similar to: namespaces and assignment: a problem/question

Dear list, I received the response below from the package author of 'debug'. I post it to the list, with Mark's approval, in case it is useful to others too.

Hello, pointed to the article "Debugging Without (Too Many) Tears" of Mark Bravington in Rnews Vol 3/3, December 2003 there is a package mvbutils mentioned. So I started to install this package from within R > install.package(mvbutils) I receive an error essage that this package is not found! Is due to a merge,removal or rename of this package? When I try to follow this

Hi Jannis [I'm the author of package debug... I know this is 6 months after your query, sorry-- but I don't subscribe to R-help, and you didn't post to the maintainer! I'm primarily sending this to close off the thread.] > when I use the package debug, mark a function with mtrace() and enter > into the browser like mechanism of debug a window displaying the code of >

Hi, everyone. I am using a fair amount of closures in my code. Problem i am experiencing is i cannot figure out how to mtrace functions defined within a function. There must be some way to name such function for mtrace to see it and let me step into it. For example, say i have code mymodel<-function(){ data<-numeric(0) build<-function(){ data<<-1 } m<-list()

Bill Venables expected howls of protest about deprecation of underscore for assign. Here's my one-and-only howl on this point: (1) I don't like <- as an assignment operator, because it creates an ambiguity with comparisons: I can write "x+1", "x-1", "x<1" but not "x<-1". However, I guess it's a bit much to expect the entire R/S

Dear useRs, I am experiencing very strange error with Mark Bravington's package "debug". I haven't seen them before. Here is the sample session > library(debug) Loading required package: mvbutils MVBUTILS: no "tasks" vector found in ROOT Loading required package: tcltk Loading Tcl/Tk interface ... done > x<-function() return(1) > mtrace(x) > x() Error

Please use the CRAN versions, not the ftp versions which are now out-of-date. Both packages are on base CRAN now, but may not have propagated to all mirrors yet. (But thanks to Gerald for responding-- I had de-subscribed from R-help.) For anyone using the HANDY package (a Windows-specific package which includes a non-C DLL, so I can't CRAN it): I'll post an updated version on the ftp site

A number of users have spotted a terminal problem with the 'debug' package under R2.4.0, along the lines of > mtrace(x) > x() Error in attr(value, "row.names") <- rlabs : row names must be 'character' or 'integer', not 'double' This arose from a bug in 'rbind.data.frame' in R2.4.0 itself. The bug is fixed in R2.4.0 patched, so the

Hello I need some help in figuring Bravington’s debugger out. Ok I have 2 functions, fun1 and fun2 saved in a ASCII file say filename is funs. Fun1 has a loop which calls fun2, fun2 has a loop which fails and I need to find out the value of the variables of the fun2 and fun1 loops at the specific iteration that fails. Both fun1 and fun2 loops will iterate thousands of times so line by line debug

'getAnywhere' is not reporting methods when there are periods in the class name or the generic name (in R-devel). > getAnywhere( 'predict.loess') A single object matching 'predict.loess' was found It was found in the following places registered S3 method for predict from namespace modreg namespace:modreg with value <<...>> > getAnywhere(

A bit late for Santa, but on my wish-list nevertheless: is there any chance that "scan" and "readLines" could be extended to take a parameter "until" or "EOF.marker", which would be a character string that (if encountered while reading) would cause the reading to stop, just as if an end-of-file had been found? [But leaving a connection open, so that

Thanks-- as Duncan Murdoch also noted, R_HISTFILE can be used to solve my problem, as below. BTW it's not easy to find out about R_HISTFILE in the help system or manuals, though, unless you already know it exists-- it only seems to be described under startup options, not things to do with history. However, Duncan's reply did hint at an inconsistency, in that savehistory() defaults to

Hmmm-- still looks like a bug to me! But as I don't want to hog the airwaves, here's my last summary on this point, with a question: [Bravington] #> Prediction from the original data was just an example, of course; my general #> proposal is that inactive factor levels in the prediction set should be #> dropped. I don't see how this could ever cause inconsistent behaviour

When something gets printed by the "print.default" function, any extra attributes are printed without regard to their class attribute (if any). For example: > x <- 1:3 > attr( x, 'other') <- factor( c( 'cat', 'dog')) > attr( x, 'other') [1] cat dog Levels: cat dog > x [1] 1 2 3 attr(,"other") [1] 1 2 which is perhaps

Hi Mark: I had also used sample and tabulate for generating multinomial and found it to be quite slow. So I had written a multinomial random numbers generator based on the GENMUL subroutine from "ranlib", which in turn is based on the algorithm from Luc Devroye's book on "Non-Uniform Random Variate Generation" You may want to compare this with your hybrid algorithm and

The function 'getAnywhere' crashes if given a non-existent name containing a period: > getAnywhere( 'nomethod.noclassforme') Error in get(x, envir, mode, inherits) : variable "nomethod" was not found However, 'getAnywhere' behaves gracefully if the non-existent name lacks a period: > getAnywhere( 'nomethod') no object named `nomethod' was

Dear group I use "restart" in part of my code, in a way that's not easily changed to "try". As I convert code from R1.5.0 to R1.6.1, I'm getting ugly messages; the help system says to contact r-devel, so here I am. This one's a bit complicated-- sorry! The context is inside a debugger (I have an R and S debugger that offers stand-alone code windows, line numbered

In R-1.7.1, I used to be able to append a character vector to a 'tklistbox' with e.g. listio <- tklistbox( tktoplevel(), font='Courier', height=20, width=20, setgrid=TRUE) tkinsert( listio, 'end', letters[1:3]) tkpack( listio,side='left', expand=TRUE, fill='both') and three items would be added to 'listio'. This doesn't work in R-devel-- it
