dens | R Documentation |
Calculate the density (ddens()
), the distribution (pdens()
),
the quantiles (qdens()
) and generate random
samples (rdens()
) of a kernel density estimate as returned by
fit_angle()
or fit_steplength()
.
rdens(n, density) ddens(x, density) pdens(x, density) qdens(p, density)
n |
integer value, the number of random samples to be
generated with |
density |
a ' |
x |
numeric vector giving the points where the density or distribution function is evaluated. |
p |
numeric vector giving the probabilities where the quantile function is evaluated. |
ddens()
and pdens()
give a vector of length length(x)
containing
the density or distribution function at the corresponding values of x
.
qdens()
gives a vector of length length(p)
containing
the quantiles at the corresponding values of p
. The function rdens()
generates a vector of length n
containing the random samples.
