This is related to Selenium/Watir usage along side webrat in story testing. MHS_Testing and Rspec-ui provide some great help for testing through frameworks like Selenium/Watir. But there is something missing, Webrat has changed the landscape somewhat with Acceptance Tests/Story Driven development. Now I have a choice: 1. Tests and rails process run as one test process (Webrat) 2. Use

Hi all, Is there any chance that readRDS and saveRDS might one day become read.rds and write.rds? That would make them more consistent with the other reading and writing functions.

R-devel, I am interested in creating a package that requires non-GPL'd (commercial) C code to work. In essence it is a single .c file with no use of R headers (all .C callable functions). For example's sake: 1 #include <stdio.h> 2 3 void test (int *a) { 4 *a = 101; 5 } The package isn't destined for CRAN, and I realize that this isn't R-legal, but looking for

I''m trying to use Canoo WebTest (based on HtmlUnit) to test my webapp after integrating scriptaculous. While my test passed, I get a nice long exception message which barely makes any sense (see below). I found I could get rid of this message by commenting out line 114 of effects.js: 114 this.timeout = setTimeout(this.loop.bind(this), 10); Any idea of what might be causing

Hello, I'm trying to access an object, given only its name as a symbol. I cannot figure out how to proceed.

Hi, Is there any way that a package can listen for when R quits? The Qt stuff is hooking into platform-specific event loops and when those die unexpectedly (from the perspective of Qt), it aborts, causing an annoying error dialog. If we could catch when R is killed, we could cleanup, like we do with .onUnload. Thanks, Michael [[alternative HTML version deleted]]

R-helpers: What would be the absolute fastest way to make a large "empty" file (e.g. filled with all zeroes) on disk, given a byte size and a given number number of empty values. I know I can use writeBin, but the "object" in this case may be far too large to store in main memory. I'm asking because I'm going to use this file in conjunction with mmap to do parallel

To me it seems like writeBin() writes one char/byte more than expected. > con <- file("testbin", "wb") > writeBin("ttccggaa", con) > close(con) > con <- file("testbin", "rb") > readBin(con, what="character") [1] "ttccggaa" > seek(con, what=NA) [1] 9 > close(con) > con <-
