Hi, I am not sure if this is the right list to ask this question (though I did not find a more appropriate one). I've started using R a month ago, and small scripts work fine. However, when I start writing more complex code, it gets messy. 1. Is there any way to debug "normally", with breakpoints? 2. I am using the Eclipse plugin (StatET), and tried JGR(). Is there an IDE that

Hello, I've been using jpeg(), bmp() and pdf() to capture plots. I've used the parameter "at" in a plot, to define the tickmarks. It works fine on screen, but when I try to print it to a file, it gives a warning: "at" is not a graphical parameter and prints an empty figure. Can you help? Thanks, Eran.

Hello, I have a time-series that has some missing samples. I was thinking on completing them using either zero-order hold or linear interpolation. I am looking for an efiicient way (other than a loop...) of identifiying the missing time slots and filling them. Can you think of any methods that might help here? (obviously which(diff(time)>min(diff(time))) will give the locations, but what

Hello, I've switched to R studio from the StatET Eclipse plug-in. I have a question regarding navigating between plots. When I use x11() or windows() new devices are created and I know how to switch back and forth between them. However, when I plot on the device that stands for R-Studio's built-in plot browser, is there a way to switch back between plots? Each new "plot"

Hello, I wonder how I might create a package that only reveals some of the function in the package to the user. I've tried creating an R package using the following: f <- function(x,y) x+y g <- function(x,y) x-y h <- function(x,y) f(x,y)*g(x,y) package.skeleton(list=c("f","g","h"), name="mypkg") and would like only h() to be available when I

Hello, I have a function with a long list of parameters (of different types, numeric and string) myFunc <-function(p1, p2, p3, p4, p5...etc) { do.something(p1,p2,....) } I want to loop over this to provide a different set of parameters to the list every time. for (ii in 1:N) { myFunc(p1(ii), p2(ii),....etc) } I would like to simplify the notation and use some kind of structure, maybe

Hi all, Is there a way to create a "dictionary" in R, such that it has <key,value> pairs? Something to the effect of: x=dictionary(c("Hi","Why","water") , c(1,5,4)) x["Why"]=5 In truth I'm looking two categorial variables function. So that if x=dictionary(c("a","b"),c(5,2)) x val 1 a 5 2 b 2 I want to compute

Thanks, Eran. I’m not sure how soon I’ll have a solution for you, but it’s on my to-do list now.

Eran, Is there any chance you could boil this down to a small reproducer? I’ve got a mid-to-long-term goal of getting rid of the ugliness in LLDB that Jim mentioned, and fixing your problem would be a good first step.

For anyone encountering this problem in the future, the cause of this problem was debugging symbols (-g) given to clang when generating IR.

Thank you for the help. The relocation type value is anded with 0xffffffffL. (RuntimeDyldMachO.cpp:214) Maybe this mask should be different? Anyway, it seems like this relocation isn't implemented.

Existing clients (LLDB) deal with externals by resolving them to constant function pointers that are referenced in the IR. That’s obviously ugly as hell, but it gets things done. The old JIT was able to simplify things because it assumed the JITed code was running in the same process as the JIT compiler. The MCJIT doesn’t assume that, so it has to handle more possibilities. For example, that the

The MachO handling isn’t always straightforward in that it has a lot of bit fields to handle while it’s also trying to accommodate the format abstractions baked into the interfaces. The actual relocation type gets extracted in the RuntimeDyldMachO::resolveRelocation function (RuntimeDyldMachO.cpp:32) before it is passed on to the architecture-specific handlers. So the mask you mentioned is

Dear R-users, We are monitoring the activity of animals during a few days period. The data from each animal (crossing of infra-red beam) are collected as a time series (in 30 min bins). An example is attached below. y <- c(0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,3,28,27,46,76,77,60,19,35,55,59,48 ,87,20,38,82,62,60,85,105,69,109,102,100,101,116,126,119,63,27,25,15,8,0

Hi, I'm having problems when trying to JIT IR generated from C++ with clang. My code resides in a dynamically loaded shared object, and crashes when I call getPointerToFunction, claiming that it encountered a pseudo instruction. Interestingly, a very similar code that run as a separate executable JITing the same IR works fine. Note that I have not have modified LLVM. Any suggestions what

I a rather dependent upon the Enhanched Zoom Desktop tool. It allows me to zoom into a part of the screen and see it clearly, with the zoomed part of the screen following the mouse. However, there are times when I need the screen to remain where it is (not to pan with the mouse), and the only way that I've found to do that is with the "Toggle zoom area lock" option. When this option

Hi, I have a problem with JIT code generation on mac. The LLVM-IR I have is fine, but the machine code generated crashes. I see two instructions "add %al,(%eax)" (which are four 0 bytes, numerically) prior to function calls. As eax holds the pointer to the called function, this crashes with SIGBUS. These instructions don't make sense in the context of the code, which is why
