[I originally posted this on the R-help mailing list, and it was suggested that R-devel would be a better place to dicuss it.] Running ?table? on a factor with levels containing non-ASCII characters seems to result in extremely bad performance on Windows. Here?s a simple example with benchmark results (I?ve reduced the number of replications to make the function finish within reasonable time):

Full_Name: Steven McKinney Version: 2.9.0 OS: Mac OS X 10.5.6 Submission from: (NULL) (142.103.207.10) A corrupt data frame can be constructed as follows: foo <- matrix(1:12, nrow = 3) bar <- data.frame(foo) bar$NewCol <- foo[foo[, 1] == 4, 4] bar lapply(bar, length) > foo <- matrix(1:12, nrow = 3) > bar <- data.frame(foo) > bar$NewCol <- foo[foo[, 1] == 4, 4]

Hi all, I noticed that `range.default()` has a nice `finite = TRUE` argument, but it doesn't actually apply to Date or POSIXct due to how `is.numeric()` works. ``` x <- .Date(c(0, Inf, 1, 2, Inf)) x #> [1] "1970-01-01" "Inf" "1970-01-02" "1970-01-03" "Inf" # Darn! range(x, finite = TRUE) #> [1] "1970-01-01"

I have a field called Fax in my model. I store it as a 10-digit number with no other characters but I display it as a nicely formatted phone number. I have a validation on it like this: validates_format_of :Fax, :message => ''number should be formatted using (XXX) XXX-XXXX'', :with => /^\(\d{3}\)\ ?\d{3}-\d{4}$/ If I put 1234567890 (10 digits) in my field, the

A tiny nit-pick: Seems to me that end date = NA would mean the event has not yet ended, whilst Inf would mean that the event is known to never terminate, ie: an eternal fact, or physical law.

Rails extends Ruby with mattr_accessor (Module accessor). As Ruby''s attr_accessor generates getter/setter methods for instances, mattr_accessor provide getter/setter methods at the module level. In below example, you see that mattr_accessor declared in the class context of LookupContext. It''s declared in class, not module. However, modules are defined in LookupContext, for

R developers, The "tzone" attribute is stripped from a POSIXct object when the subscript command is called ("[.POISXct"). This results in dates being printed in the locale specific format after a subscript operation is applied to a POSIXct object which has cause several problems for me in the past. Here is an example of this problem under R 1.9.1: > x <-

This rule does not seem to be widely followed by Clang today. Looking at Parser and Sema, many getters (0 argument functions with names matching /^get[A-Z]/) return mutable references to long-lived objects. Looking through Decl.h, things are a little different: we rarely return references, but do frequently return pointers that provide mutable access to contained objects. On Tue, Mar 4, 2014 at

I used read.dta() to read in a Stata 9 dataset to R. The "Sex01" variable takes on two values in Stata: 0 and 1, and it is labeled "M" and "F" respectively, analogous to an R factor. Thus, read.dta reads it in as a factor. Now, I wanted to see what this variable *really* is, in R. For instance, sometimes R converts a 0/1 variable into a 1/2 variable when it considers

In my project I have a group of foreign types (C++ classes) that I want to use, but don't want to represent as structs within LLVM. For example, for each field in each C++ class I have a setter and getter function that I'd like to use. The setters and getters are "extern C" functions to avoid problems with C++'s name mangling. After going over the documentation it

Hi, I can''t find how do i created a getter and setter property for a non db property. what i have done isnt working, i have a cnt mass assign error. Here is what i''ve done: attr_accessor :creator_is_participant def creator_is_participant @participe end def creator_is_participant=(participe) if participe == true @participe = true else @participe

Hey.. So I have a model that has a lot of number fields. Each of these go through a process when read in and read out to add/remove commas (between every three numbers) to make them more readable. The getter I currently have is like this: def sale_price Listing.insert_commas(read_attribte (:sale_price)) end and the setter is: def sale_price=(price) write_attribute(:saleprice,

Hi everyone, just wanted to ask what's the smartest/recommended way of defining getter and setter function *shortcuts* (i.e. something like "[", "[<-") for Reference Class objects? Or is it desired to not use this stuff, but define methods like 'obj$getSubset(row=1:3, col=1)' and 'obj$setSubset(value=x)' instead? I have some example code that might

There are datatypes that need to be converted back and forth from a string representation: they need to be parsed both coming from the database, and coming from elsewhere like views. Dates are an example, and I recently needed to implement a more forgiving converter for decimal numbers. So we have here at least two flows of execution, for example: post.date = "22-jan-2007"
