similar to: functions as arguments to ther functions with inlinedocs

Dear list members, I use the package inlinedocs to create documentation for a package that I am building. The function package.skeleton.dx() is used to convert the source *.R file into the *.Rd documentation file. Usually this works like a charm, but on several occasions I got messages like this one: extra.code.docs prefixed.lines extract.xxx.chunks title.from.firstline

Dear list members, is it somehow possible to include figures to the html help pages of individueal functions (containing for example a plot produced by that function?) I thought about adding these figures into a 'graphs' subfolder of the package folder and then to somehow insert some sort of html link into the documentation code. I use inlinedocs for creating the documentation. Any

For documentation we use a system that generates Rd files from special comments in the code. (inlinedocs). It is crucial to be able to get the defining source code for objects like methods to extract the comments from it. Here is an R session that shows how this works for several kinds of methods and (at the end of the session) how if fails for methods of "initialize" >

Dear List, i run R non interactively and use option(error = dump.frames) to reconstruct the cause of errors for debugging. One of the functions in the call stack however uses the "..." (dot dot dot) argument. When I run debugger() and try to browse to this functions' environment I get the following error message: Error in get(.obj, envir = dump[[.selection]]) : argument

Dear all, I just noticed, that prompt () looses backticks that protect default arguments: f <- function (FUN = `*`) {} cat (prompt (f, NA)$usage) yields: \usage{ f(FUN = *) } %- maybe also 'usage' for other objects documented here. without the backticks, which is of course found by R CMD check as syntax error. While this is easily fixed if the .Rd is further edited manually, I

Dear list, this might be an easy one, but I could figure out a solution (or how to google the right term). Is there any way to test whether all elements of a vector are identical? For numeric vectors I would use sum(diff(vector)==0)==0 but I have character vectors. Any Ideas? Cheers Jannis

Dear list members, is it possible to set some options only inside a function so that the original options are restored once the function is finished or aborted due to an error? Until now I do something like: dummy=function() { old.options=options(error=dummy1()) .... options(old.options) } This works for most cases but when the function terminates because of an error and its last

Dear list members, I frequently program small scripts and wrap them into functions to be able to check them with checkUsage. In case these functions (loaded via source or copy pasted to the R console) use functions from other packages, I get this error: no visible global function definition for ?xxxxxxx? For example: test = function() { require(plotrix) color.legend() }

Dear List, does anybody has experience with the RNetCDF package? I manage to open a connection and copy data from a ncdf file but would need a way to automatically retrieve variable names (ideally all of them from one file) and units from the file. Any ideas? Jannis

Dears, a way to define x and y positions in plots in relative numbers (e.g in fractions between 0 and 1 referring to relative positions inside the plot region) would really help me. One example I would need this to would be to add text via text() to a plot always at a defined spot, e.g the upper left corner. Until now I always determined maximum x and y values and used those, but defining

Dear list memebers, I am stuck with using regular expressions. Imagine I have a vector of character strings like: test <- c('filename_1_def.pdf', 'filename_2_abc.pdf') How could I use regexpressions to extract only the 'def'/'abc' parts of these strings? Some try from my side yielded no results: testresults <-

Hi everybody How do I do to calculate the median and average of a colum of time data like this: "8:50:10". I also need to plot the time difference between two colums Thanks a lot -- View this message in context: http://n4.nabble.com/median-for-time-data-tp932287p932287.html Sent from the R help mailing list archive at Nabble.com.

Dear R community, I have a general question regarding indexing in multidiemensional arrays. Imagine I have a three dimensional array and I only want to extract on vector along a single dimension from it: data <- array(rnorm(64),dim=c(4,4,4)) result <- data[1,1,] If I want to extract more than one of these vectors, it would now really help me to supply a logical matrix of the

Dear list, is there a function in R that returns the product of a vector? E.g. if the vector is c(1,2,3,4) it should return 1*2*3*4=24 Cheers Jannis

Dear R developers, as far as I understand the manual of list.files(), there is only a way to exclude directories from the returned vector if you use list.files recursively. In non recursive mode, there seems to be no way of excluding directories (the include dirs argument does not seem to have any effect). Would it not be more intuitive and practical to allow the switching off of directory

Hi all, I am interested in the spill code which is produced by the register allocators. Therefore I wanted to ask if there  is some Documentation in which these allocators are described, or  that explains  how the register spilling works in detail. Regards Jannis

Dear List, i would like to mimic the behaviour or the following indexing with a do.call construct to be able to supply the arguments to `[` as a list: test = matrix[1:4,2] result = test[2,] My try, however, did not work: result = do.call(`[`,list(test,2,NULL)) result = do.call(`[`,list(test,2,)) result = do.call(`[`,list(test,2,'')) How can I use the do.call in that way with

Dear R community, I am running some rather large scripts either by executing single blocks of them separately or by executing them at once via source('script.R') Now there is a lot of code in those scripts that I only want to run when I run them manually, so I wonder whether there is any way to automatically find out whether the script is run manually stepwise or whether it is run via

Dear list, this may not be related to R but rather to my OS, but I do not understand the issue of compiling R packages deeply enough to figure out the exact cause of the problem. I am trying to install a R package from source as it is not yet available under Cran (Rssa, downloaded here: https://github.com/asl/rssa). Running sudo R CMD INSTALL asl-rssa-6f458e4.tar.gz from the console
