[R] lmomco package and confidence limits?

[Douglas M. Hultstrand]

Hello,

I am using the lmomco package (lmom.ub and pargev) to compute the GEV 
parameters (location, scale, and shape), which are used to estimate 
return values.  I was wondering how/if I can calculate upper and lower 
confidence (CI_u, CI_l) intervals for each return frequency using the 
GEV parameters to fill-in the table below?

Xi (location)   =  35.396
Alpha (scale) =  1.726
Kappa (shape) =  0.397

Year, Return value, CI_u, CL_l
2, 36.0,
5, 37.3,
10, 38.0,
25, 38.5,
50, 38.8,
100, 39.0,

Thank you for your help/suggestions,
Doug
