similar to: Is there an implementation for "URL Encoding" (/format) in R?

Hello, Based on yesterday's R-help thread (help: program efficiency), and following Bill's suggestions, it appeared that sequence: > sequence function (nvec) unlist(lapply(nvec, seq_len)) <environment: namespace:base> could benefit from being written in C to avoid unnecessary memory allocations. I made this version using inline: require( inline ) sequence_c <- local( {

Hi all! I read R Extensions manual. But still I am not sure how to call R functions from C. Would any of you give me a sample C code to show how to call R functions - for instance, time series functions - from C in the embedded way of C code? [[alternative HTML version deleted]]

Muchas gracias Jesús, Por lo que veo hay que hacer una columna diferente para los símbolos, tal como sugiere Carlos. No hay forma de ubicarlos en el mismo string, acompañando al número?

Firefox used to render <ol type="a"> <li>.................</li> as a. ............... Now it does not. The HTML 4.1 spec at http://www.w3.org/TR/html401/struct/lists.html#type-values says use CSS instead. These <ol type="a"> <ol type="A"> <ol type="i"> used to work in the Centos 5 supplied Firefox. Now OL

When I previously designed my static sites in dreamweaver, I used an Open Browser Window behavior which opened a URL in a new window of fixed size by inserting the following: <a href="javascript:;" onclick="MM_openBrWindow(''example.html'', ... ''width=300,height=300'')</a> Is there a simple way to do the same thing in ruby?

Hi all, I''m a relative noob to rails so I apologize in advance for asking such a basic question. I am trying to do multiple AJAX calls using the link_to_remote helper or the JavaScript generator update_page. I have googled and read the docs for both, but can''t seem to figure out exactly what i need to do. Say I have the following html: <div

Ok well you state yourself that you are getting an XML error when you try to start icecast... Have you attempted to validate your XML? >>*Fatal: error parsing config file [icecast/usr/local/etc/icecast.xml]* * * *What command are you running to start it? i would assume it's "icecast -c /icecast/usr/local/etc/icecast.xml" which would mean to me that somehow you have a top level

Hi everyone, David R. here; I''m new to this mailing list but I''ve been incredibly wrapped up in Ruby on Rails for the last two or three months. I''ve built a fully functional web application and we''re about to roll it out to our customers. However, my supervisor would like to add just one more feature to it: listing the number of online users for a particular

I''m at the bloody forehead stage, so I figure it''s time to ask. After installing the robot coop''s memcache-client which everyone apparently recommends, it refuses to work because the rails cache.rb is invoking the read() method on the cache, which it _does not have_. Their library has get() and put() but no read() and write() as rails expects. What gives? Is
