Functions returned by functions. Note that you can name your functions whatever you like. (In the vignette I've named them f, F and F.inv). Also note that you don't call these functions, rather call epdfuv(), ecdfuv(), etc and then call the functions that are returned.
# NOT RUN {#construct an empirical quantile function and then evaluate it#(compute the 0.25 quantile)x = rnorm (30, 4) ^ 2ecdfuv.f.inverse = ecdfuv.inverse (x)
ecdfuv.f.inverse (0.25)
