similar to: A possible improvement to apropos

I've been experimenting with install.packages and it's new ability to track down dependencies from a list of repositories and encountered this: install.packages(c("foo", "bar"), repos="http://cran.r-project.org", dependencies=c("Depends", "Suggests")) dependencies 'foo' are not availabledependencies 'bar'

A further improvement to apropos() would be to sort the output. Currently, the output of apropos is in the order found on the search list and this will rarely be useful to the user. All that is needed is a sort(x) at the end of the function. + seth -- Seth Falcon | Computational Biology | Fred Hutchinson Cancer Research Center http://bioconductor.org

Hello, I'm starting working myself in the use of R, reading M. J. Crawley, The R Book. The problem I do encounter is concerning the commands apropos and find: > apropos(edit) Fehler: is.character(what) is not TRUE > find(edit) Fehler: is.character(what) is not TRUE I get the same error message typing anything else instead of "edit". The command ?edit seems to work well.

Dear all, Maybe, I am doing something wrong, but using R-2.5.0 on my Intel-Mac, I have problems using function callNextMethod() in method initialize. I am loading the following code as file "testS4.R": setClass("baseClass", representation(myname = "character", mydir = "character", "VIRTUAL"),

The old apropos started with: if (!is.character(what)) what <- as.character(substitute(what)) The new one has: if (character.only) stopifnot(is.character(what)) else what <- as.character(substitute(what)) i.e., the check for is.character(what) is missing. This has the effect that 'what' can no longer be a character string generated by a function call

?plotmath produces the helpscreen for plotmath. Why does apropos("plotmath") return only character(0)? > apropos("plotmath") character(0) > > version _ platform i386-pc-mingw32 arch x86 os Win32 system x86, Win32 status major 1 minor 4.1 year 2002

I'm looking for ideas for creating high-quality plots for use in projected presentations (powerpoint, etc) --- ideally high-quality png, jpg, bmp. The graphics produced using the postscript device look very good. Those generated with win.graph(), png are plagued by the jaggy lines. So far, the only way I can use the postscript plots in my presentations is using separate screen capture

Martin and I have `written' a function apropos() for finding all objects with names matching pattern. I attach code and documentation. Perhaps one could include it in the distribution proper. We are not sure about returning the position in the search list along with the matching names found. Martin thinks it should be on by default, I think it should be off so that the functions does the

Hi, Using latest R 2.5.0 Patched, I'm unable to install the Matrix package from cran.fhcrc.org.

Hi all, One of the things I find most problematic in R is the partial matching of names in lists. Robert and I have discussed this and we believe that having a mechanism that does not do partial matching would be of significant benefit to R programmers. To that end, I have written a patch that modifies the behavior of "[[" as follows: 1. [[ gains an 'exact' argument with

Hi, namespaceImportFrom in base/R/namespace.R has the following: fdef <- methods:::getGeneric(genName, impenv) The definition of getGeneric is in methods/R/RMethodUtils.R starts with: getGeneric <- ## return the definition of the function named f as a generic. ## ## If there is no definition, throws an error or returns ## NULL according to the value of

Git is a source code management system like CVS, svn, arch, and others. It would be nice to add exclude support to R CMD build and INSTALL so that the .git subdir of an R package is handled appropriately. Here is a possible patch: diff --git a/src/scripts/INSTALL.in b/src/scripts/INSTALL.in index 75da9db..09e5ab5 100644 --- a/src/scripts/INSTALL.in +++ b/src/scripts/INSTALL.in @@ -863,7

Hi the reference to R Internals https://cran.r-project.org/doc/manuals/r-release/R-ints.html#Tools in ?check (PkgUtils.Rd in utils package) is stale.

Does anyone have comments on the new wording here? Suggested: The Title field should be in title case.

Hi, I have a S3 package with namespace called "myS3Pkg". Inside my package I would like to create a S4 class which extends (adds 2 slots) another S4 class from some other package. The class should be created in "myPkg" environment (and not global environment). Using: setClass("myS4class", representation("otherS4class", mydata = "numeric"),
