rmultinom(n=1,size=500,prob=c(0.3,0.5,0.2)) to get n samples each of size 500 just use the "n=" argument.

The probability of x, y and z is respectively is 0.3, 0.5, 0.2. I wan to simulate a new same size population based ratio of x, y and z, how can I get and assess the number of x, y and z. ? luan Key Laboratory for Sustainable Utilization of Marine Fisheries Resources, Ministry of Agriculture ,Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, Qingdao 266071,China __________________________________________________ 雅虎免费G邮箱－中国第一绝无垃圾邮件骚扰超大邮箱 ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
