Ming, You have received a number of excellent replies to your question and should really consider them. Here is another point--really extending a Bill Venables comment:
"If people were out to push dodgy software, this is not the way they'd go about it." Definitely! Look at the requirements for submitting a package to R. While the required documentation and uniform approach mandated do not automatically equate to V&V'ed code it is a strong indication of commitment of the R core and contributing communities. The imposition of these standards by the core team and the time committed to the project vis-a-vis development, the help list, etc. speaks volumes about the quality of R. Rest assured such commitment is not the norm. That being said, I do respectfully disagree with Dr. Rossini in one minor detail ;O). It is not 'extremely paranoid' to re-code in another language and definitely not so to do hand calculations! Murphy's Law is relentless in all matters! If you are like most of us (all of us?) you will find errors in your own coding and maybe rarely an R bug. BTW, since you are starting out in R...voraciously read the documentation, helplist, newletter, and other free and commercial material on R, work thru the examples relevant to you area of endeavor, read more, code more, read more, code more, read more, code more.... The facility with R that you gain as a result will reward you multifold down the road. Best regards, Michael Grant P.S. Whenever you upgrade R, read the CHANGES, NEWS files, etc. R does evolve--even the core--although it is very controlled and managed. (You will learn of bugfixes there too.) --- [EMAIL PROTECTED] wrote: > Dear all, > I am beginner using R.
