You've been answered a few days ago when you asked (almost?) the

same question.

Now you've sent it *again* and even twice to the mailing list.

How can we know that you are not just a student who is too

lazy to do his/her homework?

ßõÊ> How I use R-project to solve above question??

it looks like you really try to misuse the "R-project" (namely

its community of volunteers) instead of using R --

for which you need to spend some time learning the language,

functionality, graphics, etc.

do read the posting guide AND some of its links, mentioned at

the end of every R-help message.

Regards,

Martin
