Make a Distribution Function

Description

turn vectors of a values and their distribution function values into an ecdf. Vectors should be the same length and both increasing.

Usage

makeDist(
  x,
  Fx,
  sorted = FALSE,
  rearrange = FALSE,
  force01 = FALSE,
  method = "constant"
)

Arguments

x	vector of values
Fx	vector of the distribution function values
sorted	boolean indicating whether or not x is already sorted; computation is somewhat faster if already sorted
rearrange	boolean indicating whether or not should monotize distribution function
force01	boolean indicating whether or not to force the values of the distribution function (i.e. Fx) to be between 0 and 1
method	which method to pass to approxfun to approximate the distribution function. Default is "constant"; other possible choice is "linear". "constant" returns a step function, just like an empirical cdf; "linear" linearly interpolates between neighboring points.

Value

ecdf

Examples

y <- rnorm(100)
y <- y[order(y)]
u <- runif(100)
u <- u[order(u)]
F <- makeDist(y, u)
