Multiple Groups Assigned to a File
I'm new to this group so I hope that this is the right place to ask this question (if not, let me know): We are setting up several Samba servers and we've run into a problem with file permissions. We've have a few shared folders that we'd like for some GROUPS to have read/write access and other GROUPS to have only read access. I cannot figure out how to do this because

have to point it out again: a distribution question
Stock returns and other financial data have often found to be heavy-tailed. Even Cauchy distributions (without even a first absolute moment) have been entertained as models. Your qq function subtracts numbers on the scale of a normal (0,1) distribution from the input data. When the input data are scaled so that they are insignificant compared to 1, say, then you get essentially the

an interesting qqnorm question
Hi, r-gurus: I happened to have a question in my work: I have a dataset, which has only one dimention, like 0.99037297527605 0.991179836732708 0.995635340631367 0.997186769599305 0.991632565640424 0.984047197106486 0.99225943762649 1.00555642128421 0.993725402926564 .... the data is saved in a file called f392.txt.

How does this work? I don't get how to handle

Q: sort a matrix by picking up columns?
Hi, I am wondering how to write a function which sorts a matrix by giving a vector of column numbers. Suppose we have a matrix (or data frame) "Mat" and I want to obtain order(Mat[,1], Mat[,3], Mat[,6,], Mat[,8], Mat[,10], Mat[,13]) in order to sort the matrix by those columns. Is there a way to write a function so that I can give a vector of the column numbers c(1,3,6,8,10,13) and do

Rdbi and ODBC
I have been using RODBC for a while with no complaints (R 2.0.1 patched under WinXP), then I saw a link (http://grass.itc.it/statsgrass/r_and_dbms.html) showing that Rdbi claims to run a query in 5 seconds that takes RODBC 4.3 minutes. That was hard enough for me to believe that I wanted to try some tests myself, but I cannot get Rdbi to connect to my ODBC database. Here is what works for RODBC

GRASS/R interface problem
Hi all, In my version of the R package GRASS (pre-4) I only manage to export an R object to GRASS with the name "akspl" which, if I am not wrong, is only a sample name in the example(). It goes that way: rast.obj->akspl rast.put(G, akspl, lname="rast.obj", ...) Is that a known problem or have I done something wrong anywhere? Miha Staut

I can login to my MySQL databases from any shell and directory, so the problem is probably not there. Here's an example of what I'm doing: R> odbcConnect("test",

mount a share on a W2k server
Hi everybody, excuse me when I ask something maybe 100 times discussed in this newsgroup, I try to mount a share on a W2k server box with samba (from a Fedora 2.6.5 machine) without success. Doing the same with a NT Server machine in the same LAN works perfectly. It seems that it's a problem of the password (encryption ?? digitally sign communications are disabled !!). [root@hase root]#

forced fsck (again?)
hello everyone. i guess this has been asked before, but haven't found it in the faq. i have the following issue... it is not uncommon nowadays to have desktops with filesystems in the order of 500gb/1tb. now, my kubuntu (but other distros do the same) forces a fsck on ext3 every so often, no matter what. in the past it wasn't a big issue. but with sizes increasing so much, users are
