In the Green Book, section 7.5 discusses new vector classes and uses
quaternions
as an example of a vector class that needs more than one number per
element.
I would like to define a new class that has a numeric vector and a
logical
vector of the same length that specifies whether the measur

Hi Martin
thanks for this. I see what you say about R not being able to
magically subset the
"accuracy" slot. Which leaves me puzzled as to why anyone would define
a vector class such as "string" (p315). I can't see why "string" is
defined as
it is, rather than use something like "fungi" fr
You might want to look at the source for the R 'its' package. It defines
an S4 class for an irregular time series whose representation
consists of
1. a matrix portion analogous to your vector portion to hold the series
of multivariate series, and
2. a "dates" slot analogous to your accurate s

Is there any way to include warnings in the output from capture.output? eg:
a <- capture.output(warning("test"))
all.equal(a, "Warning message: \n test ")
Conceptually, this seems like redirecting stderr to stdout, or somehow
changing warning to simple print it's output. I've had a look at
tryC
CanUse?
If the 'Suggests' field "lists packages that are not necessarily needed"
(Writing R Extensions), then why is the user required to have the
package installed to pass R CMD check? Likewise, if a CanMakeUseOf field
is added, then why would one choose to use Suggests at all? That is, is
there
Rather than a plethora of fields, perhaps the Depends field could indicate
what depends on the object: For example, if we use file extensions to
indicate what is dependent then one might write this to indicate that
some .Rd (i.e. examples) and .Rnw (i.e. vignette) files depend on lattice
and the e
Something like this which displays the warnings and also writes
them to out so that they are captured:
out <- capture.output(
withCallingHandlers({
print(1)
warning("A warning.")
print(2)
warning("Another warning.")
print(3)
}, warning = function(x) ca

No one else seems to have responded to this.
Please see `Writing R Extensions' for how to time things in R.
For things like this, the fine details of how well the compiler keeps the
pipelines and cache filled are important, as is the cache size and
memory speed. Using

Following the discussion in "Writing R Extensions" in section 5.8.2, there
is no indication that showArgs expects a pairlist() instead of a list().
I was trying

When I use rgamma(n, shape, rate ) to generate gamma samples, it
gives zeros when both shape and rate are very small.
But we know that if x follows a gamma distribution, x should be positive.
It says clearly that showArgs is for use by .External, not .Call (it is
introduced in a paragraph about the differences):
@example
showArgs <- function(...) .External("showArgs", ...)
@end example
and that is the main user error here. Pairlists are not needed when used
as documented.
