Hi Max,
Here's a bit more information regarding the 'memory not mapped' errors which
occur in caret.
1. The segfault only occurs when knitting a Markdown file in RStudio. When the
code is run 'normally' in R, everything's fine.
2. The error is very hard to replicate! It only occurs when the fo
OK, thanks.
I haven't reported the memory map errors because I haven't been able to
replicate them reliably: some times they occur, but some times don't, for the
same code. I'll have another try, and will report if I can get more information.
Thanks again.

I'm using caret to assess classifier performance (and it's great!). However,
I've found that my results differ between R2.* and R3.* - reported accuracies
are reduced dramatically. I suspect that a code change to kernlab ksvm may be
responsible (see version 5.16-24 here:

Can anyone please shed any light on why R DateTimeClasses give weird times for
when daylight saving time information changes, and which aren't consistent with
the OS?
Example:

ggpairs() from GGally is fantastic, but I'm stuck trying to change the diagonal
labels and increase the size of the font in the diagonal axis plots.
I thought using ggally_diagAxis(... labelSize) would work, but it doesn't
appear to. I've tried the following three approaches, all of which don't
Despite lots of investigation, I haven't found any R packages might be suitable
for the following problem. I'd be very grateful for suggestions.
I have three-way nested data, with a series of measures (obs) taken in quick
succession (equal time spacing) from each subject on different days. The

I'm struggling with time zone version when expressed as hours offset from GMT.
Can anyone confirm that the behaviour below is incorrect? It seems that the GMT
offsets are backwards:
