I have written a function to plot data which will be used for various different chemistries. A simplified version is: plot_data <- function(risk,levels,chem,sd2,measure){ plot(risk, levels,main=paste ("per", sd2, measure, "\n in usual", chem)) } The problem is with the title. This works fine if the variable "chem" is just text, but if it is an expression then

Hi, Has any one know how to skip ix86 packages from installation in Centos kickstart? Most of our machines have 64bit Intel/AMD CPUs, and it make non-sense to still keep 32bit compatibility. Even worse of i*86 packages is, when upgrade we have to recompile both ix86 version and x86_64 version to get an automatic yum upgrade. I know we could use 'exclude' option to exclude i*86 packages

Hi all, Sorry if this seems too basic. But is there a way to overwrite the target of a symbolic link without first deleting the symlink itself? For example, if I have this: public_html -> releases/b2b-20080228 ... and there's a new update, I can then just do the following: $ ln releases/site-latest public_html I tried using the -f option but it doesn't seem to work as expected.

Hello, my enviroment: All Servers are Ubuntun 16.04-18.04 SAMBA AD DC Server and several SAMABA DOMAIN MEMBER (connected via WINBIND). In ADDC I've created a group "restrictaccess" and added some users. Now when im typing "id <username>" on a Domain Member, for some users the group "restrictaccess" are listed for some not! For example: ON DC: #

Hi all, I don't see xorg-x11-libs-6.8.2-1.EL.13.37.7.i386.rpm in the CentOS4 x86_64 updates repo. It is listed in the security announcement: http://lists.centos.org/pipermail/centos-announce/2007-April/013658.html I see the 4 other i386 packages there: devel, deprecated-libs, Mesa-libGL, and Mesa-libGLU. Just the libs package is missing. -- Garrick Staples, GNU/Linux HPCC SysAdmin

Hello, I’m reaching out because our online radio station (sites.up.edu/kdup/) has stopped streaming in the last week - the website itself works fine but when anyone attempts to listen to the live music stream they receive a message that says “cannot connect to the server “icecast.up.edu.” Do we need to update the server, or is this a problem that someone else can take care of? Let me know if I

rsync does not sync the timestamp on symlink (Solaris 8). It is probablly due to the limitation of Unix implementation of symlink, but I would like to know why rsync/Unix does not do this, and what we can do about it. Is the conclusion that "rsync syncs everything except the timestamp on symlink"? Why do I need timestamp on symlink? Supposed something stopped working because something

Hi, please can you help me. When I add a legend to a boxplot it appears inside the plot area, how do you get it into the margins? I have already changed the parameters so there is space for it on the margin on the right hand side of the graph. Thanks, Emily [[alternative HTML version deleted]]

I'm trying to figure out if it's possible to use a character string as an equation, e.g: eqn1string <- "x^2 + x + 5" Then I want to tell R: 1) that eqn1string is actually an equation (even though it was stored as a character string), and 2) to apply the equation to a specified value of x (e.g. given x <- 6, what is the result of the equation). Thanks in advance for any

Hello List, ? I have a dataset consisting of strings that I want to split while saving the delimiter. ? Some example data: ?leucocyten + gramnegatieve staven +++ grampositieve staven ++? ?leucocyten ? grampositieve coccen +? ? I want to split the strings such that I get the following result: c(?leucocyten +?, ??gramnegatieve staven +++?, ??grampositieve staven ++?) c(?leucocyten ??, ?grampositieve

Good day, I need to subset a data by removing several rows. I know the %in% operator, i.e. sub <- mydata[group %in% c("A","B","E","G"), ] What I need is the opposite, that is remove rows and/or columns. What is the operator for "NOT IN"? I tried (i)! %in% and (ii) ^%in% and both resulted in a "could not find function" error.

I thought replacing the spaces following instances of +++,++,+,- with "\n" and then reading with scan should succeed. Like Ivan Krylov I was fairly sure that you meant the minus sign to be "-" rather than "?", but perhaps your were using MS Word as an editor which is inconsistent with effective use of R. If so, learn to use a proper programming editor, and in any case

Dear friends: Just installed Centos 5. Very impressed but as a newbie I am a bit confused about the the role of the Software Updater vs. Add/Remove and Yum(ex). Which one do I use to update the installed programs, please? Thank you. Benjamin -- Sher's Russian Web http://www.websher.net Benjamin Sher sher07 at mindspring.com

I have a data frame with three columns, one coded as a factor. I would like to separate my data out into separate data frames according to the factor level. Below is a simple example to illustrate. I can get R to return the data in the correct format but cannot work out how to get separate data frames. I am a newcommer to programming in R so am not sure what I am missing! Thanks, Emily

Hi, I'm new to R and I have a file with many rows of values. Each row contains a title and values for a contingency table e.g. row 1= title 8 0 37796 47 which is a table called 'title' with values 8 0 37796 47 I would like to know how I can import this using R and for each row calculate a p value using the fisher test. Using each p value I will do multiple a correction. I am

Dear all, I have many csv files whose contents I want to change a bit en masse. So far, I've written code that can change them in a for loop, like so: # Subset of files in the folder I want to change subset = "somestring" # Retrieve list of files to change filelist=list.files() filelist = filelist[grep(subset, filelist)] for(i in 1:length(filelist)){ setwd(readdir)

Hi Dr. Snow, I am a graduate student working on analyzing data for my thesis and came across your post on an R forum: The default link function for the glm poisson family is a log link, which means that it is fitting the model: log(mu) ~ b0 + b1 * x But the data that you generate is based on a linear link. Therefore your glm analysis does not match with how the data was generated
