topenv of emptyenv
...r this result or if it?s ?accidental?/arbitrary:
the C `topenv` implementation defaults to returning R_GlobalEnv for an
empty environment. Is this effect actually useful (and used anywhere)?
This is in R 3.4.4 but I can?t find an indication that this behaviour
was ever changed.
Cheers

How do I reliably and efficiently hash a function?
I?ve got the following scenario: I need to store information about an
R function, and retrieve it at a later point. In other programming
languages I?d implement this using a dictionary with the functions as
keys. In R, I?d usually use `attr(f, 'some-name')`. However, for my
purposes I do not want to use `attr` because the information that I
want to store is an implementation detail that

(Still) no printing possible in wine 0.9.15
...sible at all.
Wincfg has a lot of options, but none of them seem to be related to cups or
printing, so now I'm stuck.
Maybe wine is generally unable to print, if the printer isn't connected
locally? (I believe not)
Can somebody please help me with this problem?
Thanks in advance

"reverse truncate" to extract only decimal values
hello there,
Is there a way of truncating in the opposite direction so as to retain only
the values to the right of the decimal??
i.e. rather than:
> trunc(39.5)
[1] 39
i would get something like:
> revtrunc(39.5)
[1] 0.5
I've been searching to no avail but I imagine there is a very simple
solution!

No printing possible in wine 0.9.15
...(Huw Davies) saying
that this is a bug that was fixed in wine-0.9.
None of these hints was of any help for me, and since wine switched from
config files to registry, searching for misconfigurations is a real pain,
if possible at all.
Can anybody please help me with this?
Thanks in advance

plot circular histogram
In conducting studies of animal orientation and displacement, I need to
produce circular histograms of angles (bearings in radians 0-2pi) where the
centre of the circle indicates very few observations for a given bin of
angles and outwardly concentric circles indicate greater frequencies of
observations for a given bin of angles. I'd like not to have to write the
function myself but I

Xen 3.0.2-2 + linux-2.6-xen-fedora
...an automatic reboot.
Does anybody know where to get some documentation on this or has any
experience with the fedora kernels?
I''ll give the other repository (linux-2.6.17-xen) a try later; maybe
that''ll work out better for me.

merge numerous columns of unequal length
I have numerous objects, each containing continuous data representing the
same variable, movement rate, yet each having a different number of rows.
e.g.
d1<-as.matrix(rnorm(5))
d2<-as.matrix(rnorm(3))
d3<-as.matrix(rnorm(6))
How can I merge these three columns side-by-side in order to create a table
regardless of the difference in length? I wish to analyze the output in a
spreadsheet

help with simple function
I have a matrix of frequency counts from 0-160.
x<-as.matrix(c(0,1,0,0,1,0,0,0,1,0,0,0,0,1))
I would like to apply a function creating a new column (x[,2])containing
values equal to:
a) log(x[m,1]) if x[m,1] > 0; and
b) for all x[m,1]= 0, log(next x[m,1] > 0 / count of preceding zero values
+1)
for example, x[1,2] should equal log(x[2,1]/2) = log(1/2) = -0.6931472
whereas x[3,2] should

Via EPIA Mini-ITX motherboard
Just to drag this thread on a bit further ...
I've been looking into these little boxes, thinking I could use one as a
firewall/gateway. My one requirement is that it would need to have two
PCI slots (one can be low-profile), and although I've seen PCI riser
cards that can give me two slots, they've been rare, and cases that are
suitable (i.e have the space, and back panels are

On implementing zero-overhead code reuse
I'm looking for a way to approximate the "zero-overhead" model of code
reuse available in languages like Python, Perl, etc.
I've described this idea in more detail, and the motivation for this
question in an earlier post to R-help
(https://stat.ethz.ch/pipermail/r-help/2016-September/442174.html).
(One of the responses I got advised that I post my question here instead.)

Calling a replacement function in a custom environment
...nt for `$`.
Am I overlooking something to make this work? And if not ? unless there?s a
concrete reason against it, could it be considered to add support for this
syntax, i.e. for calling a replacement function by `$`-subsetting the
defining environment, as shown above?
Cheers,
Konrad

Export kde object as shapefile
I am trying to estimate home range size using the plug-in method with kernel
density estimation in the kernel smoothing (ks) package. Unless there is
another way I am not familiar with, in order to calculate spatial area under
the space I need to convert my kde () object into a spatial object somehow
in order to calculate its spatial area. Could someone demonstrate how this
might be done?

nfs locking between current and stable
Hello,
I am attempting to get flock/file locking working between my -stable
(updated ~19 may) nfs file server and -current desktop; the server is
running lockd/statd, and both my mail client (mutt) and a simple perl
program complain that files on the nfs server cannot be locked.
I am aware that
there has been work on the nfs locking code in current, and have a vague
recollection of a workaround

Calling a replacement function in a custom environment

because of partial name matching. E.g. suppose b was a list containing
functions partial(), partial<-(), and part<-(), and I call
b$part(x) <- 1
what would be called?
