Hi. I have a small problem with the custom type I am working on. I define method ''evaluate'' which is called after all data is been collected. Here it is: module Puppet newtype(:test) do newparam(:name) do end newparam(:listen) do defaultto "silent" end def evaluate puts "evaluating..." return super.evaluate e...

Hello, and sorry if this is already explained somewhere. I couldn't find anything. R (2.3.1, Windows) seems to perform some kind of lazy evaluation when evaluating defaults in function calls that, at least for me, leads to unexpected results. Consider the following, seemingly equivalent functions: > foo1 <- function(x, y=x) { + x <- 0 + y + } > foo1(1) [1] 0 > foo2 <- function(x, y=x) { + y <- y + x <...

...<- function(er) { foo(er) } > foo(a) [1] 5 > bar(a) Error in eval(expr, envir, enclos) : object "a" not found Now, regarding the "bar(a)" call, this is my understanding of what happens, hoping someone will correct me where I'm wrong. 1) bar is called. Its evaluation frame contains the association "er=a". 2) bar calls foo. So foo is called, and its evaluation frame contains the association "expr=er", with enclosing environment the local environment of bar. 3) foo calls eval. 4) eval starts by evaluating "substitute(expr)"...

...pre-call and post-call shims to capture the arguments and return value, respectively. I can think of only one fundamental conceptual obstacle to this approach: R functions are not necessarily referentially transparent. The arguments received by a function are not values but promises. They can be evaluated directly ("standard evaluation"), after applying arbitrary syntactic transformations ("non-standard evaluation", aka NSE), or not at all. Therefore, if you peek at the values of function arguments before evaluating the function, you risk altering the semantics of the program...

Dear R Help folks -- I have been trying to put together a list of the steps or stages of R function evaluation, with particular focus on those that have "standard" or "nonstandard" forms. This is both for my own edification and also because I am thinking of joining the world of R bloggers and have been trying to put together some draft posting that might be useful. I seem to have an...

Full_Name: Jelle Goeman Version: 2.4.0 OS: windows XP Submission from: (NULL) (145.88.209.33) Hi, I like to use optimize() to optimize functions whose evaluation is costly in terms of computation time. The Brent algorithm which is implemented in optimize was designed to optimize a function with as few function evaluations as possible. Therefore it bothers me that optimize() always evaluates the function twice at the optimal value. This can be seen for...

I'm not sure if this is a known peculiarity or a bug, but I stumbled across what I think is very odd behavior from delayedAssign. In the below example x switches values the first two times it is evaluated. > delayedAssign("x", {x <- 2; x+3}) > x==x [1] FALSE > delayedAssign("x", {x <- 2; x+3}) > x [1] 5 > x [1] 2 The ?delayedAssign documentation says that "after [evaluation], the value is fixed and the expression will not be evaluated again."...

Hi all, I have evaluated new weighting schemes along with their existing counterparts in Xapian to compare and see which one does better job. Also, I have put together all the results files for easy access here: https://github.com/ivmarkp/xapian-evaluation/tree/evaluation/run and a README for getting started with xapia...
