Create Density Data Frame from Sample — create.density.df • PEcAn.priors

Returns a data frame from stats::density function

Usage

create.density.df(
  samps = NULL,
  zero.bounded = FALSE,
  distribution = NULL,
  n = 1000,
  ...
)

samps: a vector of samples from a distribution
zero.bounded: logical: Restrict density distribution to nonnegative values?
distribution: list with elements distn, parama, paramb, e.g. list('norm', 0, 1)
n: number of points at which to estimate density
...: additional arguments, passed on to stats::density

data frame with x and y = dens(x)

prior.df <- create.density.df(distribution = list('norm',0,1))
plot(prior.df)
samp.df <- create.density.df(samps = rnorm(100))
