the URL to get a raw patch.)

In R devel r71124, if 'x' is a factor, droplevels(x) gives factor(x, exclude = NULL) . In R 3.3.1, it gives factor(x) . If a factor 'x' has NA and levels of 'x' doesn't contain NA, factor(x) gives the expected result for droplevels(x) , but factor(x, exclude = NULL) doesn't. As I said in https://stat.ethz.ch/pipermail/r-devel/2016-May/072796.html , factor(x,

Hello, I try to set up namespaces for packages. It is fine for several of them, except one whose compilation fails (under Windows XP & R 2.0.0): ---------- Making package svViews ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata Error in parse(file, n, text, prompt) : syntax error on line 21 Execution halted make[2]: *** [nmspace] Error 1 make[1]: ***

I am cleaning up the rms package to not export functions not to be called directly by users. rms uses generic functions defined in other packages. For example there is a latex method in the Hmisc package, and rms has a latex method for objects of class "anova.rms" so there are anova.rms and latex.anova.rms functions in rms. I use:

Hi, Just reporting a small bug? not really a big deal, but I don?t think that is intended: droplevels()?also drops all object?s attributes.

Hi In NEWS, it says R CMD check now tests that the package can be loaded, and that the package and namespace (if there is one) can each be loaded in startup code (before the standard packages are loaded). For package "onion", I think I have followed all of sections 1.6.1 - 1.6.6 of R-exts, and it passes R CMD check for R-2.3.1. However, using R version 2.4.0 Under

Hello, In the current R-devel @ is S3 generic, so we can do things like - for example - use it to extract matrix rows by name: .S3method("@", "mm", function(object, name) object[name,]) m <- structure(matrix(rnorm(20), ncol=2), dimnames=list(paste0("row", 1:10), paste("col", 1:2)), class="mm") m at row1 However, seems like
