R Package Installation Ignores libPaths Setting
Good day,
I believe from the documentation that folders in R_LIBS should appear in the output of .libPaths, but they do not. The documentation contains "The library search path is initialized at startup from the environment variable R_LIBS ..."
However,
$ export R_LIBS=/users/stgrad/dario/tmp/
$ Rscript -e ".libPaths()"

Grapics Device Resolution Limits
Good day,
Could the documentation of graphics devices give some explanation of how big the bitmap limits are? For example,
> png("Figure1A.png", h = 7, w = 7, res = 1000, units = "cm")
Results in Error: unable to start png() device, but the help page of devices doesn't explain that there are any limits or how they are determined. The wording of the error message could

Grapics Device Resolution Limits
Note that there are at least 5 separate png() devices, so Linux was not
using the (default) device used on Windows.
In general, the device-limits info is not on the help page because we do
not know it. On Windows the default device limits depend on the OS
version, 32/64-bit, RAM and the graphics hardware. This sounds like the
last: you were asking for 49 megapixels which is far larger than

capture.output on S4 slot
Hello,
capture.output produces a different result if the S4 object was created with a constructor than if the body of the constructor is copied and pasted.

Can't Find Function After requireNamespace
I have a simple function :
f <- function()
{
if(requireNamespace("ggplot2"))
qplot(Sepal.Length, Petal.Length, data = iris, color = Species)
else
message("No graphics, just text.")
}
ggplot2 is in the Suggests field of the DESCRIPTION file. When I load the package, and run the function, I get an error :

S4 Method Dispatch for Class Defined as Attribute
Hello,
I am writing an interface to some functions from the CRAN package pamr, which is poorly written.
I have a S4 method I declared with setMethod. I'd like to provide a signature of "pamrtrained" which is the class of object that training creates. The last two lines of code of pamr.train are :
class(junk) = "pamrtrained"
junk
How can I dispatch on these kinds

Documentation for sd (stats) + suggestion
Good day,
It is implemented by the CRAN package multicon. The function is named popsd. But it does seem like something R should provide without creating a package dependency.

mcmapply Core Usage
Hello,
I have a minimal example that shows a problem I'm having with parallel processing.

}, as.list(1:10), as.list(10:1), mc.cores = 16, SIMPLIFY = FALSE)
I see "Running" printed once every ten seconds. I read the documentation for mcmapply, but I don't understand why it wouldn't

as.list method for by Objects
Good day,
I'd like to suggest the addition of an as.list method for a by object that actually returns a list of class "list". This would make it safer to do type-checking, because is.list also returns TRUE for a data.frame variable and using class(result) == "list" is an alternative that only returns TRUE for lists. It's also confusing initially that

The use of "rounding" also doesn't make sense. If The number is halfway between two integers, it is rounded to the nearest even integer.
