Question

我正在尝试从randomForestSRC包中运行一些随机生存森林，但遇到了一些我无法理解的错误。我使用的代码是：

rsc = rfsrc(Surv(Length_of_Service_from_Seniority_Date_Including_Partial_Year__CF_,as.numeric(Active))~.,data = x,
            ntree = 10000,nsplit=10,na.action = 'na.omit',importance=T)

我收到以下错误，并且不太明白为什么...：

Error in dimnames(x) <- dn : 
  length of 'dimnames' [2] not equal to array extent
In addition: Warning messages:
1: In doTryCatch(return(expr), name, parentenv, handler) :
  NAs introduced by coercion
2: In matrix(nativeOutput$imputation, nrow = n.miss, byrow = FALSE) :
  data length [335830] is not a sub-multiple or multiple of the number of rows [5694]
