Error in substring: invalid multibyte string
Thanks for the quick response Ivan. readLines with encoding='latin1' works
for me (on Ubuntu).
However I was more concerned with the inconsistency in results between
substr and regexpr. I was expecting that if one of them errors because of
an unknown encoding then the other should as well. Even better, if regexpr
works, why shouldn't substr work as well?
Incidentally the analogous

mapping of colornames into hsv?
I couldn't find this in online help or the archives:
Is there any R function or object giving the mapping of the colornames as
given by colors() into the hsv() model?

standing ovations
I think this is a moment to lean back from daily business, details or
whatsoever and appreciate the impressive achievment of Ross, Robert and the
R-core team. Incredible!
They created an impressive and extremely useful software, for teaching,
research and more. Besides these direct practical benefits, I think this
project is more: it gives an outstanding example of international

long character data
Hi,
When trying to generate very long strings, my R hangs without any error
message, even if given much memory.
# e.g.
x <- character(10)
for (i in 1:10) x[i] <- paste(1:1000, collapse="abc")
paste(x, collapse="")
# or directly
paste(1:10000, collapse="abc")
Am I violating any max(nchar(character())) or is this a bug?

Bug: time complexity of substring is quadratic as string size and number of substrings increases
Hi all, (and especially hi to Tomas Kalibera who accepted my patch sent
yesterday)
I believe that I have found another bug, this time in the substring
function. The use case that I am concerned with is when there is a single
(character scalar) text/subject, and many substrings to extract. For example
substring("AAAA", 1:4, 1:4)
or more generally,

R as a server in client server computing
I like to have a continuously running R process, which can receive a
dataframe from a client (over TCP/IP), does some processing, and sends some
data back. What is the prefered way to do this? Using the socket interface?
Using omega's CORBA stuff?
Does anyone has example code for doing so?
Thanks for any help

Can anyone give advice how to interactively exchange data between R and
SQL-Databases like DB2, ORACLE, MS-SQL-Server ?
If the answer is: 'currently not', this would be information for me as well.
I will summarize to the list.

paste with a matrix

below is a function which pastes a matrix, but uses parsing

Does anyone know a more standard solution to pasting a matrix?

Hi,
can anyone help with two questions concerning persp?
(1) Is there a function in R to project points onto a persp() plot, as is in
S+ (perspp() I think) ?
(2) How can I label and tickmark axes x,y and z in a persp plot?
(I am still using RW065)
