[Rd] Reading clipboard with read.delim("clipboard") crash (PR#13957)
Full_Name: Liam Gretton Version: 2.9.2 OS: openSUSE 11.1 (x86_64) Submission from: (NULL) (143.210.13.77) Reading a large number of rows of delimited data via the clipboard results in a segfault or double free error. I've tested copying from various applications, but gedit will do. This problem exists in the openSUSE-supplied 2.8.1, I've just built 2.9.2 to see if it's still there, and it is. I can provide an example delimited file which demonstrates the problem; it contains about 18000 rows and 7 columns of data. read.delim("clipboard") tends to fail when only reading ~1500 rows, though I haven't been able to reproduce the point at which it fails. Reading exactly the same data from a file using read.csv("file.csv") is successful. Problem reproduced as so: Data copied to the clipboard in Gnome. > R R version 2.9.2 (2009-08-24) [snip] > data <- read.delim("clipboard") *** caught segfault *** address 0x18, cause 'memory not mapped' Traceback: 1: file(file, "r") 2: read.table(file = file, header = header, sep = sep, quote = quote, dec = dec, fill = fill, comment.char = comment.char, ...) 3: read.delim("clipboard") Possible actions: 1: abort (with core dump, if enabled) 2: normal R exit 3: exit R without saving workspace 4: exit R saving workspace On a different (but similar) openSUSE 11.1 system, the command still fails but reports: *** glibc detected *** /usr/local/R-2.9.2/lib64/R/bin/exec/R: double free of corruption (!prev): 0x0097cb70 *** Details of R build: ./configure --prefix=/usr/local/R-2.9.2 --enable-R-shlib --enable-mbcs --enable-threads=posix --with-blas --with-lapack --with-system-zlib --with-system-bzlib --with-system-pcre --with-gnu-ld No additional packages installed.

Re: [Rd] 2.10.0 Under development (unstable) (2009-09-15 r49711) just built segfaults on Debian Squeeze
I've just committed (r49747) some changes that should fix the re-entrancy bug Mark reported the other day. The problem was that R reads some files (e.g. Mark's .Rprofile) in a read-eval-print loop, and only parses them a few lines at a time. This means that within that loop, one of the evals could cause it to start parsing something else. One of the changes I put in a few days ago got confused by this. Hopefully the latest change hasn't introduced a new bug... BTW, one of the effects of this change is that a syntax error in .Rprofile should now be reported on the correct line number. In R 2.9.x the line number was relative to the current statement, so it was pretty meaningless. Duncan Murdoch __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

This unfortunately means that we cannot distinguish between 1) a path with a filename 2) a path without a filename For example in the next version of the ff-package we allow a user to specify a 'pattern' for all files of a ff dataframe which is path together with a fileprefix, the above means we cannot specify an empty prefix "" for the current working directory, because > dirname("./.")

At least on Unixoid systems, and I believe it holds for Windows systems too, "." stands for the current directory ("working directory"). Moreover, "./" means exactly the same as ".": If you list the files in "./" you will get exactly the same as if you list the files in ".". Further, "/." means the same as "/" and the same as "", so (on the same basis) "./." also means exactly the same as ".". Therefore the second "." in "./." is not a filename. What the above examples of dirname and basename usage are returning is simply a specific representation of the current working directlory. Forgive me if I have not seen the point, but what I think I have seen boils down to the interpretation I have given above. Best wishes, Ted.

[Rd] Package crashes R under Windows Vista
Dear all, Please, please I really need your help, since I am not able to solve the problem myself: It seems that until now most Windows users of my Bioconductor package "xps" use Windows XP, but recently a user tried to use it on Windows Vista where it crashed R immediately. Since I assume that some users may migrate to the upcoming Windows 7 where the problem will be the same, I would appreciate any help to be able to support Vista/Windows 7, thank you in advance. The problem ist that my package consists mainly of C++ code which I must compile with Visual C++ (Express Edition 2008), since it depends on the ROOT C++ framework. Windows users download and install first the ROOT Windows binary compiled with VC9 and then install the Windows binary of xps. Thus package xps contains a "Makefile.win" where I use one of the compiler options "/MT" or "/MD", respectively, see: http://msdn.microsoft.com/en-us/library/2kzt1wy3.aspx Since the Windows binary of ROOT is compiled with option "/MD" I should in principle use this option, however, R does not accept this option. Luckily, for Winodws XP I can compile xps with "/MT" and this works perfectly fine. The real problem is that neither option works on Windows Vista, although I can run "R CMD INSTALL" in both cases. However, when loading "library(xps)" using Rterm.exe I get the following two cases: 1, xps compiled on Vista with option "/MD": new R session: > library(xps,lib.loc="C:/home/Rabbitus/CRAN/myRlib") Error in inDL(x, as.logical(local), as.logical(now), ...) : cannot load shared library 'C:/home/CS/CRAN/myRlib/xps/libs/xps.dll': LoadLibrary failure: A DLL-Initialisationroutine failed.

[Rd] inconsistency in attaching attributes to NULL
In R-devel (svn 49628) and back to at least R 2.7.0 we get inconsistent results when attempting to attach attributes to a variable with the value NULL. If we use attributes<- it finishes but changes the value to list(). > a<-NULL > attributes(a)<-list(attr1="First attribute", attr2=2+2i) > a list() attr(,"attr1") [1] "First attribute" attr(,"attr2") [1] 2+2i If we use attr<- it refuses to attach the attribute > b<-NULL > attr(b, "attr1") <- "First attribute" Error in attr(b, "attr1") <- "First attribute" : attempt to set an attribute on NULL Is the second behavior the correct one and should attributes(x)<-list() abort if x is NULL? (attributes(NULL)<-list(attr="First") dies because NULL itself is not allowed on the left side of an assignment.)

You are requiring specific Microsoft tools to compile a package, which fails on one Microsoft OS, but not another. Isn't this a question you should address to Microsoft? For the record: We support compiling in the compiler listed in the R-admin manual, which is available from www.murdoch-sutherland.com/Rtools.

R version 2.10.0 Under development (unstable) (2009-09-08 r49628) Here are two somewhat related questions. First, when we attach a too short names vector to a vector the names vector is padded with NA's to the length of the main vector: E.g., > x<-1:3 > names(x)<-c("One","Two") > str(x) Named int [1:3] 1 2 3 - attr(*, "names")= chr [1:3] "One" "Two" NA I expected this length mismatch to cause an error, but I am biassed by my long usage of S and S+. Is the extension by padding with NA what is wanted? Second, if we extend a named vector with length<- the main vector is padded with NA's but the names are padded with empty strings.
