I want to write a R- function to make a CDF plot of all realizations 
(sim1, sim2, sim3........) with CDF of observed data (suppose zinc of 
muse data). Help will be appreciated
Thanks
Zia

library(gstat)

data(meuse)

data(meuse.grid)

coordinates(meuse) = ~x + y

coordinates(meuse.grid) = ~x + y

lzn.vgm <- variogram(log(zinc) ~ 1, meuse)

lzn.fit <- fit.variogram(lzn.vgm, model = vgm(1, "Sph", 900, 1))

lzn.sim <- krige(log(zinc) ~ 1, meuse, meuse.grid, v.fit, nsim = 6, nmax 
= 40)

/lzn.sim at data <- exp(lzn.sim at data)/
