The packages "readxl" and "haven" (and possibly others) no longer access files on shared network drives. The problem appears to be in the normalizePath() function. The file can be read from a local drive or by functions that don't call normalizePath(). The error thrown is Error: path[1]="\\Hzndhhsvf2/data/OCPH/EPI/BHSDM/Group/17.xls": The system cannot find the

Bill, I have clarified this on SO, and I will copy that clarification in here: "Sure, we tested them on other 8-digit numbers as well & we could not replicate. However, these are honest-to-goodness numbers generated by a non-adversarial system that has no conception of these numbers being used for anything other than a unique key for an entity -- these are not a specially constructed

Bill, Appreciate the point that both you and Serguei are making, but the sequence in question is not a selected or filtered set. These are values as observed in a sequence from a mechanism described below. The probabilities required to generate this exact sequence in the wild seem staggering to me.

This is cross-posted from SO (https://stackoverflow.com/q/47079702/1414455), but I now feel that this needs someone from R-Devel to help understand why this is happening. We are facing a weird situation in our code when using R's [`runif`][1] and setting seed with `set.seed` with the `kind = NULL` option (which resolves, unless I am mistaken, to `kind = "default"`; the default being

I found this as well. At our institution, our home directories are on network shares that are mapped to local drives. The default, it appears, is to set the location for libraries (etc) to the network share name (//computer//share/director/a/b/user) rather than the local drive mapping (H:/). Given the issue with dir.create(), this means it's impossible to install packages (since it tries to

The random numbers in a stream initialized with one seed should have about the desired distribution. You don't win by changing the seed all the time. Your seeds caused the first numbers of a bunch of streams to be about the same, but the second and subsequent entries in each stream do look uniformly distributed. You didn't say what your 'upstream process' was, but it is easy to

Another other generator is subject to the same problem with the same probabilitiy. > Filter(function(s){set.seed(s, kind="Knuth-TAOCP-2002");runif(1,17,26)>25.99}, 1:10000) [1] 280 415 826 1372 2224 2544 3270 3594 3809 4116 4236 5018 5692 7043 7212 7364 7747 9256 9491 9568 9886 Bill Dunlap TIBCO Software wdunlap tibco.com On Fri, Nov 3, 2017 at 10:31 AM, Tirthankar

Tirthankar, "random number generators" do not produce random numbers. Any given generator produces a fixed sequence of numbers that appear to meet various tests of randomness. By picking a seed you enter that sequence in a particular place and subsequent numbers in the sequence appear to be unrelated. There are no guarantees that if YOU pick a SET of seeds they won't produce

I wonder if this could be related to the issue that I submitted to bugzilla about two months ago? ( https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=17159) That is to say, could it be that it's treating the first path after the single backslash as an actual directory, rather than as the name of the share? -- Evan Cortens, PhD Institutional Analyst - Office of Institutional Analysis

The patch below adds support for custom HTTP headers in download.file() and url(). My main motivation for this is performing basic http authentication. Some web sites do not support embedding the credentials into the URI itself, they only work if the username and password are sent in the HTTP headers. In fact specifying the username and password in the URI has been

Dear all, as the bug # 7991 is flagged not-reproducible, let me give you some pieces of code, as I have the same or similar problem.

Hello, I am using R version 1.8.1 on a linux machine (Suse 8.2.). I have problems to use readLines() with urls. This seems to be a problem with our proxy-server.

Hello everyone, I get (reproducible) segfaults when I try to update my packages, and was wondering whether anyone knows why this might be happening. I am trying to update my packages: 1. I start R via sudo in a terminal 2. I type update.packages() - a Tcl/Tk list pops up, I select a mirror 3. R segfaults. Maybe I need to update to a newer version of R or something? Slightly OT, but does anyone
