Partitioning an nxp Time series matrix
Hi,
I have an nxp data set of time series. For my final year project, I would
like to partition this data set into a smaller number of units ( < n). Where
each of the units contains time series that move closely together (i.e. in
unison), and the "simmilarity" (in terms of occurence & amplitudes of peaks
and troughs) between the segregated units is "low".
I know

Exporting objects plotted with plot3d() - rgl package
Dear all,
Can anybody tell me how to export a 3d figure made with the plot3d
function? I'm careless about whether it's still interactive or not in
another format, as long I can get it out of R.
Thanks!

Is it advisable/possible to default on Linux to an EDITOR that actually exists?
Michael,
This looks rather like a 'compile-time versus run-time' question to me. If
you look at etc/Renviron.in in the R sources you see a number of choices,
some of them with configure-time determined values (which I tend to override
with values for the Debian package).
For 'EDIT' it is
## Default editor
EDITOR=${EDITOR-${VISUAL-vi}}
giving us two env vars to override eg

The case for freezing CRAN
There is a central assertion to this argument that I don't follow:
> At the end of the day most published results obtained with R just won't be reproducible.
This is a very strong assertion. What is the evidence for it?
I write a lot of Sweave/knitr in house as a way of documenting complex analyses, and a
glm() based logistic regression looks the same yesterday as it will

It looks like R has defaulted to using 'vi' for file.edit() (via
EDITOR since ~24 years ago[1][2].
These days I think it is much more common to write code from
lightweight environments, e.g. Docker files which strip all
unnecessary commands. On such machines, it is not safe to assume 'vi'
is installed, and it's not uncommon to encounter an issue like I did
again today[3] where

Strange because in my all my experiments calling malloc.trim always helped
- memory reported by top decreased to the level it supposed to be. Do you
have in mind case when calling malloc.trim won't do anything? Also
shouldn't MALLOC_TRIM_THRESHOLD_ env variable has impact on malloc.trim
calls? At the moment seems any value is ignored...

Very interesting information about switching glibc malloc to jemalloc.
So I see action plan as following:
1. set up some benchmark (need to think about design)
2. Run it on ubuntu machine with default glibc malloc
3. Run it with malloc_trim passed with reg.finalizer()
4. Run it with jemalloc
5. Review results and if they will look better than with glibc malloc -
possibly
