similar to: [R] Function hints

I would like to follow up on another one of the documentation issues raised in the discussion on function hints. Duncan mentioned that the R core were working on preprocessing directives for .Rd files, which could possibly include some sort of include directive. I was wondering if a "includeexamples" directive might also be considered. It often makes sense to use the same example to

One of the recurring themes in the recent UserR conference was that many people find it difficult to find the functions they need for a particular task. Sandy Weisberg suggested a small idea he would like to see: a hints function that given an object, lists likely operations. I've done my best to implement this function using the tools currently available in R, and my code is included at the

The sound file is played correctly for the first time, then when rewind to the initial position. then copy PCM to buffer, the OpenAL report an error. It seems like the OpenAL doesn't recognize the PCM data. The OpenAL error number : AL_INVALID_VALUE 0xA003 void Buffer::PCMData (ALuint id, ALenum eFormat, ALvoid *data, ALsizei size, ALsizei freq) { // Copy

Hi listers, I am having some trouble in a matrix multiplication... I have already checked some posts, but I didn't find my problem... I have the following code... But I am not getting the right multiplication... I checked the dimension and they are fine... id_y <- array(1:10,dim=c(2,1,5)) id_yt<-aperm(id_y,c(2,1,3)) m_id<-array(dim=c(dim(id_y)[1],dim(id_y)[1],dim(id_y)[3])) for (i in

I have a simple query as follows: "SELECT m_id,sale_date,YEAR(sale_date),WEEK(sale_date),return_type,DATEDIFF(return_date,sale_date) AS elapsed_time FROM risk_input" I can get, and view, all the data that that query returns. The question is, sale_date is a timestamp, and I need to call split to group this data by m_id and the week in which the sale occurred. Obviously, I would

You might want to have a look at 'source.mvb' & friends in the 'mvbutils' package. It's designed to allow control of nested sourcing, and to allow interspersed data and commands in a single self-contained file. Unlike 'source', 'source.mvb' reads each statement and immediately executes it, before proceeding to the next; hence it has do the parsing to figure

Hi, Reading help("Documentation"), I'm led to believe that a help call like: ?myFun(x, sqrt(wt)) Will search for help on the appropriate method in the case that myFun is generic. This isn't working for me. Here is an example using the Biobase package: ## If Biobase is not installed source("http://bioconductor.org/biocLite.R") biocLite("Biobase")

My last query related to this referred to a problem with not being able to store data. A suggestion was made to try to convert the data returned by fitdist into a data.frame before using rbind. That failed, but provided the key to solving the problem (which was to create a data.frame using the variables fitdist produces in the object it returns). I now have almost everything working as

>From the documentation I have found, it seems that one of the functions from package plyr, or a combination of functions like split and lapply would allow me to have a really short R script to analyze all my data (I have reduced it to a couple hundred thousand records with about half a dozen records. I get the same result from ddply and split/lapply: >

I must have missed something simple, but still, i don't know what. I obtained my basic data as follows: x <- sprintf("SELECT m_id,sale_date,YEAR(sale_date) AS sale_year,WEEK(sale_date) AS sale_week,return_type,0.0001 + DATEDIFF(return_date,sale_date) AS elapsed_time FROM `merchants2`.`risk_input` WHERE DATEDIFF(return_date,sale_date) IS NOT NULL") moreinfo <- dbGetQuery(con,

Hello, Is there a way to define a custom unary operator in R (other than making a class and 'overloading' the normal unary operators in R)? The documentation seems to suggest that only custom binary operators are possible with the ``%abc%``construct but I was wondering whether any one has done so. None of the RSiteSearch or RSeek queries I posed suggested that this question had

Dear list, We have encountered problems with the package mvbutils while creating (or reading from disk) timeSeries objects. Below is a very simple example of the problem. We are using R 2.12 in  a PC running Windows 7  64-bit Professional. ----------- library(timeSeries)   cv1 <- as.character(as.Date(1:10, origin = "1970-01-01")) ts1 = timeSeries(1:10, cv1, units = NULL)
