Hi Martin, It is really a 'PATH' problem. After adding C:\Program Files\Graphviz2.20\bin to the 'PATH' environment variable, the Rgraphviz package can be loaded without any error messages. Sorry that I ONLY set my 'PATH' environment variable correctly for R but not for Graphviz. Thank you and Duncan so much for your great help. Howard On Tue Mar 30 18:12:54

Dear guRus, I'd like to learn how to make a function recognize the name of an object/vector given as argument If I have : testFun <- function(x,y) plot(x,y, main=paste("plot of",names(x),"and",names(y)) ) # this just a simple example ... a1 <- 5:8 b1 <- 9:6 testFun(a1,b1) # Returns the plot, but not the names of the objects/vectors given as arguments, # but

Dear list, I have encountered a special case for searching a linear regression where I'm not satisfied with the results obtained using the traditional least squares method (sometimes called OLS) for estimating/optimizing the residues to the regression line (see code below). Basically, a group of my x-y data are a bit off the diagonal line (in my case the diagonal represents the ideal or

Dear List, we're trying to install R on Solaris10 on a x86 (amd64). During the installation we pass successfully the ./configure but we get an error through the built-in function "_isnan" which we see existing in /lib When passing the command "make" we get : gcc -std=gnu99 -I../../src/extra/zlib -I../../src/extra/bzip2 -I../../src/extra/pcre -I. -I../../src/include

Dear list, ?require says : "... |require| is designed for use inside other functions; it returns |FALSE| and gives a warning (rather than an error as |library()| does by default) if the package does not exist ..." However when I run the following code I don't get any TRUE / FALSE statements (but the warning only). Since I want to test from inside of a function if a given package

Dear list, I'm wondering how to optimize functions/processes like the one shown below (which simplifies something we're trying to do with very large datasets). In many cases I've noticed that using apply, sapply etc can help speeding up processes, but in this case I don't see how I could do so. a <- runif(10000000,0.5,1.6) C <- 2 M <- 10000000 system.time( for (i in

Dear r-helpers, Can anyone suggest a remedy to the following failure of Rgraphviz to load? > library(Rgraphviz) Loading required package: graph Loading required package: Ruuid Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/Library/Frameworks/R.framework/ Resources/library/Rgraphviz/libs/ppc/Rgraphviz.so':

Dear list, I?m using R embedded in another program (coded in tcl/tk) under Windows Vista. In this context I don?t launch Rgui.exe but rather Rtem.exe. Now I have a problem finding libraries not specifically installed as administrator (and which are not in the path ?program files? but in Contacts\Documents of the current user). To be precise, the user launching my tcl/tk program can?t find

Hi Gabor, I just used your R code below and the code worked properly without any error messages. Attached is the output graph, which may be the one you expected. library("Rgraphviz") set.seed(123) V <- letters[1:10] M <- 1:4 g1 <- randomGraph(V, M, 0.2) g1 plot(g1) Thanks.

Hi All, I tried to install the package of Rgraphviz in the following two ways successfully: source("http://bioconductor.org/biocLite.R") biocLite("Rgraphviz") install.packages(pkgs="C:/Progra~1/R/lib_download/Rgraphviz_1.24.0.zip", lib="C:/Progra~1/R/R-2.10.1/library", repos=NULL) but when I loaded the package though library(Rgraphviz) or

Dear list, I just realized that one of the examples given in the help page to the function makeCluster of the library(snow) has a small syntax error : ## to get started library(snow) ?makeCluster .. will open a halp page containing the command towards the end of the examples : cl <- makeCluster(c(rep(list(macOptions), 2), rep(list(lnxOptions), 2), rep(list(winOptions),

Dear guRus, I'm maintaining central R installation (Linux) for our institute. The startup screen of R traditionally echoes some messages (starting with "R version ...Copyright (C).. The R Foundation for Statistical Computing...") and I'd like to display for example right after these messages some other messages about our specific setup, how to contact me etc ... What

Dear List, when reading MS Excel files in R using package RODBC I encountered the problem of having the first line of data getting omitted. I read the data as : > library(RODBC) > channel1 <- odbcConnectExcel("myFile.xls") > sheet1 <- sqlQuery(channel1, "SELECT * FROM [Cell measures (1)$]") # I use sqlQuery() instead of sqlFetch() since the sheet I

Dear list, when running a mood.test() (part of package "stats") on slightly longer vectors (than the example from the help-page) we get the error-message shown below : once both vectors tested are of length 50 this error oocurs. Note, that this problem didn't occur with R-2.7.x (or even older versions). > x <- rnorm(50,10,5) > y <- rnorm(50,2,5) > >
