Hi, I would like to ask how the paste(S1, S2, sep="") function internally works. Are the two stings copied to a new String? I have a program where successively strings are build up. First the program calls an external function and depending on the result it builds up strings to visualize the result. The external function is really fast, also for huge input data. But the

Hello, I have stings which have all sort of characters (numbers, letters, punctuation marks, etc) I would like to stay only with the numbers in them, does somebody know how to do this? Thank you Felipe Parra [[alternative HTML version deleted]]

To whom it may concern, I am very interested in embedding the R functionality in our application. This is a C application that currently runs on Win32, but will also run on Linux in the future. From the material that I have seen, I need R compiled as a shared library to evaluate R expressions from C. Is this correct? If so, can I download this shared library from somewhere? Is there any API

I've pulled this down with Firefox, wget, a bittorrent client and an ftp client using Windows as well as Linux hosts. Is something wrong with the distributed DVD image? It has failed an MD5 check every time I've pulled it down.

Hi, I want to offer a CSV download of data in my Rails app (eg. An "Export to Excel" link to grab the current view of tabulated data). However, I can''t seem to break-out of the Rails framework to output this non-HTML data. Even if I eliminate my layout template from my view, the most basic view (no HTML) will still wrap the output in

Hi, I am in the process of linking a C/C++ application to the R.dll directly. I have obtained the R source code and compiled it successfully. I have also successfully linked the R.dll directly into our application and have made calls successfully into the R.dll that are included in the sample rtest.c and in the "Writing R Extensions - The R API". The R functionality that we are

After loading the RODBC package version 1.1-7, Ctrl-C changes its behaviour and is quitting R and returning to the (unix-)command prompt on the solaris2.8 platform here.

Hi everybody, my goal is to display symbols on the x-axis of a barplot. I read some mathematics strings in a file and convert them to an expression as follows: tt<- scan(file = fstr ,'what' ='character', sep = ""); for (iaa in 1:length(tt)) { tt[iaa]<-do.call(expression, lapply(tt[iaa], as.name)); } I obtained the following result: tt =

Is there a list anywhere of the DTrace FBT provider calls for each version of Solaris since the Nevada build that hosed the DTrace Toolkit. I have no issue with rewriting what I need, but I am hoping to stave off having to look at all the source code to find everything. I know there is a new provider under development, but I need to be able to program DTrace routines for all the updates in

Hi, I really need help with making the ''searches_on :all'' in Duane Johnson''s TextSearch work with MySQL (not sure if it works with other db''s). http://wiki.rubyonrails.com/rails/pages/TextSearch I realize that there are other search packages out there. But this particular solution best fits my small needs of searching a small database. I''ve gotten

The current documentation of ?on.exit reads [1] > `on.exit` records [`expr`] as needing to be executed when the current function exits... This is almost always how it is used, however I don't see that as explaining this other common way to use on.exit(): local({ old = setwd(...) on.exit(setwd(old)) readLines(...) }) There's not really a "function" here. It may be

Dear friends - windows R 3.3.3 - sorry to ask a simple question - but I cannot make setwd work properly in scripts In the example below I have made a directory in C (firstdir) and a directory in that (secdir) and the intention is to change directory to the second from the first - it works when I put the entire path but not the tilde - what am I missing? I was around rwf 2.14 as per the help

Hi, I want to know if my idea is possible within the rails framework. I want to write a rails app that uses the same code to manage two classes of widgets; "wired widgets" and "wireless widgets". For the most part, all the code to manage these two classes of widgets will be identical. The only differing part are some of the underlying field names in each respective db table

Hello I think there is a conflict between setwd() and \SweaveOpts{prefix.string=}. In the same document, those both command get Sweave confuse the files and directories. See: say my .Rnw document is in File1 If one inserts some setwd() for another file: -setwd(File2) then the command \SweaveOpts{prefix.string=graphics/Rplots} will search the "graphics" folder in File2 because of

Dear List A 2-dimensional array seems to be "interpreted" as a matrix whereas higher dimensional arrays are interpreted as arrays, e.g. > a1 <- array(1:8,c(2,2,2)) > class(a1) [1] "array" > a2 <- array(1:4,c(2,2)) > class(a2) [1] "matrix" If I write a generic function (apologies if this is the wrong word) on arrays as foo <- function(x)

I have a SCSI tape backup unit attached to a kvm host managed by libvirt. Is there a way to expose the SCSI device in libvirt so I could pass the device to a virtual machine and have the virtual machine control the tape backup? Defining the device as a SCSI disk does not appear to work. In this situation, live migration is not an issue. The VM would always be tied to this host.
