Consider the following example: # substitute a with b in the indicated function. Seems to work. > z <- substitute( function()a+1, list(a=quote(b)) ) > z function() b + 1 # z is an object of class call so use eval # to turn it into an object of class expression; however, # when z is evaluated, the variable a returns. > eval(z) function()a+1 Why did a suddenly reappear again

This bug report is mostly a note to myself to track this down: In the version of the Cygwin bash shell I'm currently using, Rterm does not detect that it is being run interactively, so it switches into batch mode, and lots of things stop working. >$ bash --version >GNU bash, version 2.05b.0(1)-release (i686-pc-cygwin) >Copyright (C) 2002 Free Software Foundation, Inc.

Just for fun (and actually because I would use it too) I wrote a version of the "paste" menu command that assumes the clipboard contains a transcript, and just pastes the commands from it into the R console window (Windows GUI only). So, if something like this: > foo <- + 33 > foo * 3 [1] 99 > foo [1] 33 is on the clipboard, then the "paste commands" menu

I was trying to create a function with a value computed at creation time, using substitute(), but I got results I don't understand: > this.is.R Error: Object "this.is.R" not found > substitute(this.is.R <- function() X, list(X=!is.null(options("CRAN")[[1]]))) this.is.R <- function() TRUE > # the above expression as printed is what I want for the

Hi everyone I've been playing with do.call() but I'm having problems understanding it. I have a list of "n" elements, each one of which is "d" dimensional [actually an n-by-n-by ... by-n array]. Neither n nor d is known in advance. I want to bind the elements together in a higher-dimensional array. Toy example follows with d=n=3. f <-

Hi, I need to read in some files. The file names contain come meta characters such as @, #, and white spaces etc, In read.csv, file= option, is there any way that one can make the function to recognize a file path with those characters? Thanks Johnny [[alternative HTML version deleted]]

Does anyone have something like tapply that is extremely fast for matrices when there is a very large number of levels of the grouping variable? I'm referring to, for example, tapply(x, grouping.variable, function.operating.on.submatrix) where x is a matrix and the submatrix is a subset of the rows of x. The grouping variable's length equals the number of rows of x. -- Frank E

I'm trying to create a language structure that is a call to a function with a number of arguments that is only known at run time. I do this by using repeated indices to expand out a call with a single argument. However, when I change one of the arguments, all are changed. I don't see the same behavior when I initially create a call with multiple arguments. Even more strangely,

Tony, I don't understand what you mean. Could you give an example? > -----Original Message----- > From: Tony Plate [mailto:tplate at blackmesacapital.com] > > ...

...ble with S-Plus or prior versions of R then I would go even further and make all subscripting behave like this. (If that were to be the way R goes then, of course, some thought would be required on how to smoothly transition to it.) --- Date: Mon, 27 Oct 2003 21:49:44 -0700 From: Tony Plate <tplate@attglobal.net> [ Add to Address Book | Block Address | Report as Spam ] To: <r-devel@stat.math.ethz.ch> Subject: [Rd] proposal for "strict" versions of subsetting operators I'd like to propose adding "strict" versions of the subsetting operators "[&quot...

Hi! Is there a possibilty in R to carry out LOCF (Last Observation Carried Forward) analysis or to create a new data frame (array, matrix) with LOCF? Or some helpful functions, packages?
