Hello, I wrote a package, which in the NAMESPACE file exports functions like this: exportPattern("^\\rh") On R-2.8 (Linux, 64), upon loading the package I have the rh functions present. On R-2.10, Mac OS X, (32 bit), it builds, loads, but the functions are not loaded, i.e the only function is rhyper (which is not from my package). Is there something wrong with my package setup?

library(some_library_name) Suppose I load a library. I'm wondering what command I should use to list all the functions, classes and variables defined in the library.

Dear R-users, I'd like to perform arithmetic functions on 1000 files containing a 2000x2000 matrix. Can anyone advise? For example, File1 File2 Output 1 1 1 4 4 4 5 5 5 2 2 2 + 5 5 5 = 7 7 7 3 3 3 6 6 6 9 9 9 Muhammad -- Muhammad Rahiz | Doctoral Student in Regional Climate Modeling Climate Research

Hi, I am looking for a R package which is capable to process and analysis pictures of tissues (stained) in an automatic way. I had a look on biops and EBImage (Bioconductor) but they are not automatic... Did you already use/know a such package ?

Hi, I need to check if a string "<rh>a,b,c,d<rh>" is delimited by two "<rh>" 's as efficiently as possible(I need to do this a lot of times) and return TRUE. Can someone suggest a good technique? [[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

Hello, I get a value which stores a relative file name. (I get it from another function, which I don't want to change.) e.g. > fileName <- "../data/2010-08.csv"; Is it possible to get the absolute file path out of this value? (e.g. /home/sebastian/documents/data/2010-08.csv) Kind regards, Sebastian
