Hi all, is there a way to properly terminate Rserve instead of killing the process? I run Rserve in a linux box that serves my Java client.. I have a cronjob that runs Rserve every morning. However, I'm killing it at night manually for the moment. Is there a way, given host/port, I can run an R command to properly terminate it?? Thanks a lot in advance!! - yoooooooo -- View this message in

Let's say i have a = c(1, 4, 5) b = c(2, 6, 7) and i have matrix m, what's an efficient way of access m[1, 2], m[4, 6], m[5, 7] like of course m[a, b] = is not going to do, but what's an expression that will allow me to have that list?

Hello, I'm not sure how to go about this. Suppose I have a function SEXP boo(SEXP x){ //do something } Also, I have an executable which embeds R in itself. I would like to provide a R function to user code to call that calls 'boo' e.g ##user supplied expression that is given to me x<-1 boo(x) One way is to create a library with function boo that performs .Call to boo, but is

Thank You David and Mats for the reply, The reason I need to know that main is the entry point is as follows : I have a dead code elimination pass that removes the function call for boo. boo was initially called from the main function , but since the return in the main function has no dependency on boo, boo function call is removed. Now I want to remove the function definition of the functions

Hi all, I have this list of strings [1] "1 ,2 ,3" "4 ,5 ,6" Is there an efficient way to convert it to data.frame: V1 V2 V3 1 1 2 3 2 4 5 6 Like I can use strsplit to get to a list of split strings.. and then use say a = strsplit(mylist, ",") data.frame(V1 = lapply(a, function(x){x[1]}), V2 = lapply(a, function(x){x[2]}),.....) but i'm

Hi all, let's say I have matrix People Desc Value Mary Height 50 Mary Weight 100 Fanny Height 60 Fanny Height 200 Is there a quick way to form the following matrix?

Does anybody know how to negate a string in a grep command, i.e., what I need is to return only strings that do NOT contain a second string anywhere in the entire string. for txt <- c("boo","goo","doob","foo","boofoo") I need a grep command that returns strings with "oo" except when "b" is present anywhere. I know that

Hi, let's say I have this A = matrix(c(1, 2, 4), nrow=1) colnames(A)=c("YOO1", "YOO2", "YOO3") # ie # YOO1 YOO2 YOO3 #[1,] 1 2 4 HELLO <- NULL HELLO$YOO1="BOO" HELLO$YOO2="BOO" HELLO$YOO3="HOO" and I want a matrix that will sum my categorization.. how can I do it efficiently without any loop? #ie BOO HOO

I''m trying to test that "static" pages (they''re ERB, but get cached), generated through rails, don''t render any stray flash notices left over by the authentication system (Devise) or wherever else. I''ve tried writing this controller spec, but it appears that response.body only renders the template, not its layouts? describe "so that static

First, if I have an S4 class boo should I define S3 method for printing print.boo(..) or should I define S4 method print(..). I mainly need to define print function only because some user might call it and then I would like to dispatch the call to right function instead. Second, it seems that by defining S4 generic function print, it is possible to break argument hinting on the status bar.

R 2.7.2 Windows XP I am using apply to compute a series of Student's t-test from two matrices, sample1 and sample2. boo<-apply(sample1,1,t.test,sample2) I want to pick of the p-values from the tests, but can't seem to get it to work. I have tried several methods to get the values including: boo<-apply(sample1,1,t.test$t.test,sample2) boo<-apply(sample1,1,t.test,sample2)$t.test

I''ve tryed to use the same logic in html layouts to handle javascript files without success. All I need is not repeat javascript code in various erb templates that have 90% of identical code. - I can''t use more than 1 js file. - If isn''t a way to do this like erb can do in html, what''s the best way to "include" a file in another using Merb? -- from

I believe that I made a boo boo recently when recovering some unused disk space. Without going into painfully embarrassing detail I need to delete an entry in fstab for a now non-existent logical volume. The system reports that the there is a bad superblock for said logical volume. Mainly I expect because there isn't one anymore. How do I edit fstab so as to remove the mount request? For

I was wondering if anyone could help me with this one. I am having trouble getting LDAP and samba working properly on my Debian Woody box. I am using OpenLDAP 2.0.27-3 and the unsable packaged Samba version 2.999+3.0 and am using the samba.schema for my LDAP database. Whenever I try to join the network using either W2K or smbclient the LDAP debug log shows that the following filter is being

Hi everyone, I''m looking for a shortcut to finding and updating or creating record depending on the results of the find. So, is there a shorter way to do it than this? @stuff = Stuff.find_by_foo_and_bar("yay","hooray") if @stuff: Stuff.update(@stuff.id, {:foo => "boo", :bar => "hoo"}) else Stuff.create({:foo => "boo",

As I shared on this forum last week, I did a bad boo boo when I erased my /boot/ directory without a backup - all of the things I caution other NOT to do. Nevertheless, after trying to put things back in order, today I decided to try a reboot and I get a GRUB prompt. Next I have put my Linux 4 disk in the CD drive and have selected the "linux repair" mode which has put me into the

Thanks to the help of people from this forum I was able to bootstrap my data and then apply a model to it. Thanks for all your help. Everything worked out well, but I am having a difficult time getting the new parameter values. I bootstrapped the data 300 times and I want to get the 300 sets of parameter estimates and plot them in Excel. Here is my code:

It seems like a very common expectation that the following code would work: class boo { $me = "/something" file { $me: ensure => present } } class yay inherits boo { $me = "/something/else" } Yet, as many have found to their chagrin, it does not work. Should it? I believe I know how I could make this work: Create a single variable namespace for class

If you want to know which functions are (or may be) called from where, in the entire program, then you will need to do some sort of "LLVM-IR Linking" (there are tools that will do that for you, such as "llvm-link"). Of course, even then, there's possible cases where it's impossible to know whether a function is ACTUALLY called until at runtime - function pointers,
