Dear R-users -- I'm using R 1.3.0 on a PC running SuSE Linux 7.1. I'm confused by the following behavior from the gsub() function. Am I doing something wrong? ## A string of characters > string<-c("q","w","e","(",")","q","w","e") ## Use gsub to replace `q' with `A' >

Dear members, I am trying to use boot () to compute the distributions of a statistic of a data set. The statistic is defined in the following code: eds<-function(x) { r<-cor(x) paren<-1-abs(r)/2 denom<-sum(sum(paren)+0.5) desvio<-sd(x) media<-mean(x) a<-desvio/media

Hello, Just upgraded to 2.5.0, and found that R now includes an rparen (right parentheses) or rbracket whenever I enter in an lparen. While I can see the use of this function, it doesn't mesh well with my personal style of using R (e.g., using the up arrow, adding an rparen, jumping to the beginning of the line, and then wrapping a summary, for instance). Some 10 minutes of google

...actual.should_not equal(expected) #equal, in this example, is a method that returns an expectation matcher, which Ruby passes to #should, which then interacts with the matcher to evaluate whether or not the expectation is met and report accordingly. All args to expectation matchers will require parens, and blocks must be expressed using curly braces. This has to do with ambiguity of arguments and operator precedence. Don''t worry, if you do the wrong thing you''ll get a warning. More on this below. == Why this change? The current syntax is supported by some very clever use of m...

Hi guys, I''m very new to the RoR. So please be kind to me.. I''m having problems with ferret installation in rubygems.

I have a little helper that lets me add legacy fields to models where they have common prefixes, suffixes, or something else weird. Here is the method signature: def legacy_fields(options = {}, *attributes) ..... end options is a hash containing things like :prefix => "post_" - and attributes is a list of attribute names. This gets mixed into the class with extend, so I call

We use an environment variable to control whether or not to enable a debug build of wxRuby. This was called simply DEBUG but I have renamed it to WXRUBY_DEBUG. I also added a second environment variable, WXRUBY_VERBOSE, which turns on extensive console output that can help debug memory problems. It prints a message any time an object is created, destroyed, etc. This used to only be an option in

print "" is no more available in Python 3, and print(...) is available since Python 2.7; as one of the tests was using print(), use this form everywhere so the tests can run fine with Python 3. --- python/t/820-rhbz912499.py | 18 +++++++++--------- python/t/910-libvirt.py | 4 ++-- 2 files changed, 11 insertions(+), 11 deletions(-) diff --git a/python/t/820-rhbz912499.py

I had a look at this, and worked out most of a function to do it. There are three things I haven't been able to figure out, however. 1) Getting the last N lines of the command history into a vector of strings. I thought something like: last.commands<-history(N) would work, but no go. There doesn't seem to be a file that I can tail, either. 2) Finding continuation lines by

I just joined this mail-list, so I apologize if this has been discussed before, but: Has anyone suggested adding a "todo list notation" to Markdown? Specifically, I'd like to see an open paren, brace or bracket, at the start of a line, followed by a space, a "/", or a "X", followed by a matching closing paren, brace, or bracket, followed by a space and more text

1. I have seen examples similar to the following: image = MiniMagick::Image.from_file("input.jpg") image.resize "100x100" image.write("output.jpg") I''m assuming that image.resize is a method. Is there any significance to the fact that the argument for that method is not enclosed in parenthesis while the other are? Examples seem to be consistent --

I ran into this and found the result very surprising: identical( quote({ a }), quote({ a }) ) # FALSE It seems related to curly braces. For example, parens work fine: identical( quote(( a )), quote(( a )) ) # TRUE Is this expected behavior? I can't seem to find anything in the help for identical that relates to this. -Winston
