Dear R team, I am a co-author and maintainer of one of R packages distributed by R-forge (gEcon). One of gEcon package users found a strange behaviour of package (R froze for couple of minutes) and reported it to me. I traced the strange behaviour to compiler package. I attach short demonstration of the problem to this mail (demonstration makes use of compiler and tictoc packages only).
In short, the compiler package has problems in compiling large functions - their compilation and execution may take much longer than direct execution of an uncompiled function. Such functions are generated by gEcon package as they describe steady state for economy. I am curious if you are aware of such problems and plan to handle the efficiency issues. On one of the boards I saw that there were efficiency issues in rpart package but they have been resolved. Or would you advise to turn off JIT on package load (package heavily uses such long functions generated whenever a new model is created)? Best regards, Karol Podemski
