similar to: R , apache and PHP

I've developed a web application in PHP and R my script is <?php ... exec("R CMD BATCH --silent /home/marcello/R_in/myfile.bat /home/marcello/R_out/myfile.out"); ... ?> This script execute in R batch mode and write the myfile.out. On Win2000 the similar script is ok, but on linux I've a problem. I suppose is a permession problem because the same script on shell

Dear all, I wrote a simple script in order to put together some functions and method to be executed on various files I am trying to have to possibility to call the script changing few parameters in order to use the different files. I succeeded partly using the function method. However in my script I call the sink() function in order to output the results to a .txt file. When using the function the

Hi all, Here''s what I''ve come up with so far for a pure Ruby Dir.glob for MS Windows. It almost works. The problem right now is the [] notation, which I''m not translating properly into a regex. I haven''t started on the ''**'' notation yet either, but I figure that''s more of a control flow issue. Feel free to disagree with me and/or

Dear all, Maybe, I am doing something wrong, but using R-2.5.0 on my Intel-Mac, I have problems using function callNextMethod() in method initialize. I am loading the following code as file "testS4.R": setClass("baseClass", representation(myname = "character", mydir = "character", "VIRTUAL"),

Dear R-users, I am trying to use the grep function to test whether a particular string is of the form "n.../mydir/myfile.mytype.myext". Anything between n and mytype could vary, and anything after mytype could vary. I tried to proceed by steps to build my regular expression... but I do not really understand why the last call of the following code do not work. Any help would be

Is it possible to regenerate the index files, on other conditions than the mbox file being read? For instance, it would be nice if I could regenerate the index for a specific mbox whenever procmail delivers mail to it. If theres no existing solution, would it be possible to make a small script with something like "nc" that could send an imap command to dovecot, so that dovecot would

Since I am using dovecot I do not have courier installed, but Courier had a very handy tool for making maildir folders called `maildirmake` which I used in some automated backup scripts. How do I duplicate maildirmake in dovecot? for example: #!/bin/bash # v1.2a Testing for new dovecot install # Archive mail from folders without [0-9]{4} Maildirs # after they are 21 days old to a yearly folder

Hi, I believe this is kind of a long standing bug though. In R-3.0.1, but this also happened in previous versions, the long version '--outdir' is not recognised: For `R CMD check --outdir=mydir pkg_0.1.tar.gz` we get: Warning: unknown option ‘--outdir=mydir’ But with `R CMD check -o mydir pkg_0.1.tar.gz` we get: * using log directory ‘/home/renaud/Documents/projects/mydir/pkg.Rcheck’

Hello! I want to detect some environment on a remote host (in C program, getenv()), but it is failed. Here is a little program which I try to run on a remote host with command: "#ssh myhost myecho" /* myecho */ #include <stdio.h> main (){ char *dir; if ((dir = getenv("MYDIR")) != NULL) printf ("environment is %s\n",dir);

Hello, i am using net-fs/samba-3.0.10 on an updated gentoo linux on x86 machine. recently i was using some older version, probably 3.0.9 i didn't change my smb.conf but now printing from windows 98 clients does not work anymore. the errormessage on win98 is (translated from german): Error when writing on \\master\stylus1160 vor printer (EPSON Stylus Color 1160): The network printer ist not

Hi, all, I'm looking a utility for removing a directory from within R. Currently, I'm using: foo <- function(...) { mydir <- tempdir() dir.create(mydir, showWarnings = FALSE, recursive = TRUE) on.exit(system(sprintf("rm -rf %s", mydir))) ## do some stuff in "mydir" invisible() } However, this is assumes "rm" is available. I know of

Hello, I have a strange problem affecting samba-3.0.10-1.4E.12.2 on a Red Hat Enterprise Linux AS release 4 system. We have a multi-domain configuration here at University of Verona (Italy). We use Samba as PDC for several faculties. Each faculty has its own daemon instance and its own smb config file: [root@ldapvr1 ~]# ls /etc/samba/smb.* /etc/samba/smb.conf

Hi, all, I've been converting code from S-Plus ("S" for short) to R for a few weeks. Here are some differences I've found, aside from the big well-known ones (scoping, models, data storage) and the contents of Kurt Hornik's FAQ section 3.3.3. Let me start with the ones that seem like serious bugs or deficiencies: 1) LETTERS[c(NA,2)] in S is

Hi List, I am reading table from postgres database into R session using RJDBC, table contains 150 columns and 200000 rows. Sample code is as below, which works fine with smaller tables. ######################################################################## db_driver <- mydir$db_driver db_jar_file <- mydir$db_jar_file db_server <- mydir$db_server db_server_lgn <- mydir$db_server_lgn

Hello everyone, I'm doing some tests with ACL's and even though I can create a "default" ACL for a directory (that includes "rwx" for the default owner), when I finally create a file wihin that directory the execute bit is chopped off: [joe at machine ~]$ mkdir mydir [joe at machine ~]$ setfacl -d -m u::rwx,g::-,o::- mydir/ [joe at machine ~]$ cd mydir [joe at

Hi All, This might be simple question, I need to retrive data for modelling from the databases. Eveytime date values changes so I countnot fix date value in the code, it is required to pass as parameter. When I pass the date as parameter, it throws error.

Hello, I am using rsync for the first time. I have rsync 2.6.5 running on Solaris 9. It was built with gcc-2.95. We are experiencing a reverse lookup host error in rsyncd.log when the client with ip addy 180.X.XX.XX tries to access rsync on my Solaris box. 2005/08/11 14:30:13 [18092] rsync denied on module log from unknown (0.0.0.0) 2005/08/11 14:30:54 [18094] name lookup failed for 0.0.0.0:

Hi NG, I want to do incremental backups to a remote server running rsyncd (because daemonless transfer via ssh often hangs!). In contrast to transfer via ssh (without remote rsyncd) this doesn't seem possible, or do I miss something? Imagine I want to incrementally backup `mydir' to the backup space `backup' on e remote server `alpha' running an rsync daemon. rsyncd on

Hi: I have an application where there is a single file-server and approximately 500 clients that are writing a continuous stream of moderate-sized data files. We have been using samba for this, but the problem is each smbd process on the server side ends up chewing up 50-60 megs worth of memory after a while. With 500 clients that takes a good chunk of the memory away :-) I am exploring

A new package "g.data" is available on CRAN, to create and maintain databases that work more like the S-Plus model. Here's the official Description for g.data (v1.2): Create and maintain delayed-data packages (DDP's). Data stored in a DDP are available on demand, but do not take up memory until requested. You attach a DDP with g.data.attach(), then read from it and assign
