Changes in version 0.24                         

  - Bugfix: When using splines, generateData threw an error due to the
    variable not being within the dataset.
  - Bugfix: fixed a bug in print.contrast pointed out by Mads Jeppe
    Tarp-Johansen

                        Changes in version 0.23                         

  - Package reorganized to use roxygen2, markdown, testthat, code
    coverage, continuous testing, and other features.

  - The degrees of freedom for lme models were changed (again).
    Previously, it would make this determination from the number of data
    points, fixed effect parameters, and random effect parameters. Now
    it follows what the doBy package does, using internal data from lme
    objects and takes the smallest possible degrees of freedom if
    variables involved in the the contrast have variable df. The
    previous method for counting df did not align with the results
    inside of the lee objects for simple cases.

                  Changes in version 0.22 (2020-03-19)                  

  - Maintainer email was changed

  - A typo was fixed in the vignette

                  Changes in version 0.19 (2013-11-16)                  

  - For lme models, Thorn Thaler found a bug in some models where the
    calculation of model degrees of freedom could not be determined and
    proposed a fix.

                  Changes in version 0.18 (2013-05-24)                  

  - If the sandwich estimate failed, the traditional covariance
    estimator is used instead.

  - Moved to a real NEWS file format.

  - A bug was fixed (spotted by Thorn Thaler) where normal (not t)
    distributions were being used with lme and gls models to calculate
    confidence intervals.

                  Changes in version 0.17 (2011-12-24)                  

  - Fixed links in man page to point to rms instead of Design

                  Changes in version 0.16 (2011-11-25)                  

  - The package was updated to work with the rms package instead of the
    Design package.

  - A bug was fixed for generalized linear models with no degrees of
    freedom, such as log-linear models.

  - The vignette was slightly reformatted.

                  Changes in version 0.14 (2011-08-01)                  

  - An error check was added for lme models that will fail if the
    covariance matrix of the variance-covariance coefficients has issues
    (since lme counts the number of random effects when calculating
    degrees of freedom).

  - With lme, this problem is signaled by lmeObject$apVar being a
    character string (eg. "Non-positive definite approximate
    variance-covariance")

                  Changes in version 0.13 (2010-02-15)                  

  - Fixed typo in manual

                  Changes in version 0.12 (2009-10-19)                  

  - Added log fold-change transformation

                        Changes in version 0.11                         

  - Cleaned up the package vignette a little

                  Changes in version 0.10 (2009-07-18)                  

  - Added specific namespace calls to nlme so that lme4 methods do not
    interfere.
