For the record, r-fiddle is maintained by datacamp:

Dear List, According to datacamp support team, r-fiddle.org is not supported. We asked them to put it down as Professor Maechler suggested it is a waste of time for the R-help to respond to questions on something not maintained and severely outdated. If you would like to use R from your browser, you can embed the following into a web page: <script

Hola a tod en s: ¿Sabéis si en estos momentos hay o va a haber algún curso online de R gratuito?. O en el caso de que haya que pagar, ¿hay alguno económico?. ¿Alguna página web buena para mirar todo este tipo de cosas?. Gracias de antemano. Saludos, Marcos [[alternative HTML version deleted]]

Hello, All: Jonathan Baron is "giving up" maintaining the RSiteSearch database. This breaks three things: (1) The R Site Search web service that Baron has maintained. (2) The RSiteSearch function in the utils package. (3) The sos package, for which I'm the maintainer and lead author. Might someone else be willing to take these over? For me,

Hola, después de bastante tiempo usando con éxito rattle en R2.13 (windows y linux), he intentado instalarlo en el reciente R2.14 en plataformas windows (xp 32 y win2003-serv-64 bit) y me da infinitos problemas. Siempre falla algo relacionado con GTK+ y la URL que salta no funciona. Buscando ayuda en internet encuentro información casi que contradictoria. ¿Alguno puede recomendar un sitio que le

Don't do anything yet. I may have found the problem by accident. I tried to use the computer from something else, and it was being drastically slowed down by some leftover processes, which turned out to be xlhtml. That is something that converts Excel files. Apparently, some excel files got into the libraries, and they were causing the indexing to hang completely. I am now running everything

Hello, I'm trying to do two things: -1. Ensure that I understand how quantmod adjust's OHLC data -2. Determine how I ought to adjust my data. My overarching-goal is to adjust my OHLC data appropriately to minimize the difference between my backtest returns, and the returns I would get if I was trading for real (which I'll be doing shortly). Background: -1. I'm using Alpha

Hi All, I am addressing this post to all who are new to R. When learing R in the last weeks I took some notes for myself to have code snippets ready for the data analysis process. I put these snippets together as a script template for future use. Almost all of the given command prototypes are tested. The template script contains snippets for best practices and leaves out the commands that

Buenas, Alguien puede recomendarme un manual avanzzado de R, que me enseñe por ejemplo como aplicar tapply con sacar la pendiente de una recta, y cosas así. Gracias Jesús [[alternative HTML version deleted]]

Hola, ¿qué tal? Juanjo Gibaja y yo hemos organizado un curso de R básico, no presencial, colaborativo y gratuito dirigido a aquellas personas que quieren introducirse en el mundo de R. Para más información, pueden consultarse los dos siguientes enlaces: http://www.datanalytics.com/blog/2012/06/01/curso-de-r-gratuito-no-presencial/

Y para completar, también existen las reference class o las más modernas R6. https://adv-r.hadley.nz/r6.html Que se parecen más a los lenguajes más orientados a objetos, con sus herencias y demás historias. dom., 9 dic. 2018 17:23, Carlos J.

Hi R Helpers, I recently tried to take advantage of the ability to download all the tickers in the S&P 500 using the functionality of tidyquant, but it threw an error. For summary, the set of commands that I ran was library(tidyquant) tq_index_options() tq_index("SP500") sessionInfo() R feedback including error message and sessionInfo are provided below. Guidance would be

La verdad es que todas las aportaciones son muy muy interesantes, MI pregunta siguiente: Habeis usado R para programar orientado a objetos alguna vez? Porque yo hago mucho scripting.... Supongo que por mi mala calidad como programador...

R-help, In the following loop : for(i in 1:8) { cc[[i]]<-tapply(test[,i+6],list(puntar=test$puntar),sum)/tapply(test[,5],list(puntar=test$puntar),sum) cbind.data.frame(cc[[1]],cc[[2]],cc[[3]],cc[[4]], cc[[5]],c[[6]],cc[[7]],cc[[8]]) } Is there anyway I can 'cbind.data.frame' the objects cc[[ i ]] without actually writing every single element?? In this case there are 8 but what if

Hi all, I have a data frame in which one column(PUNTAR) is of character type. What I want is to retrieve is the frame but only with those rows matching elements of PUNTAR with a list characters (e.g c("IX49","IX48") ) Year TUR STODNR PUNTAR 1994 9412 94020061 IX49 1994 9412 94020062 IX48 1994 9412 94020063 X32 1994 9412 94020065 X23 1994 9412

sorry for my previus (WRONG) answer, as someone already pointed out a solution could be subset(data, PUNTAR==c("IX49","IX48")) > -----Messaggio originale----- > Da: Guazzetti Stefano > Inviato: venerd?? 23 luglio 2004 15.55 > A: 'Luis Rideau Cruz'; r-help at stat.math.ethz.ch > Oggetto: R: [R] retrieve rows from frame assuming criterion > >
