Dears, how could I convert an existing package to be able to modify it? Let s say, if I want to change the way how the results of the package are display (to see the oroginal code of the code). Thanks [[alternative HTML version deleted]]

...the example below. 1) How could I force the algorithm to generate knots in hinge function only with values < 90 for e.g. variable doy? 2) Is it possible to restrict the algorithm to generate maximum number of terms per a selected variable e.g. humidity? e.g. 1 term instead of 2?

...^theta-1) / (-((theta*(1 - log(t))^(-1 + theta))/t)) I am always meeting some difficulies to random generate data. Or to make a program code to count inverse function of my phi which should help in the algorithm to generate data. It would be grateful if you could help me. Thanks a lot. -- Mgr.
