Hi everyone, I''m a bit new to rails, but I have played around with it for the last month. I really enjoy programming in rails and I feel that I should program my new application through this framework. I am very exited when I start creating my scaffolds and views, there is some sense of accomplishment. Now I would really like to make a search function my page that would search through

Hi, This is my first time mailing to this site. I am running two different versions of Samba on two different servers. 2.0.6 on server A & 2.0.7 on server B In the smb.conf file for 2.0.6 I have a parameter, allow hosts=, that contains multipul IP addresses on each entry & in the global entry. On server B, 2.0.7, I do not have this parameter defined on any entry. My question is :

Dear All, I've been using R for windows for a while, without too many problems. However, I'm forced to use the MAC OS system for teaching, because our teaching labs are mac only (not my idea!!). I have a very basic problem, but one that doesn't appear on the FAQs. I simply want to import data from a spreadsheet. I'm using exactly what works fine on Windows, namely: 1 save

After getting one list done, I am now struggling to form a data frame in C. I tried to do a list of lists which gives me : $<NA> $<NA>[[1]] [1] "BID" $<NA>[[2]] [1] 0.6718 $<NA>[[3]] [1] 3e+06 $<NA> $<NA>[[1]] [1] "BID" $<NA>[[2]] [1] 0.6717 $<NA>[[3]] [1] 5e+06 $<NA> $<NA>[[1]] [1] "BID"

Hi, Does anyone know how I can retrieve a function name, for example If I have a function f as follows: f <- function( myfunc ) { print( name_of(myfunc) ); } I want to know what I should have as "name_of" such that I could call this with : f( median ) and it would print "median" or f( my_function_name ) and it would print "m_function_name". So far all I

Hi, I need to collapse a list into a string and then reparse it back into the list. Normally when I need to do this I simply use write.csv and read.csv, but I need to do this in memory within R rather than writing out to file. Are there any bespoke commands that any knows of that does something like this or any tips for doing this that anyone can suggest? I basically don't care

Hi everyone, Now I know there is information on this in the help files - which I have read. I am very close to implementing this but can't quite get how to remove this final hurdle. I have a DLL called "X.DLL" which I have no original code for, just the DLL. I have created a wrapper C file for the calls in X.DLL, and have successfully (I think) created a wrapper DLL for X

Hi Everyone I have a function f which does something using a function g. Function f is in a library and g has a default stub in the library but will be mainly overloaded in a later R script. For example: ########## In a compiled package 'P' ################# g <- function() { cat("Original function g"); } f <- function( newGsource=NULL ) { if(

Dear list, I want to run two independent calculation (A, B) and then combined their results to do a plot in R. Before I just run calculation A first, then calculation B. It will take some times. I just have one server with multiple core. I noticed that there are some nice package in R for parallel calculation, such as parallel, multicore and snow. Also there is a book, O?Reilly ? ?Parallel R,

Hi Everyone, I have a question about for loops. If you have something like: f <- function(x) { y <- rep(NA,10); for( i in 1:10 ) { if ( i > 3 ) { if ( is.na(y[i-3]) == FALSE ) { # some calculation F which depends on one or more of the previously generated values in the series y[i] = y[i-1]+x[i]; } else { y[i] <- x[i]; } } } y } e.g. >

Hi Everyone, I have a question about for loops.

Hi everyone, I have been attempting to build a very simple R package interfacing with some very simple C++ code. Everything I try though results in the function working but on return it produces a memory error. Here is the output: ***********OUTPUT*************************** > library(MyPackage) > hello(); *** caught segfault *** address 0x3, cause 'memory not mapped'

Hi everyone, I am trying to cross-compile a package I wrote using the Yan and Rossini tutorial "Building Microsoft Windows versions of R and R packages using Intel Linux". I have got reasonably far with this but when doing the linking using the line: i586-mingw32-g++ -shared -s -o mylibrary.dll mylibrary.def mylibrary.o mylibrary_res.o

Hi, I am not sure if this is just me using R (R-2.3.1 and R-2.4.0) in the wrong way or if there is a more serious bug. I was having problems getting some calculations to add up so I ran the following tests: > (2.34567 - 2.00000) == 0.34567 <------- should be true [1] FALSE > (2.23-2.00) == 0.23 <------- should be true [1] FALSE > 4-2==2 [1] TRUE > (4-2)==2 [1] TRUE >

Hi everyone, Have been trying to include windows.h (from MinGW) and R.h into a package and have found that Ralloc is coming up as a clash no matter which include ordering I use. In windows it has 2 arguments and is defined in objidl.h and in R.h it is 3 arguments. Any ideas of how to work round this? Have checked the web and have not seen anyone else comment on this. Many thanks Tom

Dear All, Does anyone use S or R for statistical natural language processing (NLP)? All I have found so far is a package called EMU (http://www.shlrc.mq.edu.au/emu/emu-splus.shtml) which is a speech wave-form processing package. What I'm looking for are routines to support text processing, text categorization, word sense disambiguation, text understanding etc. In particular, I would

Hi everyone, I am not sure this is possible so I would be interested in your responses. Say I have a variable 'v' with the string "myargument" in and I have a function 'f' that takes this argument as follows; f <- function( myargument=5 ) { ... does something... } Is there anyway I can say something like; f( v=10 ) such that it will be evaluated as f(

Hi, I have been studying the R manual on lists but cannot seem to create a simple R list in C - I keep on getting "'dimnames' applied to non-array" whenever I attempt to assign names to the list elements: Wanted output a list structure something like [ type="Bid", price=2.0, volume=1000 ] I can get up to a list of [ "Bid2, 2.0, 1000 ] But for the life of

Hi Everyone, When I have a load of functions which have various arguments passed via the ellipsis argument it keeps on assigning them as symbol making them unusable to the function. My current work around involves using do.call but this is rather cumbersome. Does anyone know why it suddenly changes the types to symbol and if there is a way to get the actual data pointed to by the symbol? (I

Hello, Just a quick question on best practise. I am converting quite a bit of legacy C code into R packages and have the following situation: (1) Legacy object with a double* array in, all over code so don't want to change any more than I have to. (2) Do something like: SEXP arrayToPassToR; PROTECT( arrayToPassToR = allocVector( REALSXP, n ) ); for(i=0; i < n; i++) {
