I just installed R-devel to check my package before submitting. I got an error in my vignette in regards to as.vector. When I looked at the code for as.vector in R-devel it is standardGeneric for "as.vector" defined from package "base" function (x, mode) standardGeneric("as.vector") <environment: 0x0918ad70> Methods may be defined for arguments: x, mode Use

Any insight into the behavior of "by" in the following case would be appreciated. There is a note in the help details for "by" about documenting behavior since v2.7 but I don't entirely understand what it is saying. I'm using R2.7.2 Windows. I'm interested if the following behavior was a change or whether it has always worked this way. I looked at

I spent a lot of time searching and came up empty handed on the following query. Is there an equivalent to rowSums that does product or cumulative product and avoids use of apply or looping? I found a rowProd in a package but it was a convenience function for apply. As part of a likelihood calculation called from optim, I?m computing products and cumulative products of rows of matrices with

> library(contrast) > contrast function (fit, ...) UseMethod("contrast") <environment: namespace:contrast> I guess the above function is S3. Could somebody let me know how to show the function body in an R session?

Dear R people, I have a simple question to ask. Suppose I have a data.frame with two variables: one factor (x) and one numeric (y), I want to calculate the mean of y for each value of x. Although it's easy to do it within a for a loop, I believe there may be a concise way by using some kinds of "apply" functions. Could anyone tell me how to do that? Thank you. Frank

Hi R-listers, I'm using R only for a few basic functions but am having difficulty doing something that *should* be simple. I have an nxn matrix, Q, where Q[i,j] is a directed value (in this case, oil exports from i to j). Note that Q[i,j]~=Q[j,i]. I imported column names along with the matrix then copied them to the rows using rownames(Q) <- colnames(Q). Simple so far. What I'd like

I found a tutorial for creating classes using generic functions ? S3 way ! It was short description so I couldn't grok in full its usage ... So far so good, what i currently do is something like this : Blah <- function(data,...) UseMethod('Blah') Blah.default <- function( ...... ) { self = .... class(self) <- 'Blah' self } Blah.some_method <-

Hi! Sorry for asking a trivial questions, but I can't seem to figure this out. I have a dataframe called master containing 30-odd variables. In this dataframe, I have observations across these 30 variables from 1930 to 2003 (I've made a "year" variable). How can I drop all rows for which the year is less than 1960? I'm assuming something with ifelse() but I can't

I have 3 packages on CRAN that I developed with my govt email address. I'll be retiring in a month and that email address will no longer work at some point. I realize that I need to change the maintainer address and I've already done that with one package but my question is do I need to remove all references to my govt email address listed as author in various files and replace with my

Thanks to Frank Harrell, Brian Ripley, Andy Liaw, Jeff Laake and Sean Davis for their usefull comments regarding "navigation" between valid R directories. Jeff recommanded the Mark Bravington package that can be found at: (ftp://ftp.marine.csiro.au/software/bravington/). I looked at the package and found that it can do a lot more than what I ask...

Thanks to Jeff Laake for giving me a starting point. It appears my zipping should have been: zip -r hello.zip hello essentially creating an outer folder having the package name inside the zip file. It still didn't quite work, with an error as follows: > utils:::menuInstallLocal() updating HTML package des...

Thanks to Max Kuhn, Jeff Laake, Duncan Murdoch, and Dirk Eddelbuettel, for their tips that eventually helped me get my teeth around this one. I'm in the process of documenting my experience, in case others find it useful. Please email me if you want to add to this or clarify anything. However, to close this thread, in a...

Hi all, I have just started using RMark to analyse capture-recapture data. I am trying to analyse a simulated data set using the Robust Design (two primary periods with three secondary sessions in each) to estimate apparent survival. On specifying the time intervals (that tell R about the primary and secondary sampling sessions), this is the error I get: > time.int <- c(0,0,1,0,0) >
