timeBasedSeq stumbles over the year 2038 (xts package)
I have the following problem:
As expected I obtain
timeBasedSeq( 2037/2037)
[1] "2037-01-01"
>
However if I do the same for 2038 I get
timeBasedSeq( 2038/2038)
[1] "2038-01-01" "2039-01-01"
I get the same strange result if I use later years or any interval that contains 2038:
timeBasedSeq( 2037/2039)
[1] "2037-01-01" "2038-01-01"

what does .indexDate() do - R::xts
Dear R experts,
I am learning the very useful XTS package, but cannot figure out the
purpose of some commands.
in particular, the .indexDate() command does not work as expected.
say:
x <- timeBasedSeq('2010-01-01/2010-01-02 12:00')
x <- xts(1:length(x), x)
then i can subset on date as follows:
x['2010-01-01']
however the .indexDate() command does not work as expected;

[LLVMdev] Private headers and testing
Hi all,
Reading this doc:
http://llvm.org/docs/CodingStandards.html#hl_privateheaders, it suggests
putting private implementation details outside of llvm/include/* to avoid
polluting the public header space. This makes sense, and it works fine,
because make enters every directory and hence doesn't need a -I path to
include them.
However, unittests need to also #include these headers to be

Convert Numeric (20090101) to Date
Hi there,
Does it exist where R can convert a numeric date (20090101) to a "proper"
date format? (Ideally dd-mm-yyyy)
Original data (in this case) is in .DAT format. I read the multi-column
data with the read.fwf function, where I specified the column width for the
eight digit date (example above). After the .DAT data is read-in &
formatted in R, it is to be exported to Excel.

[LLVMdev] New .ll parser
I just checked in a new parser for .ll files, deleting the old bison
parser. This means that the last of the ".cvs" files are gone from
the tree, which will hopefully make the world a happier place for
windows users in particular. I tested it thoroughly but expect minor
fallout, if you notice any problems, please let me know.

rbind, data.frame, classes
Hi,
This has bugged me for a bit. First question is how to keep classes with
rbind, and second question is how to properly return vecotrs instead of
lists after turning an rbind of lists into a data.frame
list1=list(a=2, b=as.Date("20090102", format="%Y%m%d"))
list2=list(a=2, b=as.Date("20090102", format="%Y%m%d"))

some patches and remarks for ng
1 patch for libnouveau_drm, 4 for drm and one work in progress patch

Getting nv50 to run proved to be more difficult than i thought (at
some point i stopped because it would require significant changes), i
just have a few remarks.
- Buffer object access is not guarded by fences at all, which is a
major issue. You worked around that by using M2MF I suppose, but this

removing specific rows from array
I'm attempting to create an array of treatment comparisons for modelling data generation. This involves comparison of one treatment (c2) with another (c3), relative to a common comparator (c1).
Attached code gives me the correct array but need to remove duplicates. Duplicates relate only to c2 and c3
such that I need to remove
r3 because c2 and c3 are same as r1 with c2 and c3 swapped

Importing an Excel file that has merged cells
Dear all,
I have a problem with importing an excel file into R. I can open the
file easily (either saving it as a CSV or using RODBC). But the
original file is using merged cell in its first column, which gives
the name of the observation. (I am dealing with repeated measurements
for the same observation)
So when I open the dataframe in R it looks like this

Updated comment padding patches
I've attached updated patches (against vorbis-tools 1.3.0b3.5) to
support comment padding. No changes to libvorbis are necessary. The
padding is added in the same way as oggenc2 (null bytes within the
packet, at the end) and shouldn't cause problems with any reasonable
decoder or comment editor implementations.
Padding is enabled by default, except for small files (less than 30 s

temporal evolution and variance after rotation of eof
Dear R users,
I have been doing some eof analysis using princomp function, then the eof
results were rotated with varimax and promax functions. Those functions are
working fine. However, after their uses, I cannot find how to obtain the
temporal evolution and the variance of the obtain components, as varimax and
promax does not have the arguments $scores and $sdev.

Temporal disaggregation using interpolation splines
Hi,
this is a newbie question. Would it be able to convert e.g. annual
time series of flow data (or an index series) into quarterly data using
interpolation splines by means of an existing R-function? The problem is,
that the average value of the computed quarterly values must be the annual
value, i.e. the spline should cross the annual values (in a stairs-line
plot) in the middle of every annual
