I have data from several sensors that recorded data at hourly intervals during seven months. I want to separate daily variation from the trend, and also be able to zoom in on only one month of data. I have not been able what functions to use, I can not figure out from the help for 'ts' how to use hourly data. I guess this is routine-work for a lot of people so I hope someone can

Dear R-gurus, I would like to zoom in a plot, e.g. I select a region on the x-axis and then I would like the ranges on the y-axis to change accordingly. Is it possible to do this with existing functions, or do I have to invent some data selection before plotting? See below a short example, where I select ylim with trial and error, which I want to avoid. Cheers, Henrik Andersson

I have been using R for a few months to plot my data, and fit statistical models and so on. It is stated that R is not only a package for statistcs and graphics but also a programming language. Currently I am working with Fortran 90 to do numerical simulations (1D reactive -transport), and subsequently visualize it in some external software (spreadsheet). As I now started using R I will plot my

I really like to use R for all my graphs, and as I work with stable isotopes I want to have a proper chemical notation in my plots I have looked at ?plotmath, but didn't find the answer and also searched the R website. ------------------------------------------------------------------------ -- plot(1:10,xlab=expression(^{14}*C)) # I want to have a superscript with nothing in front, but it

I want to create a character vector based on the table (shortened for display) below: Where there are ones in the matrix I want the column name to appear and where there are zeros nothing, which would make the vector in this shortened case: combinations <- ("A B","A C","A E H","A F G","B C D","E G H",A C D E H","A C D F

I apologize in advance for posting a question not related to R. I need references to papers that use multiple linear regression in an industrial application and also in a biological experiment. This is aimed to biologists/chemists (non-statisticans) so if anyone has written a brilliant paper where the use of multiple regression is important and also understandable to people with little

Hello fellow R people, I can not figure out a pretty way to use strplit with vectors Imagine that I got the following data from someone with ID's representing several factors ID data A1-B1-t1 0 A1-B1-t2 1 A1-B2-t1 5 A1-B2-t2 10 A1-B10-t1 0 A1-B10-t2 1 A1-B20-t1 5 A1-B20-t2 10 ... I would like to turn this dataframe to station substation time data A1 B1 t1 0 A1 B1 t2 1 A1 B2 t1 5

Just a small suggestion since Windows have a file system not designed for command line use... Would it be possible to add the possibility of automatically adding/modifying the path to the R executables in the windows installer program? --------------------------------------------- Henrik Andersson Netherlands Institute of Ecology - Centre for Estuarine and Marine Ecology P.O.

Hi all, I have tried to create a DocumentTermMatrix with a tm package, but i get this error : Error in tolower(txt) : invalid input 'PROD Z LAHKO GNETNO MELJNO GLINO, ... in 'utf8towcs' I tried doing this as it is showed in : http://www.r-project.org/doc/Rnews/Rnews_2008-2.pdf (An Introduction to Text Mining), with this R code :

Hello, I am trying to upgrade dovecot from 1.0.7 (the dovecot verison in base repo) to 1.2. The installation of .rpm got from atrpms.net aborted with a dependency error : error: Failed dependencies: libpq.so.5()(64bit) is needed by dovecot-1.2.16-1_114.el5.x86_64 This is strange because the libraries are there : yum list libpq* Installed Packages libpqxx.x86_64 2.6.9-3.el5.rf installed

OK! I'm sorry about this. As I wrote earlier I'm totally lost... but I will try to explain the problem in steps bellow, ok. 1. I installed the rpm's for samba, Version 2.0.2a-ssl I think this is the version distributed with redhat linux 7.0 2. Then I changed the parameters in the /etc/samba/smb.conf file, and in this file I added the folowing parameters. [global] netbios name

The diagnostis.txt file don't seem to solve this problem. Now my samba server is now available for browsing, I dont know how I should solve this actually I'm totally lost I even tried to erase the rpm file and compiled a source file.

I am about to write general functions to read the output of simulations models. These model generate output files with different sections which I want to analyze plot etc. Since this will be used many people at the department I wanted to make sure that will do this in the best way. For instance I want to read a snippets of data from a text that look like this.

Do I have the right impression that it's currently not possible to produce confidence intervals for the nls predictions using R? I had a course were we used SAS PROC nlin and there you could get intervals for the parameters and the prediction but I do not have access to SAS. Would it be difficult to implement, I tried to dig into the help pages of nls, vcov and nlsModel but I could not

I would like to display output to a tcltk window from e.g. a call to summary().

Dear all, I have come across some Windows Script code which calls the "file.exists" function in R to check for the existence of a particular file on an R server. This is what the code looks like: do { // some useful code } while (m_workspace.session.eval("file.exists(" + dataFile +

Dear all, I clicked "File-New Script" to open a R Editor, typed some commands in it and then saved it to a file.
