I am new to R programming but have dived into a medium sized modelling software
development project.
Having come from a Java OO background I have a couple of questions about S4
objects.
Is there a way to make S4 slots (and methods) private and hence force the use
of accessor methods?
Is t
In R 2.8.0/Windows:
> lag(1)
[1] 1
attr(,"tsp")
[1] 0 0 1
Though this has the 'tsp' attribute, it is of class "integer", and hence not
a "time-series object" as defined by ? ts: "time-series objects... are
vector [sic] or matrices with class of '"ts"' (and additional attributes)".
? lag further
It looks like the 'seq' variable to 'for' can be altered from
within the loop, leading to incorrect answers. E.g., in
the following I'd expect 'sum' to be 1+2=3, but R 2.10.0
(svn 48686) gives 44.5.
> x = c(1,2); sum = 0; for (i in x) { x[i+1] = i + 42.5; sum = sum +
i }; sum
[1] 44.5
or,
Hi list,
This looks similar to the problem reported here
https://stat.ethz.ch/pipermail/r-devel/2006-April/037199.html
by Henrik Bengtsson a long time ago. It is very sporadic and
non-reproducible.
Henrik, do you remember if your code was using reg.finalizer()?
I tend to suspect it but I'm not

Hi,
The following idea only partially answers your question
I have successfully written a GUI using the tcl/tk package that ships
with standard R. It is then possible (in Windows) to create a shortcut
icon that runs the following command:

Dear Christian,
your question does not at all belong to R-devel.
Please use R-help instead,
but you should probably first read the posting guide,
(and from that see that you should *not* send HTML-ified
postings).

Hi,
i did a mistake with my first post.
I have to reshape data from this matrix:
idx1 x2 x3x4day1 day2 day3 day4 day5 day6 day7

This seems to be as documented. From ?lm
All of 'weights', 'subset' and 'offset' are evaluated in the same
way as variables in 'formula', that is first in 'data' and then in
the environment of 'formula'.
