size | R Documentation |
Compute the size, in either Z or R as appropriate, for each interval in an interval matrix.
## S4 method for signature 'Intervals'
size(x, as = type(x))
## S4 method for signature 'Intervals_full'
size(x, as = type(x))

Should the intervals be thought of as in Z or R? This is usually
determined automatically from the |
For type "Z"
objects, counting measure; for type "R"
objects, Lebesgue measure. For type "Z"
objects, intervals of
form (a,a] and (a,a) are both of length
0.
A numeric vector with length equal to nrow(x)
.
See empty
to identify empty intervals. Note that when
type(x) == "R"
, a size of 0 does not imply that an interval is
empty.
