Conversion for Circular Data from one coordinate/units system to another one. For back compatibility, without arguments the function converts data from degrees to radians.

1 2	conversion.circular(x, units = c("radians", "degrees", "hours"), type = NULL, template = NULL, modulo = NULL, zero = NULL, rotation = NULL)

`x`	an object of class `circular`.
`units`	unit of the transformed data.
`type`	type of the transformed data. If `NULL` no action is performed.
`template`	template of the tranformed data. If `NULL` no action is performed.
`modulo`	modulo of the transformed data. If `NULL` no action is performed.
`zero`	zero of the tranformed data. If `NULL` no action is performed.
`rotation`	rotation of the tranformed data. If `NULL` no action is performed.

an object of class circular with the specified unit of measure, modulo, zero and rotation.

deg and rad. If you want to set the properties of an object instead to tranform it, you can use circular or circularp<-.

x <- rvonmises(n=10, mu=circular(0), kappa=9, control.circular=list(units="degrees"))
par(mfcol=c(2, 2))
plot(x)
y <- conversion.circular(x) # only the unit is changed (to radians) and 
####### the data converted.
plot(y)
z <- conversion.circular(x, units="degrees", zero=pi) # only the zero is changed and 
####### the data converted.
plot(z)
w <- conversion.circular(x, zero=pi, rotation="clock") # zero and rotation is 
####### changed and the data converted.
plot(w)
