Hi all, I thought I would post code to send an email out of R. The code uses Grothendieck and Bellosta's interface package rJython for executing Python from R. The code itself provides basic email functionality for email servers requiring authentication. It should be easy to extend it (e.g., for sending attachments). I hope it's useful. require(rJython) rJython <- rJython()

Hola, Tengo un problemillo con el encoding de unas palabras y trabajarlas en R por medio de rJython. Os explico: cuando quiero utilizar cualquier dato que contenga acentos o eñes o cualquiera de estos caracteres que no usan los angloparlantes obtengo un error. Ejemplo, en R: > jython.call(rJython,''ascii'',''señoría'') Error en jython.exec(rJython,

Dear R People: I have been experimenting with rPython, rSymPy, and rJython. Here is my latest snag: > library(rJython) Loading required package: rJava Loading required package: rjson > library(rSymPy) > rJython <- rJython() > x <- "x" > y <- "y" > rJython$exec("from sympy import *") Error in .jcall("RJavaTools",

Hello, Does anyone know how to convert this: > msg [1] "a" [2] "b" [3] "c" To: > msg "a b c" In other words, I need to convert a character vector to a single string with carriage returns for each row. Functionally, I'm attempting to send an email of a character vector in a way that is readable in the email body. I can only input one

Hola, ¿qué tal? Estoy buscando "alpha testers" para mi paquete rPython. El paquete es la evolución natural de rJython, un paquete de R que permite llamar a Jython, el dialecto de Python que corre sobre la máquina virtual de Java, desde R. rPython permite llamar al verdadero Python. Funciona perfectamente en mi máquina, pero necesito ver qué problemas de instalación y uso aparecen en

Yes, lots of packages do use C/Fortran code ... it would be great if there were more packages that are "pure R" especially since the advent of S4 classes and namespaces. Is it worth suggesting that we create a designation "pure R" for packages that have no external source code and encourage more of these? Indeed, now the number of packages is so big could they be classified to

I'd like to develop, if there is not one already, an interface between R code and Haskell code, to allow R code to call Haskell (compiled) code, and vice-versa. But in the interest of not reinventing the wheel, does anyone on this list know of existing bindings for Haskell code? There is support for loading plugins in Haskell, and for an eval() like set of functions provided by the Haskell

Hello, What is the best way to turn a matrix into a list removing NaN's? I'm new to R... Start: > mt = matrix(c(1,4,NaN,5,3,6),2,3) > mt [,1] [,2] [,3] [1,] 1 NaN 3 [2,] 4 5 6 Desired result: > lst [[1]] [1] 1 3 [[2]] [1] 4 5 6 Thanks! Ben [[alternative HTML version deleted]]

Hello, I'm attempting to return the date (in form '%Y-%m-%d') of the Monday previous to the current date. For example: since it is 2011-09-02 today, I would expect 2011-08-29 to be the return value.

Big news for all Java programmers out there. Now you can use Cucumber with pure Java! That''s right, you don''t have to write a single line of Ruby! (1) All of your step definitions can be written as annotated methods in POJOs (Plain Old Java Objects). To get a taste of what this looks like, check out the simple example in the cucumber_java project on GitHub: * README for

Hello, Does anyone know how to change the Tinn-R editor background color? White is rough on the eyes... Thanks, Ben [[alternative HTML version deleted]]

Can someone show me how to modify one (R.oo) class's object inside another (R.oo) class's method? Is that possible with the R.oo package? A quick example or reference to an example would be outstanding... Thanks, Ben [[alternative HTML version deleted]]

Hello, I have a bunch of data files all with "dbs" file extensions. They are generated via a SQL query from another program and source. Does anyone know (or have ideas) how to get the data from a dbs file type into R (or into some other format that can imported to R)? I've searched online for 4 hours now... Thanks!

Hello, There has to be a more R'ish way to do this. I have two matrices, one has the values I want, but I want to NA some of them. The other matrix has binary values that tell me if I want to NA the values in the other matrix. I produce a third matrix based on this. I've also tried apply() passing in c(1,2) for rows and columns with no success yet. Example (this works, but I'm

Hello, I'm trying to get the count of values in each row that are above and below quantile thresholds. Thanks! Example: > x = matrix(1:30,5,6) > x [,1] [,2] [,3] [,4] [,5] [,6] [1,] 1 6 11 16 21 26 [2,] 2 7 12 17 22 27 [3,] 3 8 13 18 23 28 [4,] 4 9 14 19 24 29 [5,] 5 10 15 20 25 30 > qtl = t(apply(x, 1,

Dear R users, I have been using rsympy to solve a set of simultaneous equations from R. There are two solutions for the variable I'm interested in, xx[0] and xx[1], which are in terms of symbols called lam and conc. I'd like to pick out the one which is positive at (lam=0, conc=0) and call it mysol. In python I could write: if (xx[0].subs(lam,0)).subs(conc,0)>0: mysol=xx[0]

Hello, I'm looking to get the values, row names and column names of the largest and smallest values in a matrix. Example (except is does not include the names): > x <- swiss$Education[1:25] > dat = matrix(x,5,5) > colnames(dat) = c('a','b','c','d','c') > rownames(dat) = c('z','y','x','w','v') >

Hello, I'd like to 'do work' on data members upon construction (i.e. without implementing it in a get method). Is this the best way to create data member 'z' upon construction? I'm thinking if .z=paste(x,y) below gets more complex I'll run into issues. setConstructorS3("MyClass", function(x=NA,y=NA,...) { this <- extend(Object(), "MyClass",

Hello, Using the R.oo package, how do I throw an error if a field is not present when the user of the class creates the object?
