similar to: Why does format.default skip dispatch for list items?

Hello all, I am trying to port the package RProtoBuf to windows. The developers of RProtoBuf have given me some helpful pointers so far, but now I am stuck. After having made what I think are the necessary changes to the package to compile on windows, "R CMD build RProtoBuf" outputs a somewhat cryptic error ("This application has requested the Runtime to terminate it in an unusual

Hi, I notice that the CRAN binary for the macOS version of RProtoBuf is built against quite an old version of protocol buffers (from 2014, before v3 format support was added). the windows version is (blessedly) kept up-to-date, but I'd like to float the suggestion that the macOS version get an update too. with thanks jonathon

Hi, I ran into the following peculiarity involving S4 method dispatch and namespaces. I develop a package which have a namespace and which depends on 'pixmap' package, which itself does not have a namespace. Now, in my package I have a class which has a slot for objects from class "pixmap" and I want to have a "plot" method for this new class. Not to clutter the

I was wondering if anyone knows more about the state of RObjectTables. This largely undocumented functionality was introduced by Duncan around 2002 somewhere and enables you create an environment where the contents are dynamically queried by R through a hook function. It is mentioned in R Internals and ?attach. This functionality is quite powerful and allows you to e.g. offload a big database of R

Thanks Simon, I didn't know that! That's definitely a compelling reason to leave the current default untouched and to eschew any finicky attempts to find back-up editors. Still, I think there is benefit from checking quickly that 'editor' exists at run-time in file.edit() -- the current failure mode is unusual (a shell error & R warning). Offering an R error would also

I have a little problem about method dispatch and "unnessary" copying. Basically what I would like to do is: `[.myclass` <- function(x, i,j, extraopt=TRUE/FALSE, drop=TRUE) { ...do stuff depending on extraopt... value <- Nextmethod("[", x, i,j, drop=TRUE) ... do more stuff depending on extraopt... } I have two general problems: (1) NextMethod() really

The format.info() function currently takes args (x, digits = NULL, nsmall = 0), while format.default() takes many more: function (x, trim = FALSE, digits = NULL, nsmall = 0, justify = c("left", "right", "centre", "none"), width = NULL, na.encode = TRUE, scientific = NA, big.mark = "", big.interval = 3, small.mark = "",

Hi, I use lapply with a function from a package, and every 20th to 50th function execution (out of 500 to 10 000 times) fails for some unknown reason. RAM consumption ever increases (out of limit) and execution time is endless. I am not going to debug the package. (I rather feel like an end-user.) If it was Java, I'd wrap the function in a try...catch statement like about try{
