In agop, a vector x=(x_1,\dots,x_n)
can be represented by a
step function defined for 0\le y<n
and given by:
\pi(y)=x_{(n-\lfloor y+1\rfloor+1)}
(for type == 'right.continuous'
)
or for 0< y\le n
\pi(y)=x_{(n-\lfloor y\rfloor+1)}
(for type == 'left.continuous'
, the default)
or by a curve interpolating the points (0, x_{(n)})
,
(1, x_{(n)})
, (1, x_{(n-1)})
, (2, x_{(n-1)})
,
..., (n, x_{(1)})
.
Here, x_{(i)}
denotes the
i
-th smallest value in x
.
In bibliometrics, a step function of one of the two above-presented types is called a citation function.
For historical reasons, this function is also available via its alias,
plot.citfun
[but its usage is deprecated].
