Is this the last bug of the year? Well, it's the last one from me, anyway... The "parse" function seems to give erratic behaviour when used in conjunction with "pushBack" on an open connection (R1.6.1, Windows 2000). Try this: > { cat( c( '1', 'a+b', '2'), file='r123.r', sep='\n'); tcon_ file( 'r123.r'); open( tcon);

Dear all, I discovered that read.table (RW1.8.0) leaves out data when reading multiple-line records. Replication code at the end Best regards Jens Oehlschlägel > filename <- "c:/tmp/c2.csv" > > data <- data.frame(a=c("c", "e\nnewline"), b=c("d", '"quoted simpleline"')) > > #look at the data >

Hello, Are there any chances of next stable release appearing soonish? I'm getting pushback from Homebrew maintainers about the massive amount of patching required to build the current stable on Mac, since all the patches have been merged in after last stable. (I'm also getting pushback about the 4GB download of virtual appliance, but as I understand that one is non-optional. Don't

Tomas, Thank you for the explanation. I see in the documentation: "These functions are intended to be used with binary-mode connections." So I see how using it on a text connection is undefined, and not a bug. An error or warning when attempting to use a it on a text connection would be helpful considering how the behavior has changed in R-3.5. On Tue, May 29, 2018 at 3:09 AM, Tomas

We are getting some pushback from our SA group regarding root having ssh user equivalence on the cluster where we run OCFS2. Is it required to have the ssh user equivalence setup for the root user when running OCFS2 ?

I noticed an issue where readChar does not return the correct value after a call to readline. It appears that readChar is not aware of the buffering, so it reads from the end of the buffer, rather than the current position in the file. This is a significant change of behavior from R-3.4.4. Below is a test case that I used to home in on the problem. --- p<-"test2.txt"

In a C++ extension to R (v 1.8.1), I've been experimenting with a generic "push back" function to tack one value at a time onto the end of an R vector created within the extension. After calling this function a certain number of times Rgui.exe (I'm writing in Windows using Visual Studio .NET 2003) will fail with an Access Violation, which doesn't happen when I pre-allocate

The 'read.table' function appears to be up to 10X slower in R 1.4.0 than R 1.3.1 for some of the data sets I read in. I was comparing the source code for the 2 versions and see that it was rewritten in R 1.4.0. I think I found out what part of the problem might be. I was comparing R1.3.1 and R1.4.0 code and it appears that a statement is missing in some of the code for R 1.4. This is

In the past, I've seen some pushback on the list against adding more register classes. You can see it in the code as well, TargetLowering::getRegClassForInlineAsmConstraint() returns a vector of registers instead of a real register class. What is the reason we don't like adding register classes? Is it still a valid reason? The new register allocators, fast and greedy, don't care at

Hi, Building LLVM with a newer GCC version seems to generate several compiler warnings, some of which look like false positives. For example, the '-Winit-list-lifetime' warning added in GCC9 triggers for one of the constructors for ArrayRef, the one taking an initializer_list. How are false positive warnings dealt with in LLVM in general? It's of course possible to just ignore them

This is a followup to the discussion that started in D28791. To provide the context, we need a way to provide __dso_handle in Fuchsia. __dso_handle symbol is mandated by C++ ABI with a value which is an address in one of the object's segments, and as such this symbol has to be included statically and cannot be a part of a shared library. Different systems provide it differently: 1. On

I have a recursive function. The recursion forms a tree with many (millions) terminal nodes. The function must output a value (say, a number or a vector) from each terminal node. At the end, when all recursion is done, we want to collect all the output values. How can that be done cleanly and efficiently? A prototype example is a recursive function that generates all permutations of a vector (or
