Dear List, I have examined the sp, maptools, and shapefiles packages (Windows) but cannot seem to figure out a solution for writing shapefiles for 'curvy shapes'. The scenario is that I generate a series of polygons, circles, and ellipses on a plot and would like to convert them to shapefiles. Since the circles and ellipses are do not return a coordinate list during the plotting

Dear List, Running on a PC (Windows 2000) with 256 MB RAM, Version R1.9.1 I have a relatively simple problem, which I can solve for relatively small datasets, but run into difficulties with larger ones. I believe that my approach is a hack rather than something elegant and I was hoping that somebody on this list might help me improve my code. Basically, given a vector of values (e.g.,

Dear List, I have just compiled my first R library for submission to CRAN; however, I have a tiny problem with 'R CMD check' that is holding me back. I have read extensively the PDF document on Writing R Extensions and the 'Making R Packages Under Windows' tutorial by P. Rossi. All functions are given in R code (no C/C++/Fortran) with two very simple demonstration datasets. My

Dear list, I have a dataset as follow and I would like to count the frequencies for the combination of the two variables (f1 and f2) for each id. I know it is should be straight forward, but I just don't know how to do it in R. Here is the SAS code I will use to get the output I want : proc means nway; class id f1 f2; var flag output out=temp; Dataset: id f1 f2 flag 798 1 2

Dear all, I have a data frame that looks like this: c1 c2 c3 A B C B C A A A B and so on; I?d like to produce one single vector consisting of the columns c1,c2, c3, such that vector=("A","B","A","B","C","A","C","A","B") I guess it?s easy to do but I don?t know how...Can anyone

By default, Rails logs all parameters passed to a controller method. As far as I can tell, this happens in both development and production modes. I have a form that collects some sensitive data. I don''t want that data sent to the log, at least not in production mode. Of course, I''d still like to log everything else. Is there a way to accomplish this? -- Posted via

This works fine: fit42<-nls(Vfs~SSlogis(Months,Asym.Int+Asym.Group*Groupdum,xmid,scal), data=df, start=c(Asym.Int=22,Asym.Group=5,xmid=2,scal=6), na.action=na.omit) But this, identical except using gnls, doesn't converge: fit43<-gnls(Vfs~SSlogis(Months,Asym.Int+Asym.Group*Groupdum,xmid,scal), data=df, start=c(Asym.Int=22,Asym.Group=5,xmid=2,scal=6), na.action=na.omit) Error in gnls(Vfs

I was trying to deal with foreign key issues related to order of fixture loading when I came across this: http://techpolesen.blogspot.com/2007/04/rails-fixture-tips.html This got me looking deeper into rails and I noticed that db:fixtures:load calls Fixtures.create_fixtures once for each fixture file. However, Fixtures.create_fixtures is capable of taking multiple files and also handle the

Hello guys, I am building a photo website and I have some questions before I really start programming the site. My system will be Debian + lighttpd + mysql +fastcgi + ImageMagick I plan to use file_column for image handling/verification and thumbnail creation. My question is; I need to store images in a place outside of webroot so only registered members can see them. To serve them secure

Hi, ActiveRecord does not currently support tables that have only a primary key. This seems to be a needed feature as evidenced by the tickets: http://dev.rubyonrails.org/ticket/6187 http://dev.rubyonrails.org/ticket/6319 http://dev.rubyonrails.org/ticket/7877 The update case is easily fixed by just not running the query when there are no columns to update. But the create case is problematic

All, I''ve been playing a bit with some patches to make the fixture loading and management code a little bit easier to maintain. If I were to start chopping out features, how would you feel about losing: Fixture instantiation, Old school single-file fixtures, CSV fixtures, The ability to specify a subset of fixtures (everything''s always loaded instead), The ability to

How to check an input String is a number or not in ruby? Thanks in advance, Joshua -- Posted via http://www.ruby-forum.com/.

Hi Jean-Marc I'm looking at the 1.0.5 source, and I'm not seeing an _spx_lpc(). There's an _spx_autocorr(), which is in lpc.c and is called near the start of the encoder function in nb_celp.c. The encoder seems to call the autocorr() function, then calls wld() to do something called Levinson-Durbin. Am I right in thinking that after the call to wld(), the st->lpc[] array

Hi, I spotted today following line at my FreeBSD 4.6.2-RELEASE IPFIREWALL log: Jul 1 13:34:35 fbsd /kernel: ipfw: 1400 Accept TCP xxxxxx:22 yyyyy:22 in via ed1 where xxxxxx is the attacker's IP and yyyyy is my box. But in sshd log, there are no traces left behind by this connection. Normally, there is "Did not receive identification string from xxx" etc, when somebody tries to

Hi !   I'm quite newbie with LLVM, so when replying please give sufficient information please. :-)   I want to use LLVM in windows, but apparently clang currently does not support linking of C++ classes against microsoft compiler  - due to export symbols mangling.   Subject was discussed on thread: http://comments.gmane.org/gmane.comp.compilers.clang.devel/20068 and I've tried to contact

I am trying to implement a relatively high number of encoders (24/32) on a single DSP and would like to minimize the memory requirements. Has anyone optimized the persistent EncState memory allocation for multiple channels. The default C64x fixed point implementation allocates 5280 bytes of persistent memory per encoder. I'm willing to restrict my settings to complexity 1, quality 3. It

Hi everyone! It's my first time posting to this list, and I've got a fairly technical question. I'm interested in doing phoneme extraction, and one of the first steps in the algorithm I'm planning to use is to get the LPC coefficients for an input frame. Since Speex is CELP-based, the coefficients must be generated in there somewhere. I've tried digging around in the source

Please ignore my previous mail and patch, there is a new version :). Patch changes are: - Use MAC16_16 macros instead of (sum += a*b) and unroll a loop by 2. It increase performance when using optimized macros (ex: ARMv5E). A possible side effect of loop unroll is that i don't check for odd length here. - Add NEON version of FIR filter and autocorr - Add a section in autoconf in order to
