Hi, I'm trying to install Sciviews-K on Linux Ubuntu 9.10 (karmic) but I'm not able to establish the connection between Komodo and R. Here;s the error I get, plus some diagnostic info: R version 2.9.2 (2009-08-24) R is SciViews ready! Error in get(name, envir = asNamespace(pkg), inherits = FALSE) :   object 'httpdPort' not found > ls() [1] "svStart" > Sys.info()

Is there a way to identify (for subsequent replacement) which rows in a matrix are comprised entirely of *integers*? I have a large set of *nx3 *matrices where each row either consists of a set of 3 integers or a set of 3 real numbers. A given matrix might looks something like this: [ ,1] [ ,2] [ ,3] [1, ] 121.0000 -98.0000 276.0000 [2,

Is there a c++ equivalent switch statement in R? -- Rajesh.J [[alternative HTML version deleted]]

Stupid question, but its been a long night. If I have a long vector how can I turn it into a list of the same length x<-rep(seq(1,100,by=1),each=10) [[alternative HTML version deleted]]

I am trying to get documentation about the random number generator used in "sample". The help for sample does not mention it. Can anyone point me in the right direction. Thanks [[alternative HTML version deleted]]

REXP has an asBytes() method. Will this capture the output of an R plot function if a proper graphics device is used? It appears R insists on sending plot output to a file. Kind of strange since it insists on loading all your data into memory before it can do anything. If so then does anyone know what this would be? I prefer png or jpeg. Example: c is an RConnection REXP r =

Hi folks, Maybe that is not the best place to ask, but I 'd like some of you could help me... I'm using jri to run R commands under Java, by its examples I can eval expressions, returning single values or vectors to my Java variables. But, I would like to know how to assign the values of a Java vector (like: double x[] = {1.7 , 2.8 , 3.4}; ) to a R variable, so I can eval a function

Good afternoon everybody, I'm writing a little function to visualise hypothesis testing. Therefore I need to extract the confidence level of a t-test. Here a little example: x <- str(t.test(1:10) gives List of 9 $ statistic : Named num 5.74 ..- attr(*, "names")= chr "t" $ parameter : Named num 9 ..- attr(*, "names")= chr

Dear list, I wish to use a specific driver to process an sweave document in the inst/doc directory of a package. Specifically, I would like to use either cacheSweave or pgfSweave to speed up the creation of the vignette which requires lengthy computations. The same request would also apply to the highlight driver, to provide syntax highlighting of R chunks. In "writing R extensions" I
