similar to: RE: [R] List of functions with debug() and trace()

The other day I was working on an example which used tempfile() to create file for use by the graphics device. And while I love tempfile()---as it is portable and clever and the files get cleaned by R and all that---I noticed one missing feature I would like to see: beside a starting name pattern, and an optional directory, an 'file extension' argument would be nice to have. As e.g. in

Hi, OK, if you try to explicitly make them generic, you are told that they are implicitly already generic: > setGeneric("is.finite", function(from, ...) standardGeneric("is.finite")) Error in setGeneric("is.finite", function(from, ...) standardGeneric("is.finite")) : "is.finite" is a primitive function; methods can be defined, but the

Here's an update of my rawConnection() implementation. In addition to providing a raw version of textConnection(), this fixes two existing issues with textConnection(): one is that the current textConnection() implementation carries around unprotected SEXP pointers, the other is a performance problem due to prolific copying of the output buffer as output is accumulated line by line. This new

Full_Name: Lars Hansen Version: 2.1.0 OS: SunOS 5.8 Submission from: (NULL) (207.66.36.189) Hi, S4 method displacth does not work for the two generic functions 'is.finite' and 'is.infinite'. It turns out that the C functions 'do_isfinite' and 'do_isinfinite' in src/main/coerce.c are missing a call to 'DispatchOrEval' (see do_isnan). Added in the call

These functions are not generic according to the help page. The same page says explicitly that is.nan is generic. Where did you get the (false) idea that they were generic?

This is of course an incorrect usage, which I've trapped at R level, so as to give an informative warning.

The Rprofmem facility is currently enabled only if the configuration option --enable-memory-profiling is used. However, the overhead of having it enabled is negligible when profiling is not actually being done, and can easily be made even smaller. So I think it ought to be enabled all the time. I've attached a patch doing this, which also makes a number of other improvements to Rprofmem,

We have an excellent opportunity to improve the accuracy by

A colleague sent me the following: If you specify probabilities in the 'sample' function and forget to type 'prob=...', then you get nonsense. E.g. sample(1:10,1,c(0,0,0,0,1,0,0,0,0,0)) does not filter '5', while sample(1:10,1,prob=c(0,0,0,0,1,0,0,0,0,0)) does it correctly. I wish this would return an error because the

OBJECTIVE: To update source(..., print.eval=FALSE) to not use withVisible() unless really needed. This avoids unnecessary increases of reference counts/NAMED introduced by withVisible(), which in turn avoids unnecessary memory allocations and garbage collection overhead. This has an impact on all source():ed scripts, e.g. pre-allocation of large matrices to save memory does *not always* help in

Dear R-devel, I don't think this is expected : foo <- function() "hello" trace2 <- function(fun) trace(fun, quote(print("!!!"))) base::fun # Object with tracing code, class "functionWithTrace" # Original definition: # function() "hello" # # ## (to see the tracing code, look at body(object)) `untrace()` has the same behavior.

I tried to run gdb in linux with emacs But could not even run a simple example in the writing extensions tutorial. The execution history is as follows. Gdb worked fine for other debugging such as C++ codes. Thanks Han I started R at echo of emacs by typing (also tried other methods mentioned in the tutorial both in emacs and xterm.)

Hi Tomas, The doc indeed describes `what` as "the name, possibly quote()d, of a function to be traced or untraced". This is a good argument not to change the function and make it behave more like debug. However the doc also tells us "A call to trace allows you to insert debugging code (e.g., a call to browser or recover) at chosen places in any function" and "The trace

I've just implemented a generalization of R's text connections, to also support reading/writing raw binary data. There is very little new code to speak of. For input connections, I wrote code to populate the old text connection buffer from a raw vector, and provided a new raw_read() method. For output connections, I wrote a raw_write() to append to a raw vector. On input, the mode

The patch below adds support for custom HTTP headers in download.file() and url(). My main motivation for this is performing basic http authentication. Some web sites do not support embedding the credentials into the URI itself, they only work if the username and password are sent in the HTTP headers. In fact specifying the username and password in the URI has been
