./math/R-zoo, S3 Infrastructure for Regular and Irregular Time Series

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.8.0, Package name: R-zoo-1.8.0, Maintainer: pkgsrc-users

An S3 class with methods for totally ordered indexed observations. It
is particularly aimed at irregular time series of numeric
vectors/matrices and factors. Zoo's key design goals are independence
of a particular index/date/time class and consistency with ts and base
R by providing methods to extend standard generics.

Update to 1.8.0

Upstream changes:
Changes in Version 1.8-0

  o zoo() and zooreg() gained a calendar = getOption("zoo.calendar", TRUE)
    argument so that, by default, yearqtr and yearmon are used as the time
    index for regular zoo series with frequency 4 and 12, respectively. With
    calendar = FALSE the behavior from previous versions with plain
    unclassed time indexes can be obtained. Set options(zoo.calendar = FALSE)
    to always retain the old behavior.

  o na.locf() is made faster by using a diff()-based solution rather than
    cumsum() (suggested by Ruben Arslan). Also, the workhorse function
    na.locf0() underlying the default na.locf() method is now exported
    in the user interface as it is faster (but also supports less options).

  o Better support of vector-valued 'split' arguments in read.zoo().

  o Special-cased rollmax(..., k = 1) to return the input coredata().

  o as.character() for "yearqtr" objects did not process NA elements \ 
correctly.

Update to 1.7.14

Upstream changes:
Changes in Version 1.7-14

  o Several convenience interfaces to read.zoo() have been added:
    read.table.zoo(), read.csv.zoo(), read.csv2.zoo(), read.delim.zoo(),
    read.delim2.zoo(). All of these first call the corresponding read.*()
    function to read the data from a text file (with the respective default
    settings) and subsequently call read.zoo() to turn the data into
    a zoo series.

  o na.approx.default() did not properly process the "maxgap" argument
    if y did not contain any NAs but NAs were only created implicitly
    by xout being different from x (pointed out by Stefan Metzger).
    A suitable fix has been added that merges x and xout first.

  o aggregate.zoo() and rollapply.zoo() gained the argument coredata=TRUE
    which can control whether only the coredata is passed to each subset
    (previous behavior) or the full zoo series.

  o The "its" package has been archived on CRAN and hence removed from
    the list of zoo's suggested packages. However, various methods for
    objects of class "its" continue to be available in zoo in case someone
    still uses the legacy code.

Update to 1.7.13

Upstream changes:
Changes in Version 1.7-13

  o The window() method erroneously dropped the dimension in case of
    1-column zoo series. Fixed now.

  o Bug fix in NA handling of rollmax() pointed out by Cory Fletcher.

  o A few as.yearmon/as.yearqtr methods were not registered in
    the NAMESPACE but are now.

  o If there are less then two non-NAs in na.approx() then approx()
    cannot be applied. Instead of throwing an error (as up to version
    1.7-12) simply no NAs are replaced now.

  o Bug fix for lag(z, k = k, na.pad = TRUE) which ignored na.pad = TRUE
    if 'k' was a vector of lags.

Update to 1.7.12

Upstream changes:
Changes in Version 1.7-12

  o read.zoo with a data.frame argument now defaults to FUN = identity
    if the index.column is not character or factor.  See ?read.zoo for
    additional details.

  o Added a dim<- method that checks whether the new dimension value
    appears to be ok and then calls the default.

  o The index<- and time<- methods now enforce that the new time index
    is actually correctly ordered (suggested by Joshua Ulrich).

  o read.zoo() heuristic improved so that POSIXct rather than Date is
    detected in cases like: read.zoo(text = "2010-01-01 12:05:03 88.1",
    index = 1:2).

  o The fortify() method now has a col.names argument that allows to set
    (some of) the column names of the resulting data.frame.

  o Various small bug fixes and enhancements.

Update LICENSE

Upstream changes:
Changes in Version 1.7-11

  o Extended the license from "GPL-2" to "GPL-2 | GPL-3".

  o Avoid duplications in Suggests/Imports/Depends in the package's
    DESCRIPTION. Use only :: instead of ::: to access certain functions
    from other namespaces.

  o Added as.list() methods for yearmon/yearqtr.

  o Added workaround in Ops.zoo if first argument is not a zoo series
    (prompted by Josh Ulrich).

  o The transform() method for zoo series now does what method for
    data.frame does (instead of just calling it) in order to get
    non-standard evaluation.
