Hi, I am trying to compile the R-dev version on a unix Suse machine and got errors. Would someone be able to help me determine what to do to fix these errors: make[1]: Entering directory `/lustre/people/schaffer/R-devel/m4' make[1]: Nothing to be done for `R'. make[1]: Leaving directory `/lustre/people/schaffer/R-devel/m4' make[1]: Entering directory `/lustre/people/schaffer/R-devel/tools' make[1]: Nothing to be done for `R'. make[1]: Leaving directory `/lustre/people/schaffer/R-devel/t...

Hi, I need to convert numbers to characters in order to index an array when I encountered the number 100000 which turned into "1e+05". Does anyone know how to get around this problem?

I found an interesting page today that I was trying to script against. The server returns a 404 with content and the page just works normally in firefox despite the 404. Mechanize raises an exception on it though. I''m working on a test case now.

...timation for a problem that is quite similar in form to the alpha-pinene example in Bates and Watts (1988), p. 147, where the model is a set of ODEs. I am specifically interested in obtaining the parameter covariance matrix, as well. Which package(s) in R would I use to do such a thing?

Hi, Can someone suggest an efficient way to substitute a vector/matrix which contains 1's and 0's to P's and A's (resp.)? Thanks, Lana

Is there a decent way to add a field to a form before posting it? I haven''t tried using HPricot manipulations just yet, since I can''t ever find really solid docs on hpricot.... Form#[]= doesn''t work because it first searches only pre-existing fields. I''m investigating how to write a patch now. But I thought maybe someone here might have an idea.

Hi, This is my first post, I wanted to ask a quick question about "Bad Form" -- rather, am I doing something with Mechanise I shouldn''t be doing? Here''s the long and short of it - I am using Mechanize with Cucumber and RSpec to test a *ahem* Perl XML web service.. talk about technology soup, but I have it working quite well. I have an example project on GitHub that

How can plots (histograms) be implemented with the command line interface to R? Lana Schaffer

So I found myself wanting to call Mechanize#get with a hash for arguments like this: WWW::Mechanize.new(''http://api.flickr.com/services/rest/'', {:method => ''flickr.auth.getFrob''... }) Granted, it looks like this isn''t supported but it led me to what looks like a bug. Namely that get calls fetch_page(abs_uri, request, cur_page, &block)

Friends, Is there a Partial Least Squares package implemented in R? Thanks, Lana [[alternative HTML version deleted]]

I''ve been reading, hearing, and looking at blogs that state Ruby on Rails is rather slow. Coming from a VB 6 world (thank you Microsoft for killing VB because VB.NET is NOT VB) I was always told that VB was a toy or too slow. Now, I''ll easily tell you that yes VB was not a great language. It had it''s share of warts, like a lot of other languages I might add, but

I haven''t spent the time to get a proper test case for this yet, but there appears to be a bug in the basic_auth code for mechanize 0.6.9. I''ve attached a CSV (from Charles) that illustrates the problem. Basically when running with basic_auth, there''s a failed request that''s followed up by a successful request. That last POST is a agent.submit(form)

I am not able to find information about doing line plots with error bars in the R- help information. Would someone like to tell me if this can be done in R and either get me started or lead me to information about how to do the error bars? Thanks, Lana

I noticed an interesting problem today when scripting against a web app. The application contained a link in it that used %20 instead of spaces. After running mechanize through the Charles debugging proxy I found that mechanize was converting %20 to %2520 (double escaping the %20). This appears to happen under both 0.5.4 and 0.6.0. Here''s a simple set of files that demonstrate

I''ve been noticing about a 2 second pause between PUT requests when running either webrick or mongrel. GET, LIST and DELETE all work great. I tested this by using curl to make a lot of continuous requests. Even if I remove everything from the controller method and just replace it with render(:nothing => true) I still get the lag. So I don''t think it''s

Hi, when I call the function "list.files()" it also lists directories, although the parameter include.dirs is set to FALSE by default. The function also lists directories when the parameter include.dirs is explicitly set to FALSE "list.files(include.dirs=FALSE)". I have tested this also on a mac os -> same results. kind regards, simon > sessionInfo() R version 2.15.1

I''ve this small test app where I''m saving a user profile picture in a subdirectory under "public" folder. Now when a user uploads a picture - a unique directory is created under his id and then his/her image is stored there. Now while retrieving the image I only get the path name and nothing else. How can I get the image shown in the browser...HELP PLEASE!!! --

Hey, Aaron. Looks like that get with hash params patch you checked in had some side effects. Specifically, you''re testing if a referer is a Page (mechanize.rb:171), but the referer could also be a WWW::Mechanize::File. Like if the last page loaded was xml. Here''s a patch that addresses the issue. Thanks again, Mat -------------- next part -------------- A non-text
