Hi, there, I'd like to get a statistics to reflect the correlation of two time serials observations. for example, one time serials over time 1 to 20, and another one from same time points from 1 to 20. I need one scalar satistics as a correlation of these two observations. Thank you and have a good weekend! Jieping Zhao PhD student in Bioinformatics, NCSU Lab homepage:

I want to use read.table to input many files, each for a different year. I would like to use the macro variable 't' to refer to the exact file that I would like to input the data using read.table. How could I do this? Thank you! for (t in 1970:2005) { edge <- read.table(file="edge_t.csv", header=T, sep=",") ## I will have many rows of code following the

I'm using Samba 3.0.3 on Fedora Core 2 with OpenLDAP 2.1.29 for a backend. I'm getting to typical "The user name could not be found." error upon trying to join a Windows box. I've gone through every digest on lists.samba.org and other sites and nothing has worked yet. Any suggestions: Here's what I've done so far: 1. Installed everything via RPMS: [root@smbtest

After, oh, six months of attempts here and there to read everyone's experiences with Samba/LDAP and inability for a windows 2000/XP machine to join the domain, I finally discovered what was not working properly. In my smb.conf I put: add machine script = /usr/local/sbin/smbldap-useradd -w "%u" As instructed by many How-to's and Idealx. However, I thought to myself, %m

I have two variables in a data frame, I want to generate two additional variables. For every observations (i.e. every row), I want the first new variable 'min' to carry the minimum of the two existing variables, and I want the second new variable 'max' to carry the maximum of the two existing variables. I then want to sort the data frame by min and max, and delete duplicated rows

Gang, I've got to admit, what really sold me on debian was apt-get. And I've been resisting getting up to speed with yum. So, can any of ya point me to a good starter page, maybe one with migrators like me in mind?

Hi, I am having trouble compiling package gap http://www.hgmp.mrc.ac.uk/~jzhao/r-progs.htm on Tiger. I have installed XcodeTools 2.1. The binary version of gap currently available on CRAN has some bug and is fixed in the latest version. The message I get from R is below. Any help is greatly appreciated. best regards, Kenny Ye tar: Read 1536 bytes from - * Installing *source* package

I had yam working with ncsu.edu until the things changed when centos seperated the two projects. Now I can't get it to work. This is what I am trying to use but it says "nothing to do". updates = rsync://ftp.linux.ncsu.edu/centos/$release/$repo/$arch/RPMS/ This with gatech on the other hand works but they have a 20 connection limit so I would like to get ncsu.esu working again.

Hi Folks, Given k RVs with MVN distribution N(mu,S) (S a kxk covariance matrix), let (w.l.o.g.) X1 denote the first r of them, and X2 the last (k-r). Likewise, let mu1 and mu2 denote their respective expectations. Then, of course, the expectation of X2 given X1=x1 is mu2 + S21*inv(S22)*(x1 - mu1) and the covariance matrix of X2 given X1=x2 is S22 - S21*inv(X11)*S12 where Sij is the

Out of necessity, a friend of mine and I have created a patch for syslinux to allow it to modify the mbr and partition table in windows. It adds a -m option to syslinux. If given, it will overwrite the MBR of the drive specified with the mbr.bin provided in syslinux, and if the bootable flag is not set on the partition being syslinuxed, it will set it. This was done to distribute with my USB

Dear kind R-experts. Does anybody have an experience to use optim function? If yes, what is the main difference between two method "BFGS" vs "L-BFGS-B"? I used "BFGS" method and got what I wanted. But when I used "L-BFGS-B" the error message said that "L-BFGS-B needs finite values of fn". So that means "BFGS" method can handle even if fn

Hi, R-help, I have a group of data from RNA-seq want to be analyzed by Fisher's exact test in R. I want to compare the significant difference of about 30,0000 individuals in two different samples, and I have no idea how to use R, so could you please give me some suggestions or the scripts for Fisher's exact test? Thank you very much. Best, Guanfeng Wang [[alternative HTML version

I want to delete a row from a data frame XYZ where A == "TRUE". Let's assume there are five variables in this data frame XYZ. My deletion is based on the TRUE vs. FALSE value under variable A. How do I do this? Thanks! My current code: for (i in 1:length(XYZ$A)) if (XYZ$A == "FALSE") XYZ<-XYZ else XYZ<- XYZ[-i,] Error message is: Error in if (XYZ$A ==
