Problems in package management after Linux system upgrade
I upgraded from Fedora Core 4 to Fedora Core 5 and I find a lot of
previously installed packages won't run because shared libraries or
other system things have changed "out from under" the installed R
libraries. I do not know for sure if the R version now from
Fedora-Extras (2.2.1) is exactly the same one I was using in FC4.
I see problems in many packages. Example, Hmisc:

Capturing the expression representing the body of a function
Hi all,
What's the preferred way of capturing the expression representing the
contents of a function?
* body(write.csv) gives me a braced expression
* body(write.csv)[-1] gives me a mangled call
* as.list(body(write.csv)[-1]) gives me a list of calls
* as.expression(as.list(body(write.csv)[-1])) is what I want but seems
like too much work
Any suggestions?
Thanks,
Hadley

mac question
Hi there,
currently, I've updated R on my Mac (OS X) to version 2.10. I was
wondering if I have to install all additional packages again???
In Windows, I just needed to copy the library folder of the old
installation but how does it work with Mac?
Can anybody give me a hint?

Roxygen2: version 2.2
# Roxygen2
The premise of `roxygen2` is simple: describe your functions in
comments next to where their definitions and `roxygen2` will process
your source code and comments to produce R compatible Rd files.
Here's a simple example from the `stringr` package:
? ? #' The length of a string (in characters).? ? #'? ? #' @param
string input character vector? ? #' @return numeric

sysdata.rda, namespaces and package dependencies
Hi all,
I'm struggling with accessing a package dataset (munsell.map, stored
in sysdata.rda) when that package is imported, not required. A simple
reproducible example is:
install.packages("munsell")
munsell::mnsl("10B 4/6")
# Error in match(col, munsell.map$name) : object 'munsell.map' not found
library(munsell)
munsell::mnsl("10B 4/6")

NEWS and readNEWS
readNEWS() states:
Read R's ?NEWS? file or a similarly formatted one. This is an
experimental feature, new in R 2.4.0 and may change in several
ways
and news() also indicates that this tool is supposed to work with
non-R news files. However, I've not been able to get readNEWS to read
a package news file, even when following the format indicated in
news(). Looking at the

Debugging namespace problems
Hi all,
I frequently find that I've failed to export something in my NAMESPACE
and hence my package doesn't work when it's imported into another
package. Does anyone have suggestion for debugging this type of
problem? R CMD check passes without any ns related errors on both the
importee and the importer.
I've attached a reproducible example - if you install the development

Package Dependency
Lately, I see a dependency problem with R-3.2 systems.
install.packages allows dependencies, but they are not installed so
the install fails.
I see this a lot with students who are able to install packages like
ggplot2 but then can't load it because a dependency "stringi" is
missing. Those students are generally using Windows, but today I
reproduced the same on RedHat Linux with

How to detect if a vector is FP constant?
Hi all,
What's the equivalent to length(unique(x)) == 1 if want to ignore
small floating point differences? Should I look at diff(range(x)) or
sd(x) or something else? What cut off should I use?
If it helps to be explicit, I'm interested in detecting when a vector
is constant for the purpose of visual display. In other words, if I
rescale x to [0, 1] do I have enough precision to get

Base function for flipping matrices
Hi all,
Are there base functions that do the equivalent of this?
fliptb <- function(x) x[nrow(x):1, ]
fliplr <- function(x) x[, nrow(x):1]
Obviously not hard to implement (although it needs some more checks),
just wondering if it had already been implemented.

require is to suggests as what is to imports?
Hi all,
If a package suggests another package in its description, you can
check it at runtime with requires. How do you do check if a package
is available without loading it, if you only want to access one
function in the package namespace.
Thanks,

Quelplot
Hi all,
Does anyone have an R implementation of the queplot (K.?M. Goldberg
and B.?Iglewicz. Bivariate extensions of the boxplot. Technometrics,
34(3):pp. 307?320, 1992)? I'm struggling with the estimation of the
asymmetry parameters.

License of R manuals
Hi all,
Under what license are the R manuals (R language definition etc)
released? They are not mentioned explicitly in license() and have no
license information in the individual documents. Does this mean that
they are released under GPL-2? If so, what does that mean, given that
they aren't software?

Save and serialize
Hi all,
Is there any relationship between save and serialize? Do they use the
same algorithm?

Substitute adds id attribute?
Hi all,
I can't figure out how to make this problem easily reproducible, but I
can demonstrate it very simply, so I hoped someone might be able to
suggest a place to start:
> f <- function(x) substitute(x)
> f(x)
x
> f(mpg)
mpg
attr(,"id")
[1] 11
It works as expected in a clean R session:
> f <- function(x) substitute(x)
> f(x)
x
> f(mpg)
mpg

Version of substitute that evaluates it's first argument
Hi all,
Does there already exist a version of substitute that evaluates it's
first argument? (i.e. it accepts an already quoted expression). This
seems like something that's pretty handy, but I haven't found any
existing function to do it:
substitute_e <- function(expr, env) {
eval(substitute(substitute(expr, env), list(expr = expr)))
}
f <- quote(x + y + z)

Persistent storage between package invocations
Hi all,
Does anyone have any advice or experience storing package settings
between R runs? Can I rely on the user's home directory (e.g.
tools::file_path_as_absolute("~")) to be available and writeable
across platforms?

Line plots in base graphics
Am I missing something obvious on how to draw multi-line plots in base graphics?
In ggplot2, I can do:
data(Oxboys, package = "nlme")
library(ggplot2)
qplot(age, height, data = Oxboys, geom = "line", group = Subject)
But in base graphics, the best I can come up with is this:
with(Oxboys, plot(age, height, type = "n"))
lapply(split(Oxboys[c("age",
