Hello, for testing & learning purposes I create X11 device and specify layout like layout(c(1,2,3), 3, 1), so I could play with parameters and see several plots at the same time. That works fine until I try to create 4-th plot - all other plots erased. Such behaviour isn't desirable for testing purposes and I'm asking where to look to disable erasing other plots. Regards, Oleg

Hello, is't possible to specify pattern in levels ? > y=c("ff","f","m","mm","fm","mf","ffm","mmf","mmm","fff"); > factor(y) [1] ff f m mm fm mf ffm mmf mmm fff Levels: f ff fff ffm fm m mf mm mmf mmm I want to specify levels using regexp ("f.*","m.*") or use

I just upgraded R to version 2.4.0 and now I can't install packages RdbiPgSQL. I used the same procedure I did for previous versions of R ! Actually, last time I installed RdbiPgSQL day before upgrading but now I got: downloaded 27Kb * Installing *source* package 'RdbiPgSQL' ... creating cache ./config.cache checking for PQconnectdb in -lpq... no I could not find your PostgreSQL

Hello, I've been trying to set up dovecot to support passwd-file + passwd/PAM auth. I made an unusual config (passwd-file as userdb failed to work for me), which uses static as userdb: =============== passdb { driver = passwd-file args = username_format=%u scheme=CRYPT /etc/dovecot/users } userdb { driver = static default_fields = uid=vmail gid=vmail home=/var/spool/mail/%d/%n }

Hi, I have been using myisam tables in mysql with rails because my client will soon want fulltext searchable content, however when I migrated my development db from schema.rb all of the tables generated were innodb. I understand that I can override this, but also like the transactions and foreign keys of innodb. So 2 questions really: 1. are transactions in activerecord dependent on innodb or do

Dear all, I have gridded data at 5' (minutes) resolution, which I intend to coarsen to 0.5 degrees. How would I go about doing this in R? I've had a search online and haven't found anything obvious, so any help would be gratefully received. I'm assuming that there will be several 'coarsening' techniques available - I'm after something fairly simple, which for example,

Hello, I created a simple histogram with: myHist<-hist(myData) the object myHist now has two arrays (among the others): myHist$mids myHist$counts Since myHist$counts contains some "0", and I want to calculate the linear fit among myHist$mids and log(myHist$counts), I want remove the elements of both arrays where these "0" occurs. which are the possible solutions to

Hi, I have a FreeNAS server with a cifs share, accessible by all the lan users (guest access) Every one can access it and write in it. When Mac OSX users are creating a file or a folder, they write it with the following permissions : rwxr-xr-x Rhis only happen with mac users. So the other users can't modify or delete theses files/folders. How to configure my share if I want that all the

R-helpers: I have a dataset that has 168 subjects and 12 variables. Some of the variables have missing data and I want to use the multiple imputation capabilities of the "mice" package to address the missing data. Given that mice only supports linear models and generalized linear models (via the lm.mids and glm.mids functions) and that I need to fit Cox models, I followed the previous

Hello I would like to pass a model formula as an argument to the with.mids function from the mice package. The with.mids functon fits models to multiply imputed data sets. Here's a simple example library(mice) #Create multiple imputations on the nhanes data contained in the mice package. imp <- mice(nahnes) #Fitting a linear model with each imputed data set the regular way works

Using R-2.12.1 and latticeExtra-0.6-14, I would like to understand why a rootogram displaying samples from the Poisson distribution looks like I expected it, whereas a rootogram using the normal distribution does not: library(latticeExtra) rootogram(~rpois(1000, lambda = 50), dfun = function(x) dpois(x, lambda = 50)) rootogram(~rnorm(1000), dfun = function(x) dnorm(x,mean(x),sd(x))) I

Hello folks, I am a relatively new user of R and created multiply imputed data sets with the 'mice' library. This library provides two functions for complete-data analysis on multiply imputed data set objects (lm.mids and glm.mids). I am trying to estimate a series of Cox PH regression models and cannot figure out the best way to do this. Is it possible with the mitools library?

I am looking for a function (or package) to plot histograms of directional data such as wind direction. I believe these are called rose diagrams. Is there an R script for this? If not, can it be constructed in a function calling primitive graphic calls (lines, circles, boxes or polygons)? The stars function is not quite right. -- David Finlayson Geomorphogist and GIS Specialist NearPRISM -

Hi, I have a casting/formatting question on hist.POSIXt: The histogram plot from POSIXct works perfect (with help of Prof. Ripley -thanks!). When processing the hist(plot=FALSE) output and then plotting the results over the x-axis (bins) coming from hist(), I lose the date/time labels, getting instead integers displayed. Trying to cast the $breaks with as.POSIXct gives silly results with

Hi, I need this plot: given: x,y - numerical vectors of length N plot xi vs mean(yj such that |xj - xi|<epsilon) (running mean?) alternatively, discretize X as if for histogram plotting and plot mean y over the center of the histogram group. is there a simple way? thanks! -- Sam Steingold (http://sds.podval.org/) on CentOS release 5.6 (Final) X 11.0.60900031 http://thereligionofpeace.com
