【问题描述】：
在多次尝试安装 CATS 包 (2013) 和更改 R 版本失败后，我决定使用来自 here 的源代码
我创建了一个包含包中所有 R 函数的单个 R 脚本，我 运行它们，然后我希望这段代码能够运行以在以下代码末尾的示例中绘制功率：
super.cats<-function(RR,MAFmax=0.5,MAFmin=0.005,by=50,rep=1536,SNPs=1E6,ncases,ncontrols,ncases2,ncontrols2,alpha=0.05/SNPs,...){
powerList.O<-c()
powerList.J<-c()
powerList.R<-c()
powerList.F<-c()
power.O<-rep(0,length(RR))
power.F<-rep(0,length(RR))
power.J<-rep(0,length(RR))
power.R<-rep(0,length(RR))
MAF<-exp(seq(log(MAFmin),log(MAFmax),by=(log(MAFmax)-log(MAFmin))/by))
for(nmaf in 1:length(MAF)){
for(tal in 1:length(RR)){
if(power.F[tal]>0.995&power.R[tal]>0.995){
power.O[tal]<-1
power.R[tal]<-1
power.J[tal]<-1
power.F[tal]<-1
break
}
temp<-cats(risk=RR[tal],freq=MAF[nmaf],ncases=ncases,ncontrols=ncontrols,ncases2=ncases2,ncontrols2=ncontrols2,alpha=alpha,pimarkers=rep/SNPs,...)
power.O[tal]<-temp$P.one.study

我曾尝试修改代码，但更改的次数越多，出现的错误就越多。在这一点上，我将不胜感激任何帮助。
从 R 安装软件包时我得到的更新：
