Hi all, I'm getting the following error from substring: > substr("<I>Jens Oehlschl\xe4gel-Akiyoshi", 1, 100) Error in substr("<I>Jens Oehlschl\xe4gel-Akiyoshi", 1, 100) : invalid multibyte string at '<e4>gel-A<6b>iyoshi' Is that normal / intended? I've tried setting the Encoding/locale to Latin-1/UTF-8 but that does not help. nchar

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

I've noticed quite a few messages relating to large data sets bedeviling R users, and having just had to program my way through one that actually caused a "Bus error" when I tried to read it in, I'd like to ask two questions. 1) Are there any facilities for aggregation of data in R? ( I admit that this will not do much for the large data set problem immediately) 2) Is there any

Yesterday I asked for help about read.table with a CSV file. I received the following help. As always many thanks for the prompt responses. Now I load my csv file in a text editor ( pfe) and delete all spaces. My original mail is at the end. From: Peter Dalgaard BSA <p.dalgaard at biostat.ku.dk> Do you have spaces before the commas in your file? > Yes, number , space,

I just tried to batch-start rgui.exe (not rterm.exe) in a way, that it read.table()s data from a file with changing filename. As I understand no command line parameters are available for that, so instead I tried to pass the filename to an approbriate .RProfile, which works roughly, BUT ## this is my %R_USER%\.RProfile im <- read.table("d:/temp/im/temp.csv", header=TRUE,

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 Regards -- Dr. Jens Oehlschl?gel-Akiyoshi Analyse MD FACTORY GmbH Gr?nstr. 15

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?

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.

Hello! Is there someone already working on an implementation of Splus' chull() function for R? If not, I would like volunteer to try it. For my "Diplom" I implemented convex peeling in C (some time ago), using an O(n log(n)) algorithm, so it probably will prove relatively easy to use that code for a R-function. Well, as least as easy as any programming tends to be. :-) Detlef

Hello, I would like to know if the ARM architecture is well supported. At Xen.org it is mentionned in available architectures, but does it work really well ? I''m looking at CPU like "Tile64" from Tilera : http://www.tilera.com/products/processors/TILE64 The wiki http://wiki.xensource.com/xenwiki/XenARM doesn''t seem to be up to date. Is it ? Any advice ?
