Attributes of Random Variables

rvattr

rvattr(x, attrib = NULL)

rvattr(x, attrib = NULL, by.name = FALSE) <- value

Arguments

x

an object

attrib

name of the attribute

by.name

logical; attempt matching of attributes by name?

value

vector of values to set; can be a list or an atomic vector

Details

If by.name=TRUE, the values within the list value are matched by their name (e.g. `theta[1]') if possible. Matching by NA or the empty string in a name is not possible.

Otherwise, the list is matched by position; in this case, the length of value must be equal to that of x.
