similar to: Call C code from R

Hello, All! I'm new for R-devel list. And I'd like to ask some questions, maybe they will be stuped for the most part of members of the list. I need to call function which is written in C++ from R. My questions are: 1. How should I include libraries (for example, iomanip, sstream, iostream)? 2. Can I use namespace? Thanks All :) Olga

Hi all, I have a problem but i am not sure that this is the right mailing list. I'm writing a R program which call a C++ program, through the function .Call. I use to compile the c++ script with the command R CMD SHLIB SpTempWrapC.cpp -Wall -l covmodel.h -l util.h Everything works fine since, for mistake, i paste in the terminal the content of the r-script. Now, when i try to compile,

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.

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.

Hi all, after seeing a near inifinite stream of "Checking instruction ''" from bugpoint, I thought to improve that a bit. Turns out that bugpoint outputs the name, which is often empty (especially for the big bitcodes you want to pull through bugpoint :-). Below patch changes the behaviour to output the assembly version of the instruction instead of the name, which makes things

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

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

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, I have recently tried installing Java on Centos 6.4 and have found that the wiki tutorial for this subject is quite outdated (the proposed method doesn't work on the new version as the spec file is outdated and there is no need to rebuild the rpm with nosrc file anymore). I would like to post a tutorial on installing Java on Centos that would be more up-to-date and referring to the

Hi, I am a brand new user and may be my question is too simple. I have R on our (not Unix) server. I am trying to build a decision tree and the error message says "couldn't find function rpart". Does it mean I have to ask our server guy to install an additional package? Thank you, Olga [[alternative HTML version deleted]]
