Format authors into Authors@R
circular 0.5-0 (2023-09-05)
Added an example to RosediagRad (thanks to Hugo Flávio
Added an example to lm.circular (thanks to Dirk Walther
Drop personList() and citEntry
axis.circular() is no longer an S3 method, just a standalone function
circular 0.4-95 (2022-04-26)
Maintainer change to avoid archiving
Fixed documentation typos
circular 0.4-91
Fixed a bug in heatmap.circular
circular 0.4-8

Added the start.sep argument to plot.circular and points.circular. Also the internal function PointsCircularRad has changed the API
circular 0.4-6
Added function dasytriangular for the density of asymmetric triangular distribution as described in Mardia (1972
In this version two functions are available for evaluating the median (medianCircular which allows for the dispersion parameter and median.circular with only the median reported), however medianCircular is deprecated and it will be removed in the next releases.
Added mean.circular.c to calculate the circular mean in C language
New algorithm for circular median. The implementation is in C language
Added function for Hodges Lehmann estimate of the median for circular and non circular data
Several bugs fixed
circular 0.4-3 (2011-07-23)
Fixed a bug in c.circular function
New functions: watson.williams.test, wallraff.test
Add a summary introduction to the package
Add citation information
Fixed the behaviour of axis.circular for template 'clock12' and 'clock24
Fixed windrose and plot.density.circular for template 'clock12' and 'clock24
Function range.circular use lgamma(x) instead of log(gamma(x
Fixed a bug in density.circular. Now the arguments K and min.k are passed to the internal function
Added functions bw.cv.mse.circular and bw.cv.ml.circular for bandwidth selection using crossvalidation and mse or ml
Added functions sd.default, sd.data.frame, sd.circular (with sd method), angular.variance and angular.deviation.
Added pmixedvonmises function. Now *mixedvonmises functions use argument prop instead of p
Added function quantile.circular
circular 0.4-2 (2011-03-19)
Fixed a bug in rose.diag function. Now the rose.diag function has two new parameters: sub and control.circle
circular 0.4-1 (2011-02-03)
New functions
dgenvonmises, Density for the Generalized von Mises circular distribution.
djonespewsey, Density for the Jones and Pewsey circular distribution
dkatojones, Density for the Kato and Jones distribution
dcarthwrite, Density for the Carthwrite's power-of-cosine distribution
Fixed a bug in density.circular
rose.diag function has new parameters and better control of the colors. Now it use polygon instead of lines.default and it draws edges of sectors as arcs.
Fixed bug on qvonmises and its documentation
Fixed bug on qwrappednormal
Fixed bug on arrows.circular
Now range.circular do not retain the rotation attributes. Always return a counter rotation angle
circular 0.4 (2010-08-01)
Refixed range.circular
circular 0.3-9
Fixed bug #729 on watson.two.test function
Fixed bug #69 small bug in rose.diag of R package "circular", 0.3-8 and the same problem in the points.circular and plot.circular
Fixed bug #104 bug in rvonmises, 0.3-8. Now, when kappa is zero, random deviates are generated according to the Circular Uniform Distribution
Use patches #193 to fix for plotting many arrows with one call to arrows.circular
Add the argument control.circle to pass parameters to the internal function that draws the circle in plot.circular, curve.circular, plot.circular.function, plot.density.circular. A function, circle.control, is introduced to set those parameters. This is used instead of the proposed patches #194 The CirclePlotRad() function can accept "..." but it isn't currently passed
Add the argument sub, and change the default of main to NULL in the above functions
Internal functions PointsCircularRad and RosediagRad use the hist function to construct intervals in stack=TRUE
Add units "hours" for data expressed in hours (minutes and seconds must be expressed in decimals
Add template "clock12" and "clock24" to plot data which are time.
Add dist.circular function
Add heatmap.circular function
Add medianCircular function
Add offset argument to the lines.circular, lines.density.circular, plot.density.circular functions
Add shrink argument to the lines.circular function
Function lines.circular return x and y in the invisible object
Fixed the name of the help page for the circular function
circular 0.3-8 (2007-08-25)
Now unique.circular calls unique.default instead of the internal function. print.rao.spacing.test loads locally the dataset rao.table
circular 0.3-7 (2007-08-14)
Fix a problem in the api of unique.circular function, fix the documentation of summary.circular and [.circular
circular 0.3-6 (2006-08-28)
Changed long declaration into int in circular/src/rvonmises.c file
circular 0.3-5 (2006-08-24)
Rewrite most of the functions. Add functions c.circular, unique.circular, curve.circular, plot.function.circular, lines.circular. Add arguments to conversion.circular and change its behavior. Add pwrappednormal, qwrappednormal (experimental versions). Add new features to r,d,p,q functions (now mu must be specifies using a circular object
Almost all the functions use control.circular argument in order to specify the attribute of the resulting object. The rvonmises function uses a C code from Harry Southworth
circular 0.3-4 (2006-02-13)
Add an argument to windrose, rewrite small part of it. Fix typos in kuiper.test.Rd, extract.Rd and lm.circular.Rd. Now, var.default definition in var.circular.R point to stats::var and not to base::var
circular 0.3-3 (2005-12-07)
Add NAMESPACE file. Functions now use atan2 instead of atan when two arguments. summary.circular is fixed
circular 0.3-2 (2005-05-05)
Remove direct call to x11() in man pages
circular 0.3-1 (2005-05-03)
Remove the alias density and density.default and the corresponding documentation. Fix a problem in the documentation of lsfit.circle. Change MSE and SSE to MS and SS in aov.circular
circular 0.3 (2005-04-27)
All the functions handle NA values. Most of them by removing NA (without ask). When more than one variable is needed only complete cases are considered
Added functions: aov.circular, equal.kappa.test, lsfit.circle
Modified the function lm.circular so that now circular-circular and circular-linear regression are available
circular 0.2
circular 0.1 (2004-05-25)
