#############

changes in version 1.1.8 (2008-03-13)

* added grizzly bear population counts for count-based PVAs

* added extCDF function for extinction time cdfs.  This function is
  called by countCDFxt and was previously hidden in that function.

* added plot optioin to countCDFxt and set default value for tq
  option, which is usually equal to number of tranistions (nt) for
  regularly censused populations.

#############

changes in version 1.1.7 (2008-02-21)

* added Calathea to LTRE example with plot, year, and interaction
  effects

* added s3 method for function mean.list to get the mean matrix from a list of
  matrices.  

#############

changes in version 1.1.6 (2008-01-14)

* changed ltre to LTRE

* added plots to vitalsens example

#############

changes in version 1.1.5 (2008-01-05)

* added ltre function for fixed LTRE.  A random design is included in the
  example

* added Calathea dataset for tropical understory herb in Horvitz and
  Schemske (1995)

* fixed damping ratio in eigen.analysis.  Now the function finds the
  second largest modulus and not just modulus of the second eigenvalue ( in case
  of eigenvalues with equal magnitudes in imprimitive matrices).
  Also, added which.max to find dominant eigenvalue instead of
   which(Re(ev$values)==max(Re(ev$values))) which may return two or
  more indexes in some cases

#############

changes in version 1.1.4 (2007-11-13)

* fixed error in image plot on teasel example after loading to CRAN

#############

changes in version 1.1.3 (2007-11-13)

* added function vitalsens for vital rate sensitivities and
  elasticities 

* added matplots to teasel example

* changed name of lambda to lambda1 in eigen.analysis output to match
  package demogR (in case demogR is loaded after popbio, then
  functions using eigen.analysis should still work with some
  exceptions, eg, if matrix is singular)

#############

changes in version 1.1.2 (2007-09-13)

* fixed undefined nyrs variable in varEst

* added checks to head2 function to work with matrix or dataframe
  input only 

* removed extra brackets, foreign language encodings (Akcakaya) in .Rd
  files requested by JSS editors

#############

changes in version 1.1.1 (2007-08-25) 

* added pfister.plot to create log-log plots of variance
  vs. sensitivity and CV vs. elasticity

* added more plotting examples (fig 9.3, 9.4, 9.11) from chap 9 in
  Caswell to teasel and tortoise datasets

* added age-specific survival and fertility curves (fig 5.1 and 5.2)
  to whale dataset

* corrected errors in hudcorr matrices and vitalsim function suggested
  by Doak in email dated 8/4/07.

* added plot based on fig 8.3 to vitalsim function and code (not run)
  to simulate no correlations or only within-year correlations

* changed colors in stage.vector.plot to rainbow(8)

* added column names to boot.transitions (vector and matrix output,
  e.g., a11, a21, a31 a12, ...) and pop.projection output 
 
* changed stage.vector.plot examples to project matrix in example 2.1
  in Caswell and create figure 2.3.

###################

changes in version 1.1  (2007-07-28)

* added new functions and datasets contirubted by Patrick Nantel

* added default row and column names (if missing) to stage.vector.plot,
  checks for matrix with 2 or more stages, and repeats
  colors if necessary

* now checking if matrix is singular in eigen.analysis.  If matrix is
  singular, NA values are used instead of exiting with a warning.
  This is useful for bootstrapping that may create singular matrices

* added print statements on long loops used in all three  stochastic
  growth  functions to track progress
 
* now rounding stages first in vector before checking extinction probability
  in stoch.quasi.ext.  Now if vector is (.3,.4,.4) and ext prob=1 then
  rounding stages sets n=0.
