Package: ccgarch

加载了ccgach程序包，运行有关ccgarch说明上（从这上面http://cran-r.c3sl.ufpr.br/下载的）的例子的时候，R报错：[错误: 没有"dcc.sim"这个函数]

示例是：
# Simulating data from the original DCC-GARCH(1,1) process
nobs <- 1000; cut <- 1000
a <- c(0.003, 0.005, 0.001)
A <- diag(c(0.2,0.3,0.15))
B <- diag(c(0.75, 0.6, 0.8))
uncR <- matrix(c(1.0, 0.4, 0.3, 0.4, 1.0, 0.12, 0.3, 0.12, 1.0),3,3)
dcc.para <- c(0.01,0.98)
dcc.data <- dcc.sim(nobs, a, A, B, uncR, dcc.para, model="diagonal")
# Estimating a DCC-GARCH(1,1) model
dcc.results <- dcc.estimation(inia=a, iniA=A, iniB=B, ini.dcc=dcc.para,
dvar=dcc.data$eps, model="diagonal")
# Parameter estimates and their robust standard errors
dcc.results$out
R报错：[错误: 没有"dcc.sim"这个函数]
请教高手解决，十分紧急！

library(ccgarch)
