Estimates of Coefficient of Overlapping for Animal Activity Patterns

Provides functions to fit kernel density functions to data on temporal activity patterns of animals; estimate coefficients of overlapping of densities for two species; and calculate bootstrap estimates of confidence intervals.


CHANGES IN VERSION 0.3.2 (2018-05-03)

  • Fixed getBandWidth to return NA on failure as documented(not NaN or Inf).

  • Vignette updated to mention sunTime and Azevedo et al 2018 paper.

CHANGES IN VERSION 0.3.1 (2018-04-19)

  • Improvements to help page for 'bootCI'.

  • Added 'sunTime' function, maps sunrise and sunset to pi/2 and 3*pi/2.

CHANGES IN VERSION 0.3.0 (2017-05-27)

  • Added 'cores' argument to 'bootEst' to allow parallel processing.

  • Added 'type' argument to 'overlapEst' and 'bootEst'.

  • Included checks for data in plotting functions.

CHANGES IN VERSION 0.2.7 (2017-03-01)

  • Routines in overlap C code now registered.

CHANGES IN VERSION 0.2.6 (2016-02-07)

  • Changes to NAMESPACE to accommodate R 3.3.

CHANGES IN VERSION 0.2.5 (2015-04-16)

  • fixed bug in plotting functions: dots argument not passed to x axis code.

CHANGES IN VERSION 0.2.4 (2014-06-08)

  • plotting functions make full use of the dots argument (...); formal arguments ylim, xlab, ylab, etc, removed.

  • densityPlot and overlapPlot gain an 'extend' argument: if not NULL, the plot is extended by 3 hrs each side of the focal 24-hr period and 'extend' specifies the background colour to use; if NULL, the plot is not extended.

  • overlapPlot gains a rug argument (suggestion of Anand Roopsind)

CHANGES IN VERSION 0.2.3 (2014-05-04)

  • overlapPlot and densityPlot gain argument xcenter, which controls whether the the plot is centered at noon (default) or midnight (wish of Bronwyn Fancourt).

CHANGES IN VERSION 0.2.2 (2014-02-23)

  • overlapPlot gains argument ylim (wish of Jesse Lewis)

  • densityPlot gains arguments ylim, xlab, ylab (wish of Wenhong Xiao)

CHANGES IN VERSION 0.2.0 (2013-08-04)

  • Fixed bug in overlapPlot (reported by Jesse Lewis) and added overlapPlot to examples on 'kerinchi' help page.

  • overlapPlot gains arguments linewidth, xlab and ylab.
