想用RHmm建模，数据总是不对，报错，各位大侠，谁来帮我一下？
谢谢！
> raw2<-as.list(subset(raw,select=c('SG.ABS') ))
> raw3<-as.list(subset(raw,select=c('TWP.P3A') ))
> raw_list<-list(raw2,raw3)
> list2 <- HMMFit(raw_list, nStates=3,dis='DISCRETE')
Error in sort.list(y) : 'x' must be atomic for 'sort.list'
Have you called 'sort' on a list?

> raw <- read.csv("data_num_header01.csv",sep=',',header=TRUE)
> raw<-data.frame(raw)
> hdd <- HMMFit(raw, nStates=2)
Error in BaumWelch(paramHMM, obs, paramAlgo) : Non inversible matrix
