This only happens if 'file' is a text connection, and is the expected
behaviour in that case: you cannot capture an incomplete line to a text
connection.
There seems no reason to break the documented behaviour in other cases to
change something that you consider to a bug when file=NULL and the user
does not produce complete output. It would be possible to make use of
isIncomplete()

Version: 2.6.1
OS: MacOS X; Windows XP
Submission from: (NULL) (81.243.237.235)
Last output from capture.output() is truncated if it does not end with a
carriage return:

[1] "text"
> capture.output(cat("text")) # Missing output!
character(0)

Continuation and parse
Hi gurus,
After an unsuccessful scrabble through the documentation and Jon's
excellent search facility, I am no wiser as to how R recognizes an
incomplete command line and politely raises its hand for more. The help
page for parse gives no indication that it does anything more than spit
the dummy when fed an incomplete command line, but something in there
must recognize such ellipsis.

Ideas needed on automation of R
I need some guidance on what is the best way to automate R I am aware of
Rterm.
First question: Is it true that R is not currently OLE accessible under
Windows 2000?
Second question: Is there an R command that echoes all R Console results to
a run log system file?
My first attempt to write a run log file is the example from the R Data
Inport/Export documentation.

Lazy loading... advices
Hello,
I am looking for more information about lazy loading introduced in R 2.0.0.
Doing
?lazyLoad
I got some and there is a 'see also' section that points to
'makeLazyLoading'... But I cannot reach this page.
My problem is: I recompiled a library that uses a lot of functions from
other libraries (of course I can give details if needed). I load it in my
computer: library(svGUI),

assignment in lists
Hello,
I do not understand the following behaviour. Could someone explain me what
happens?
> a <- NULL
> a$item <- 1:3
> a$item
[1] 1 2 3
> rm(a)
> a <- NULL
> a[["item"]] <- 1:3
Error: more elements supplied than there are to replace
Why do I get an error message using list[["item"]], and not using list$item?

Handling of upper/lowercase in package names (PR#2816)
Hi,
This is (presumably?) a bug in R 1.7.0 under Windows. I have not tested it
on other systems. Attachment of packages is case sensitive but not
library(), resulting in multiple loadings of the same package if the library
name is spelled differently. The following example loads the `tools'
package, once as `tools' and once as `Tools'. This behavior is the same with
all packages and

Forwarded to R-Help, because I think it could interest people following
this thread. Clearly, RServe and svSocket have different goals and very
little overlap.

How does R compares for speed?
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

Power (^) 10x slower in R since version 1.7.1... What next?
OK, I have made a little search about this "problem" that apparently occurs
only on Windows platform... (but I am sure most of you are already aware of
it): the slow down is due to the adoption of a different algorithm for pow
in mingw 3.x. This is motivated by some other changes in mingw. Here is a
quote of Danny Smith that did this change:

Detecting incomplete commands
Hello,
I need a similar behaviour as with the prompt: asking to complete incomplete
R command with eval(parse(text = ....))
Is it a way to make the difference between an illegal and an incomplete R
command in a string?
For instance:
> parse(text="ls()")
expression(ls())
This is fine!
> parse(text="ls(")
Error in parse(file, n, text, prompt) : parse error

Cross-platforms solution to export R graphs
Hello Rusers,
I have worked on a R Wiki page for solutions in exporting R graphs,
especially, the often-asked questions:
- How can I export R graphs in vectorized format (EMF) for inclusion in
MS Word or OpenOffice outside of Windows?
- What is the best solution(s) for post-editing/annotating R graphs.
The page is at:
