Dear developers,
would it be feasible to add an "..." argument to the "median" generic
function (and by extension also to "median.default")?
That would allow the implementation of "median" methods for data structures
that require optional arguments, as is already supported by the "mean"
generic
Hi Keith,
The problem is not with tempfile(), and is not really a problem of whether a
file exists or not. The problem is that system2() does not put the contents
of stderr into the file. Here is a demonstration without the use of
tempfile(), using a pre-existing output file:
klediment:~ dante$ e
Looking at help for tempfile,
"tempfile" returns a vector of character strings which can be used as
names for temporary files.
and
For "tempfile" a character vector giving the names of possible
(temporary) files. Note that no files are generated by "tempfile".
try a file.create(t) after
According to ?system2, I should be able to direct the output of STDERR to a
file by giving the filename as a character vector to the "stderr" argument.
But here is what happens.
Given a ruby script test.rb (with its executable bit set):
#!/usr/bin/env ruby
STDOUT.puts "stdout"
STDERR.puts "stder
The problem here is that the primitive for `$` does not use standard R
evaluation on its second argument, so when it is selected as the next
method the call is effectively x$name regardless of the original call.
If possible, I would avoid such cascaded calls of methods for `$`,
precisely becau
`[[<-`, that is. Right, the primitive code is not retaining the
subclass information.
Should be fixed in r-devel and 2.12 patched from revision 53547.
Thanks for the catch.

Hi,
Today we've seen the following problem with the R-2.12 that we use

A recently patched [[ for environment class returns a blank environment for a
