Details<br />
Value<br />
A time series can either be irregular (unequally spaced), strictly regular (equally spaced) or have an<br />
underlying regularity, i.e., be created from a regular series by omitting some observations. Here,<br />
the latter property is called regular. Consequently, regularity follows from strict regularity but not<br />
vice versa.<br />
is.regular is a generic function for checking regularity (default) or strict regularity. Currently, it<br />
has methods for "ts" objects (which are always strictly regular), "zooreg" objects (which are at<br />
least regular), "zoo" objects (which can be either irregular, regular or even strictly regular) and a<br />
default method. The latter coerces x to "zoo" before checking its regularity.<br />
See Also<br />
A logical is returned indicating whether x is (strictly) regular.<br />
zooreg, zoo<br />
