Dear all, I am using gnome-terminal to run R, and I noticed that standard PageUp/Down do not work but they do work for other programs within the same terminal window (e.g. irssi). Scroll bar does not work either. I run R using GNU-screen, but it doesn't seem to make any difference. Many thanks Olga ------------------ R version 2.11.1 (2010-05-31) 2010 x86_64 GNU/Linux Ubuntu 10.04.1 LTS

Dear all, mydata<-data.frame(x1=c(1,4,6),x2=c(3,1,2),x3=c(2,1,3)) cor(mydata) x1 x2 x3 x1 1.0000000 -0.5960396 0.3973597 x2 -0.5960396 1.0000000 0.5000000 x3 0.3973597 0.5000000 1.0000000 I wonder if it is possible to fill only lower triangle of this correlation matrix? Using 'dist' doesn't seem to be useful as it doesnt allow to convert this table

Dear all, I am making a barplot as following: barplot(c(1,2,3,5,2,3,1),names.arg=c("100","200","300","400","500","600","700"),xlab="diameter",ylab="flow",main="some title",space=0.1) I am also trying to add a probability density curve, however using lines(density(c(1,2,3,5,2,3,1))) does not give

Dear all, I am trying to import data with read.csv and my file is on remote machine. I believe that I need to open a connection, not sure about syntax though. I would appreciate any suggestions, Thanks! Olga

Dear all, I am using GNU screen to run multiple R sessions from one working directory in order to split task, however I noticed that dataset is not synchronized e.g. if I have two sessions R1 and R2, and I remove an object from R1, R2 doesn't change as expected or change at random. I have tried to save.image(), q() and then restart both sessions, but it does not help. Any suggestions?

Dear all, I have a dataframe: df<-dataframe(a=c(1,2,3),b=c(4,5,6),c=c(7,8,9),d=c(10,11,12)) I want to obtain a new dataframe with columns a and b being standardized ((x-mean(x))/sd(x)); the other two columns (c,d) I want to leave unchanged. What is the best way to achieve this? I have been trying to use subscripts but did not succeed so far. Any tips? Many thanks, Olga

Hi, I am Olga Viedma. I am running a Zero-inflated negative binomial (ZINB) multi-level model using MCMCglmm package. I have a doubt. Can I use the "Liab" outputs as fitted data, instead of the predicted values from "predict"? The liab outputs fit very well with the observed data, whereas the predicted values are so bad. Thanks in advance, Olga Viedma D . Olga

brtfs could be supported on Opensolaris, too. IMO it could even complement ZFS and spawn some concurrent development between both. ZFS is too high end and works very poorly with less than 2GB while brtfs reportedly works well with 128MB on ARM.

Hello, All! I have function which is written in C, the function uses other functions also builded bu me. Now I need to use the function to build R function. My questions are: 1. How can I include libraries (for example, iomanip, sstream, tcl.h)? 2. Should I put other function to the separate file and then include the file? Thanks All :) Olga [[alternative HTML version deleted]]

My decision tree grows only with one split and based on what I see in E-Miner it should split on more variables. How can I adjust splitting criteria in R? Also is there way to indicate that some variables are binary, like variable Info_G is binary so in the results would be nice to see "2) Info_G=0" instead of "2) Info_G<0.5". Thank you in advance! And thanks for Eric who

Hello: I could use help understanding an error reported by "R CMD build sos" that's new with R 3.3.0: Error in texi2dvi(file = file, pdf = TRUE, clean = clean, quiet = quiet, : Running 'texi2dvi' on 'sos.tex' failed.

Hello: Changes in R seem to have broken the sos vignette, and I don't know how to fix it. The build on R-forge, "https://r-forge.r-project.org/R/?group_id=235&log=build_src&pkg=sos&flavor=patched", ends as follows: Error in texi2dvi(file = file, pdf = TRUE, clean = clean, quiet = quiet, : Running 'texi2dvi' on 'sos.tex' failed.

I am using "plot" and "text" commands to display the decision tree I built, here is the code: plot(fit, compress=TRUE) text(fit, use.n=TRUE) but the the result of this code is not readable. Text doesn't get fully displayed (missing on the margines and overlapping in the middle). Where can I get info on how to adjust the tree display and text size display? Please help.

Hello, All: The vignette with the sos package used "upquote.sty", required for R Journal when it was published in 2009. Current CRAN policy disallows "upquote.sty", and I've so far not found a way to pass "R CMD check" with sos without upquote.sty. I changed sos.Rnw per an email exchange with Prof. Ripley without solving the problem; see below. The

I stumbled across this issue because I requested to install the sysreport package in my kickstart file. Anaconda complains that such a package doesn't exist. There is a bug report about this already (http://bugs.centos.org/view.php?id=2492), but it's certainly a strange situation. 1. Anaconda doesn't think the package sysreport exists 2. yum thinks it exists:

Hello, All: I have for years copied an address like "C:\Program Files\R\R-2.15.0\library\MASS\scripts" from Windows Explorer into R, then manually replaced "\" with "/". I have a function to automate this added to the development version of "sos". However, it generates a warning in "R CMD check" ("parse error: unexpected
