Just in case anybody want''s to give Amazon''s new (currently in closed beta) SimpleDB web service a test drive with Rails... I just finished work on a Proxy Server bridging the APIs. It''s available as a Rails Plugin: http://inside.glnetworks.de/2008/01/20/bridging-rails-to-amazon-simpledb-using-activeresource/ (also available via

I did some searching in the mail archives and didn't see any discussion of integration with AWS, so I wanted to through out my thoughts/plans and see if it has been done before. I am setting up my own personal website on EC2 along with an email server, and I really don't like the idea of using the disk drive as permanent mail storage. EBS is too small instance storage is ephermeral.

Hi folks, I was wondering if anyone could confirm/deny whether there exists any kind of package to facilitate zoomable graphs with multiple plots (eg, plot(..) and then points(..)). I've tried zoom from IDPmisc, and iplot from the iplot and iplot extreme packages, but as far I can tell, neither can handle the task. Does anyone know anything else that might work? Or generally know

I've been involved with getting better data for running Asterisk on the Amazon EC2 cloud computing system. Here are some calculations I've made on costs based on current published prices on Amazon's system. Feel free to tell me that I'm wrong with these calculations - but be specific if you find any problems, as I suspect others may glom onto these figures as gospel and

Dear all, I was wondering if someone could point me in the right direction to solve a problem I've encountered. I have a set of S-plus scripts which call an external program to analyse the data (the external program is called Genehunter and is used for genetic analysis). There are a six scripts in total, five of which are called from the main script. I made a few changes like changing

Can R handle graphic text ? I mean something like a pop-up message window or a text widget ? Thank you so much. -- Maura E.M

Hi, I'm scratching my head as to why I can't use the subset() command to remove one line of data from a data frame. There is just one row (out of 45840) that I'd like to remove and it can be identified using.... > dim(raw.all.clean) [1] 45840 10 > subset(raw.all.clean, Height.1 == 0 & Height.2 == 0) Sample.Name Well SNP Allele.1 Allele.2 Size.1 Size.2

Dear all, Thanks to those of you who have replied, the majority of the comments pointed out that the error caused by scan may originate from another function, and closer inspection of the output from traceback() reveals that it is in fact the read.table function where the error is originating from the full output of which I have included below. The error msg I recieve is Error in

I am posting this to both R and BioC communities because I believe there is a lot of confusion on this topic in both communities (having searched the mail archives of both) and I am hoping that someone will have information that can be shared with both communities. I have seen countless questions on the BioC list regarding limma (Bioconductor) and its calculation of FDR. Some of them involved

Hello, I am trying to convert a simple data.frame (it will always be a few equally long variables) into the XML format (which I don't understand too well but need as input for another program) and reverse the operation (from XML back into data.frame). I found some code which does the first and it works good enough for me (see below). Is there an easy way to reverse the operation? My XML files

So far I''m disappointed with what I see as red flags. I follow along what seems like foolproof instructions. I install everything, rails new /some/new/app cd to the directory and rails server and my worst fears cryptic useless stack trace...so I copy the top line, search for stuff on this sqllite3 adaptor to fix it, I type the gem install command it mentions (gem install

I've just hastily migrated from Dovecot 1.2.9 to 2.2.9 due to a disk crash. When I say hastily, I literally copied the user's mail data files to the new server and then started the Dovecot service. The trouble is, I now have a user who can see all the subfolders of her inbox in Outlook, but not on her iPad. Do I need to re-index her mail folders? The data is there (as seen by Outlook

Hi, I noticed recently when installing the GDD package for R under GNU/Linux that it required the gd library (http://libgd.org/) for generating graphics. The resolution of this was to simply install the library on my system, and then GDD successfully installed without any complaints. However, the variant of GNU/Linux that I use is Gentoo, so I filed a bug requesting that a USE flag be set for

The CRAN Taskviews (http://cran.r-project.org/web/packages/Views/) is currently unavailable and returns 404 Object not found! This is possibly due to them now being linked from the side frame and the URL now being http://cran.r-project.org/web/views/ Unfortunately the webmaster link on the 404 page does not have any email address associated with it, hence the mail to the list.

Amazon (or perhaps Amazon's configuration of Xen) forces a machine to come up at run level 4, regardless of what's in /etc/inittab. I've looked through /etc/rc.sysinit and /etc/rc.d/rc, to determine which (if any script) looks at /proc/cmdline and forces a particular run level, but to no avail. It seems that /sbin/init does the forcing. Can anyone confirm that /sbin/init reads
