[R] [FORGED] Mixed Beta Disrubutions

[mesude bayrakci]

Hello,

"Treat everyone with politeness, even those who are rude to you - not
because they are nice, but because you are"

The forum's name is  "R-help",  not "R-help for people who are experts in
statistic and R". Please if you would like to help and just help. If you do
not like the posts (or questions), you simply do not answer.
