whichInterval: From a set of intervals, find which interval values belong to
Description
Returns which interval (if any) each number in a vector belongs to, given a set of
user-defined intervals. Intervals can be specified using either two-column matrices or
Intervals objects from the intervals package.
Usage
whichInterval(x, Intv)
which_interval(x, Intv)
Arguments
x
A vector of numeric values
Intv
A two-column matrix or an object of class Intervals
Value
For each value in x: if x[i] is in the set of intervals, the index of the corresponding
interval(s), NA if no interval contains x[i]
# NOT RUN {start <- c(0, 1, 2)
end <- c(.5, 1.3, 3)
intv <- cbind(start, end) # The first interval is 0-0.5, second is 1-1.3, etc.whichInterval(seq(0, 3, l = 10), intv)
# }
