r - What can I do when I found an error in the function? -

currently i'm studying applied linear regression models, kutner.

i used library(alsm), during working on example in chapter 4.3 computer, found ci.reg function has error in calculating simultaneous prediction intervals new observations.

and figured out in

else if (match.arg(type) == "s") {     s <- spred     z <- s } 

part, 2 rows should interchanged.

i have personal library in github, can avoid same problems on, can more in order notify function has kind of matter in part? found alsm library in github well, can't comment there...

thank you.
