My example:
> x <- c(0, 1, 2, 3, 4, 5)
> y <- c(6, 4, 1, 8, 7, 8)
# zyp.sen and confint.zyp function
> slope <- zyp.sen(y~x)
> slope$coef
Intercept x
4.5000000 0.6666667
> ci_99 <- confint.zyp(slope, level=0.99)
> ci_99
0.005 0.995
Intercept -2.071288 10.07129
x -3.000000 3.00000
> ci_95 <- confint.zyp(slope, level=0.95)
> ci_95
0.025 0.975
Intercept -0.6196794 8.619679
x -2.5000000 2.333333
