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 best solution is to install the patched version. This is painless, at least for Windows, since a bi...

...me(x=2)),data.frame(x=3)) I'm providing a new implementation (and documentation) of make.names which fixes these problems. The uniqueness part is handled by make.unique, a useful function in its own right. For example, the following code in rbind.data.frame: while(any(xj <- duplicated(rlabs))) rlabs[xj] <- paste(rlabs[xj], 1:sum(xj), sep = "") could be replaced by: rlabs = make.unique(rlabs) Another way to fix the first problem, by the way, would be to allow quoting in formulas, e.g. lm("if" ~ then, ...). Currently, when you do this it gives an error....

Hi. I recently upgraded to R version 2.4.0, and I have found that the "debug" package no longer works. In particular, when I try to debug a function, I get the following error message: Error in attr(value, "row.names") <- rlabs : row names must be 'character' or 'integer', not 'double' I have, of course, taken all the necessary preceding steps, such as issuing the commands library(debug) source("test.r") mtrace(test) test() Does anyone know how to get around this problem? Than...

Hi, For those who are interested, I have update my R benchmark (to version 1.5.0) and also to Splus 6. They are available at: http://www.sciviews.org/other/benchmark.htm. A comparison is made between Matlab (5.3 & 6), R 1.5.0, Splus 6 rel 2, O-Matrix 5.1, Octave 2.1.31, Scilab 2.6, Rlab 2.1 and OX 3.00 under Windows 2000 pro. Overall, R is not the fastest package, but it is one of the fastest... and comparison with Splus is interesting! Please, note that the benchmark tests only a few function, and also gives no information about the "richness" or "usability"...

There's a problem new to R2.4.0 when rbinding an auto-row-named data.frame to a list: > rbind( data.frame( x=1), list( x=2)) Error in attr(value, "row.names") <- rlabs : row names must be 'character' or 'integer', not 'double' Works OK with 2 data.frames or 2 lists.

Hi folks, I've been dickering around again, wasting the time away.... and today Brian Zisk (chief Vorbis Evangelist among other things) said, "Hey! We need to demo to the world on the 4th of April!" Hooo boy. Time to suck it up and bang it out. The Vorbis libs are not a problem. I'm in process of checking in my new psychoacoustics (they're real pretty!) based on
