Dear all! I wrote my R-code with an editor and loaded it with source("my_file.R"). Everything works fine as expected. When I try to start my code with: R --no-save < my_file.R I do get a synatx error half way through. The version is 1.9.0 on a Linux system.

Hi! I''m *very* new to rails, I just dove in about a month ago and I''m loving it. One thing I decided I immediately wanted to do, was shorten the number of keystrokes neccessary to URI, HTML, or Jscript encode something. The project I''ve come into already has helpers defined for this. Right now, what I''ve done is: alias h! string_esacpe_html alias u!

However if I add this to my application.rb I''ll get an error like (undefined method `newmethod'' for "123456":String) What''s wrong with that?

On a Windows platform I am trying to count the number of lines in a file. In a DOS window, the following works: C:\Users\jar>findstr /R /N "^" D:\my_dir\my_file | find /C ":" 5317 (it works with double \\ also) But in R, I need to make this string up with the file name I get from file.choose(): filename = file.choose() #get the number of lines in the file # first make a

I looked at the documentation of source() and summary(), and I could not find the reason why calling something like: > summary(resamps) from the command line, works (it prints the summary) whereas calling summary(resampls) from a file that I source with source("my_file.r") does not print anything. How can I get summary(resamps) to print when I source a file with this command?

Hi guys, Am having a problem. I have this def in my index controller that works like this: def do_something $a = variable1 $b = variable2 $c = variable3 $d = ""<script language=\"Javascript\"> \n new Insertion.Bottom(''#{$c}'', ''#{$a} - #{$b}''); \n </script>" $trigger = "1" render(:partial =>

On line 734 in src/flac/main.c, ver 1.77, change: strcat(outfilename, infilename); to strcat(outfilename, flac__file_get_basename(infilename)); I did this change because I was calling flac with an input filename with a path on the front of it, and I wanted the output file to go to a different location, such as this: flac --best --output-prefix /usr/share/flac /home/akehurst/tmp/my_file.wav

Considering the python code: for k, v in d.items(): do_something(k); do_something_else(v) I have the following for R: for (i in c(1:length(d))) { do_something(names(d[i])); do_something_else(d[[i]]) } This does not seem seems idiomatic. What is the best way of doing the same with R? Thanks. Luis

Hi! I have bootable (USB flash) disk, that _appears_ to be using syslinux. (the word syslinux is in the PBR, in the hexdump). How can I chainload it? The payload seems to be a file that I tried load with COMBOOT, COM32 etc, but nothing works (they report that the file is not in proper format, wrong magic number or simply crash). How to proceed? is there a 100% way to confirm that it is really
