similar to: bug: sticky symbol refs? (PR#9555)

Hello. I was writing some code that computes on the language and came across this. I can work around it, but thought you might like to know about it. > f <- function(x) { NULL } > a <- as.list(f)[[1]] > a # ie print(a) Error: argument "a" is missing, with no default Note it says *argument* "a", which is strange. In fact, and unsurprisingly, the bug lies with

Dear all, Another question related to my ggplot package: I have made some substantial changes to the backend of my package so that plot objects can now describe themselves much better. A consequence of this is that a number of convenience functions that previously I wrote by hand, can now be written automatically. What is the best practice for creating these functions for bundling in a

Hello! Maybe "frame" is not the right term in this context. I explain my problem by example code: fun2 <- function(objName, add) { ## the object "objName" should be increased by "add", ## but the evaluation should be done in the calling function (here: fun1) ## ...... what's the right code?? } fun1 <- function() { x <- 1 fun2("x",

ls() gives me the vector of objects in the workspace class(objName) gives me the class of objName class(ls()) just returns character as many times as there are objects. How do I get a vector of all objects in the workspace? [[alternative HTML version deleted]]

Dear list, I came across a behavior that IMHO is somewhat undesired when calling '$field()': If the field name whose value you're trying to get is *not* a valid field of the Reference Class, then R doesn't stop there with an error, but scans through all enclosing environments/frames. The result is something similar to calling '|get(<objname>, inherits=TRUE)|'

Dear R users, I am currently writing a R package and to do so I am following the guidelines in manual 'Writing R extensions'. In Section 3.1, it is suggested to tidy up the code using a file containing the following: options(keep.source = FALSE) source("myfuns..R") dump(ls(all = TRUE), file = new.myfuns.R") I have done this for my own packages and although it runs, I get

Hi list, Is there a way to load one specific object from a .RData file which contains multiple data objects?? Thanks, ...Tao

Hello there, tl;dr: Is it a known behaviour that using llvm-3.4 and llvm-3.6 at the same time in the same process (while llvm-3.6 is used from a linked shared library and llvm-3.4 is dlopen'ed - with a strange detail: Especially if -rdynamic is used when linking the program). If so, is there a workaround? If not, can it be fixed in llvm-3.6? Long story: I am writing a program that creates

Hi R experts, Could you please help me to fit a linear, cubic and quadratic curve in a figure? I was trying to show all these three fitting curves with different colour in one figure. I spent substantial time to figure it out, but I could not. I have given here a example and what I did for linear, but no idea for cubic and quadratic fitting curve > dput(test) structure(list(sp = c(4L, 5L,

Hi R-users: When I type the following code in R, using the svIO package I got a problem only with the "latex" type option.(With "raw", "ascii" and "html" options, it works fine). x<-1:50 copy('x', type='latex', objname='x') Erro en file.info(fn <- c(...)) : argumento del nombre de archivo inv?lido Thank you for your help.

Dear List, I have a series of nested loops with the structure shown below, and I am struggling to figure out how to divert output to folders created with dir.create() within the loops. What I need is for the output to end up as topNameK/subNameL/objNameM.pdf; what I get instead is a series of directories topNameK/, directories subNameL/, and files objNameM.pdf, all in the working directory. Any

Ok, thanks for clearing it up. But: > It's not a bug things work in ways that confuse users when they pry > into things they were not expected to pry into.... Do you have a good= > reason to call this a bug? Well if it's intended to work that way then it's not a bug. As I said, I was computing on the language, in particular writing code = that processes the parse tree of a

Despite the spirited arguments of various R-core folks who feel that mle() doesn't need a "data" argument, and that users would be better off learning to deal with function closures, I am *still* trying to make such things work in a reasonably smooth fashion ... Is there a standard idiom for "merging" environments? i.e., suppose a function has an environment that I want

I would like to write a function that computes Tukey's 1 df for nonadditivity. Here is a simplified version of the function I'd like to write: (m is an object created by lm): tukey.test <- function(m) { m1 <- update(m, ~.+I(predict(m)^2)) summary(m1)$coef } The t-test for the added variable is Tukey's test. This won't work: data(BOD) m1 <- lm(demand~Time,BOD)

Dear developers, is it possible to create environments in C code of packages? Simply using SEXP env; PROTECT (env = allocSExp(ENVSXP)); and assigning the enclosing environment with SET_ENCLOS seems to be insufficient.

I'm getting a segfault when I call `SDL_Init( SDL_INIT_VIDEO )` within the MCJIT.  If I compile the same program to an EXE I don't have a problem. Are there any general restrictions, or known issues, with loading a library like SDL2 via the MCJIT?  (LLVM-3.8 still) The stack trace, from GDB, is below. I noticed the error actually happens deep inside a transitively loaded GL drive module,

Hi, I am running the non-parametric rasch model tests using eRm. I have a reasonably large dataset for this type of exercise (110 items, 248 persons). I run: > allb2=as.matrix(allb) > rsample <- rsampler(allb2, ctr) > t102<-NPtest(rsample, method="T10") #global test, subgroup inv and receive error message as follows. "Error in m[idx1, idx2] <- 1 : subscript out

I am looking for a way to save a plot (graphics contents) to a file after the plot has been calculated but before it has been rendered. More specifically, assume that I made a plot that took a very long time to produce, I would like to save this plot to a generic file that I can later, on a different machine, render to either PDF, PNG, SVG using the usual R graphics devices, without recalculating
