Hi Guy, I am having trouble graphing the following function √2Γ(n/2)/[√n − 1Γ((n − 1)/2 for the values of n between 2 and 50. i know that Γ(n) = (n-1)!, which in R is factorial(n-1) When i type that into R, using y <- function(n)..... and then plot(y,2,50), it doesnt give me anything meaningful, in fact, it comes up with a message saying something like "in gamma(n+1) ploted" or

Hello, I am relatively new to R and learning its ins and outs. As part of a website I am building, I need to read and write csv files directly from an SQL database. Basically I want to convert R variables (dataframes) into CSV format, store them as another R variable (as a properly formatted text string suitable for csv reading) and then send this to one row in a database. The SQL part is fine,

Dear R users, Can anyone please tell me how to generate a large number of samples in R, given certain distribution and size. For example, if I want to generate 1000 samples of size n=100, with a N(0,1) distribution, how should I proceed? (Since I dont want to do "rnorm(100,0,1)" in R for 1000 times) Thanks for help Debbie

I have a such problem. I have samba 3 as a PDC with ldap as a authentication backend.

I have a reproducible intermittent error large site - "The specified network name is no longer available". This happens when copying large files. Below is part of log level 10 output & strace. Sorry for the long posting. I will probably need to put the loglevel 10 attached to a bugzilla - but thought I would try the lists initially. RHEL4 samba-3.0.25b-1.el4_6.4

Dear R users, Does anyone know how to write a function involving derivative? i.e. I want to implementing Newton's method in R, so my function is something like x<- x-y/y' I am not sure how to write y' in my function. Can anyone help? In addition, if I want to implementing newton's method several times, what code should I use? Currently, I use the following code.

I have two samba servers running Ubuntu 10.04 Samba Version 3.4.7 One server acts as domain controller and stores user ids in a .tdb Somehow I've ended up with a duplicate user name.

Hi there, Is there a utility to create an EXT3 file system image from directories? Just like the mkfs.jffs2 which creates a JFFS2 file system image from directories? The "mke2fs -j" only creates the bare bone file system, what I want is to build an image with pre-built content. Thanks, Debbie

Hey Guys, i have the sample variances for 1000 samples, and i want to fit it to a chi-squared distribution. after making a loop for the simulation initially, i have the following code to compute the variances samples = replicate(n, rnorm(m, 0, 1), simplify=FALSE) variances = sapply(samples, var) summary(variances) can someone please help me fit this to a chi-squared distribution with n degrees

Hi All, I have two boxes running samba 3 on fedora2. Box A is the primary domain controller & smb file server and we (a primary school in QLD, Australia) can login from our windows 98 machines with samba verifying usernames & passwords. This week I've been trying to setup Box B as a print server (and eventually limit students' printing sprees). I've connected the

We are getting ready to implement Windows 2000 to approximately 800 users who need to access HP and Sun UNIX servers. We looked at Microsoft's Services for Unix and didn't like it. Hummingbird's NFS Maestro was too expensive. One of our departments (40 users) has been using SAMBA for about a year now. However, I am required to find out where we can obtain support and to see if I

Hi, I have a Red Hat AS3 PDC server running Samba 3.0.0. I have Linus workstations and Windows 2000 workstations. Some not all of my Windows 2000 workstations will not let any user login to the domain. Says username or password is incorrect. If you create a local user account on the workstation and login as that user you can get to all shares and there are no problems. I also have a problem with

Hello - I never heard back on this and continue to experience this bug. Can someone help me to locate the patch for this so that I can be sure it's included in my source? It's not happening on every boot, but about every other or third. And just as described in the bug report (the boot works OK, but at the end rather than GDM starting nicely, I get a "fuzzy" screen and the

Now that I've been enlightened to the terrible write performance of ext3 on my new 3Ware RAID 5 array, I'm stuck choosing an alternative filesystem. I benchmarked XFS, JFS, ReiserFS and ext3 and they came back in that order from best to worst performer. I'm leaning towards XFS because of performance and because centosplus makes kernel modules available for the stock kernel.

Hello All, I''ve seen this topic but it seems no one has post a response. I''m using periodicalUpdater to display live content queried from a database. Sometimes the result can be thousands of rows and before it finishes processing (displaying as a visual indicator) all the data, the next request is sent to the server. I''d like to have a periodicalUpdater whose
