| circularp {circular} | R Documentation |
`circularp' returns the `circularp' attribute (or `NULL'). `circularp<-' sets the `circularp' attribute.
circularp(x) circularp(x) <- value
x |
a vector or a matrix of circular data. |
value |
a vector of length 6 or a list with six components: type, units, template, modulo, zero and rotation. |
The circularp attribute is a list of six elements: type, units,
template, modulo, zero and rotation; see circular for
their meaning.
Assignments are checked for consistency.
Assigning NULL removes the circularp attribute
and any "circular" class of x.

x <- pi circularp(x) # now NULL circularp(x) <- list(type="angles", units="radians", template="none", modulo="asis", zero=0, rotation="counter") circularp(x) x class(x) <- "circular" # now we set also the class so that print.circular is used x
