将R输出从内存读入矩阵（包点击流）

我使用R包clickstream来估计转移概率

输出如下所示：

Higher-Order Markov Chain (order=2)

现在我所做的是将输出写入文本文件，然后将其作为矩阵读入

sink("mc_output.txt")
mc
sink()


# Lag 1
mydat11 = read.table("mc_output.txt", skip = 6, nrows = 11)
mydat12 = read.table("mc_output.txt", skip = 18, nrows = 11)
mydat13 = read.table("mc_output.txt", skip = 30, nrows = 11)
mydat14 = read.table("mc_output.txt", skip = 42, nrows = 11)
...

当矩阵的维数发生变化时，这种方法很容易出错。这个想法是直接从内存中读取输出。有人有什么聪明的解决办法来实现这一点吗

library(clickstream)
clickstreams <- c("User1,h,c,c,p,c,h,c,p,p,c,p,p,o",
"User2,i,c,i,c,c,c,d",
"User3,h,i,c,i,c,p,c,c,p,c,c,i,d",
"User4,c,c,p,c,d",
"User5,h,c,c,p,p,c,p,p,p,i,p,o",
"User6,i,h,c,c,p,p,c,p,c,d")
csf <- tempfile()
writeLines(clickstreams, csf)
cls <- readClickstreams(csf, header = TRUE)
mc <- fitMarkovChain(cls)

mc

对象也有一些其他插槽：

slotNames(mc)
# [1] "states"                 "order"                  "transitions"            "lambda"                
# [5] "logLikelihood"          "observations"           "start"                  "end"                   
# [9] "transientStates"        "absorbingStates"        "absorbingProbabilities"

正是我要找的！非常感谢你。似乎我找不到基本R的语法command@lukeA你能解释一下这些概率是如何从点击流计算出来的吗？或者你能推荐一些我可以参考的来源吗？请发布一个新问题-我不知道它们是如何计算出来的。
