Request: Increasing MAX_NUM_DLLS in Rdynload.c
...ll hit
the MAX_NUM_DLLS error, meaning we'll have to break them down further (or
maybe we can be clever with gcDLLs()?). I'm CC'ing Lars Kotthoff and Bernd
Bischl to make sure I am representing the issue well.

...to 100 for a very particular reason than I apologize, but if it is possible
to increase MAX_NUM_DLLS it would at least make the testing at mlr much
easier.
I understand you are all very busy and thank you for your time.

Why is the diag function so slow (for extraction)?
Looks like the c(x)[...] bit used to be as.matrix(x)[...]. Not sure
why the change was made many years ago, but this was before names were
handled explicitly. It would definitely be better to not force the
duplicate, at least in the case where we are sure c() and [ would not
dispatch.
Best,
luke

But then you should use Factor Analysis which has that concept of ?noise? (unlike PCA).

The common case is that the remainder terms have a roughly _constant_, small-ish variance and are interpreted as noise. Of course the magnitude of the noise is important information.

...l variances are "uninformative", so that you can make do with only the first handful regressors. I tend to interpret "uninformative" as "noise-like" in these contexts.

summary( prcomp(*, tol = .) ) -- and 'rank.'
Following from the R-help thread of March 22 on "Memory usage in prcomp",
I've started looking into adding an optional 'rank.' argument
to prcomp allowing to more efficiently get only a few PCs
instead of the full p PCs, say when p = 1000 and you know you
only want 5 PCs.

Unable to Install Packages from Binaries on Windows for R 3.2.3
Installing packages from binaries on Windows seems broken, when using
mirrors that are up to date with CRAN
install.packages(

type = 'binary',

)
Changing repos to the Kansas CRAN mirror installs the package as expected,
but that could be because the KS mirror has not yet synced.
