spread.grouped {sn} | R Documentation |
Spreading grouped data over intervals
Description
Assuming that counts
represents the frequencies of observations
falling into intervals identified by breaks
, the function returns
a vector of values obtained by uniformly spreading each group of data
over the pertaining interval.
Usage
spread.grouped(breaks, counts, shift = "centre")
Arguments
breaks |
A numeric vector of strictly increasing finite values which identify a set of contiguous intervals on the real line. |
counts |
A vector of non-negative integers representing the number
of observations falling in the intervals specified by |
shift |
a character string which regulates the positioning of the
constructed points within a given interval, with possible values
|
Value
A numeric vector of length sum(counts)
of values
within range(breaks)
.
