Changes in xts 0.7-1:
o subsecond ISO8601 subsetting on dates
before 1970 (epoch) is disabled. This is due to a bug
in the R implementation of POSIX handling of fractional
seconds pre-1970. 10 microsecond granularity is still
functional for all other times. Thanks to Andreas Noack Jensen
for the early bug report.
o new 'tzone' arg in xts constructor and 'tz' in .parseISO8601
allows for future support of non-system TZ dependent indexing
o internal index attribute (numeric) now can have attributes
set (tzone is currently the only one used in xts). These should
remain during all xts operations. Still experimental.
o naCheck has been exposed at the C level for use in packages
"LinkingTo: xts". See ?xtsAPI for more details.
Changes in xts 0.7-0:
o A new NEWS file.
o print.xts now passes ...
o endpoints speedup and bug fix (thanks Ismail Onur Filiz)
o na.omit bug on logical and NaN fixes (thanks Fabrizio Pollastri
and Koert Kuipers)
o fromLast=FALSE for na.locf.xts. Matching to zoo. (thanks
to Sandor Benczik)
o LGLSXP support in leadingNA (R fun naCheck)
o fixed logical and NA 'j' subsetting. Thanks Koert Kuipers.
o as.xts and as.timeSeries fixes for timeSeries changes
o merge and subset now support dimensionless xts (non-standard).
merge segfault fixed when merging all 3 or more zero-width xts objects
and only zero-width objects. Thanks to Koert Kuipers for the report.
o added which.i to [.xts to return i values found via
ISO8601 subset string
o new lines.xts and plot.xts, similar to methods in zoo
o lastof now has sec to 10 microsecond precision, and subsec
arg to append to secs.
o xts() further consistency in NROW/index check
o align.time error checks for positive n= values (thanks Brian Peterson)
o toPeriod updates in C, almost exported. ~600-1200x faster
o new lag_xts in C. Increased speed and index flexibility.
o endpoints 'days' bug fix
o .makeISO8601 function to create ISO8601 compliant string
from xts objects
