similar to: Kernel#system Kernel#` - Is anyone using these in Rails?

Full_Name: Gabor Grothendieck Version: R version 1.9.1, 2004-08-03 OS: Windows XP Submission from: (NULL) (207.35.143.52) The following gives an error: > `a(b)` <- 1:4 > `c(d)` <- (1:4)^2 > lm(`a(b)` ~ `c(d)`) Error in model.matrix.default(mt, mf, contrasts) : model frame and formula mismatch in model.matrix() To fix it replace this line in model.matrix.default:

I''m trying to stub(!) the Kernel.` (backquote) method and I''m having confusing (to me) results. Here''s the method I''m spec''ing: class Barcode ... def raw_barcodes self.make_temporary_copy `OcrBarcode #{self.temp_file_path}` end ... end And this is my (newbish) attempt at the spec: describe "Calling @barcode.raw_barcodes" do

I know my subject line seems odd, but I want to replace an expression—such as a variable—with its value. For example, I want to paste() some strings together, assign the result to a variable s, then use the value of s as a variable to hold another value. Something like this: import_subjects <- function (start, iterations) { for (i in 1:iterations) { # iterate from start to end s <-

Hi Folks, Can someone satisfy my curiosity (well, at least about the following query!) Reading the draft proofs of an article I've been asked to look through, I find the typesetter has set what would normally be entered as source("xyz.R") or source('xyz.R') as source(`xyz.R') i.e. it has come out with an opening backquote, then xyz.R, then a closing forward

Ben, Looking at your notes, it appears that your solution is to write your own terms() function for lme.? It is easy to verify that the "varnames.fixed" attribute is not returned by the ususal terms function. Then I also need to write my own terms function for the survival and coxme pacakges? Because of the need to treat strata() terms in a special way I manipulate the formula/terms in

Thanks to Bill Dunlap for the clarification. On follow-up it turns out that this will be an issue for many if not most of the routines in the survival package: a lot of them look at the terms structure and make use of the dimnames of attr(terms, 'factors'), which also keeps the unneeded backquotes. Others use the term.labels attribute. To dodge this I will need to create a

Dear R-devel, There is a new feature in R-devel, which explicitly refers to LISP @ operator for splicing. > The backquote function bquote() has a new argument splice to enable splicing a computed list of values into an expression, like ,@ in LISP's backquote. Although the most upvoted SO question asking for exactly LISP's @ functionality in R doesn't seems to be addressed by this

Dear all, I have the following (rather) strange problem.. For some reasons, I finally work with a variable whose name includes an R function, "a.log(z)", say. And that is a problem when I call it in a formula, for instance: > myname<-"a.log(z)" > dd<-data.frame("a.log(z)"=1:10,y=rnorm(10)) > o<-lm(y~1,data=dd) >

Hi, I am using backgroundrb to create a automated system of typo blogs.So, users can create new typo applications using web interface and all that jazz. Now..its working perfectly except one minor glitch. Since latest version of typo has a command called "typo", i simply use that command to install new typo app.And it works. def do_work(args) DIR =

I''ve done tons of searching on this so I apologize if this is one of those common knowledge things. I am relying on Kernel#` and Kernel#system to run some command line utilities in my Rails app. This worked great until I moved to Apache (win32). When running FCGI, neither of these methods work (both return nil). When running CGI, system seems to work, but ` doesn''t. I have

Dear all, When I compared the performance of some application on both a Xen domU and a standard linux machine (where domU runs on a similar physical mahine), I notice the application runs faster on the domU than on the physical machine. Instrumenting the application code shows the application spends more time on popen() calls on domU than on the physical machine. I wonder if xenlinux does some

Hi all, I am setting up some R program files for use by our DB programmers to enable them to utilize some R functions which will be called from within TCL code. R has been installed on an RHEL server and R will process the results of SQL queries against an Oracle database. In some cases, they will generate a data file to be read in and processed by R, in others they will simply make the
