similar to: .First and loading a package in a workspace

Dear R-Users, I think I have encountered a potential bug (or at least unwanted behavior), but I'm not sure so I wanted to post here first. Lately I've been encountering an error when running a package I put together. I have my package set up to check for updates when it loads but this error occurs and stops the package from loading: Error : .onLoad failed in loadNamespace() for

Hi, I saved an image and planed to open it whenever I want to load it. However, when I open it, It doesn't work. The code is following, and saved it as an image. .First<-function(){ require(tcltk) require(TeachingDemos) library(gWidgetstcltk) options(guiToolkit = "tcltk") win <- gwindow("Don't worry", visible = FALSE) } Error message is following, Error :

We need more compiler people in this industry. :) This is actually a very good time to be getting

Hi, I have seen the answer to this sometime before but I just can't find it again - pointers appreciated. I have a package that contains some data.frames saved as .Rda files in the data/ directory. When the package is loaded I would like to have them be available in the workspace (without the user having to explicitly load them using data(...)). If my package does not use a NAMESPACE, I can

I'm creating a package for my own use that uses some S4 classes but no methods. I have a file called NAMESPACE it contains the line: exportClasses("foo") and at the top of the R file I have setClass("foo", representation(x="numeric") and the line: .onLoad<-function(libname,pkgname) When I run R CMD check I get Syntax error in the only R file. If I

Dear all, One day when I tried to load an existing workspace (when opening R or by load()), R crashed without any error notification. The day before I had worked and saved my workspace without any trouble. At first I though it was a memory problem (workspace reaching 180Mo) or related to a particular script or command, so I start a new workspace. Everything was ok, that script and others

The lattice package has a namespace, so it has a .onLoad function. I also keep around a .First.lib, for use during development, when I temporarily delete the NAMESPACE file. When using a namespace, I used to comment out the .First.lib function. However, that seems unnecessary since it's not executed anyway. Is this intended (and dependable) behaviour? (If so, this should probably be

Hello R, To analyze multi-level data, I started learning and using lmer. So far so wonderful. I then found some useful functions in package languageR. But then the following problem ocurred: Whenever I load and use the languageR package, then save the workspace - or quit R with saving the workspace - I am unable to reload that workspace in a later session. That is, R doesn't start at all

Documentation on how to put classes and methods in packages with namespace? How should I define my classes and methods in "dynamicGraph"??? (That is - Can some one point me to the documentation on how to put classes and methods in packages with a namespace? ) Currently it is done by the code below. This gives problems, when a workspace with a "dynmaicGraph" is

I just found out that an .onLoad() function such as this stylized one (where I just renamed some identifiers) .onLoad <- function(lib, pkg) { require(zoo, quiet=TRUE, warn.conflicts=FALSE) library.dynam("foolib", pkg, lib ) if (.Platform$OS.type != "windows") { initSomeServices() } if (.Platform$OS.type != "windows") {

While working on an application, I have run into an interesting problem for which I have no solution at this moment, hence writing to this forum. Basically, I am working on an email application that requires me to fetch data from the backend using AJAX and then I use dom to append the results dynamically to the mail display table. So far so good. So, I call a function getTableData() at the end

Dear R, The glmulti package no longer loads through the library() command, apparently because of a problem with rJava. I have today reinstalled R from scratch (updated to v2.14.0) and reinstalled all packages from scratch and updated them all too. The problem is the same as I found on v2.13.2. See session below for the error. I tried install.packages(rJava) as advised by the error report but it

Hello everyone I am Rakshit Singla, a third year undergrad at IIT Hyderabad, India. I finished a basic compilers course last semester and am currently doing a compiler optimizations course.

I would like to work with LLVM and contribute to the

We ran into a bug in our package that seems to boil down to isNamespaceLoaded() returning TRUE for namespaces that R is currently loading. We had something like this in an .onLoad function: if (isNamespaceLoaded("upstream")) { upstream::upstream_function() } Which seems OK, unless upstream (recursively) imports the package having this code. Should that happen, the loading of
