mclapply可以使用CompressedRleList嗎？

mclapply可以使用CompressedRleList嗎？mclapply可以使用CompressedRleList嗎？

例如，我有雪茄（A）的載體，以及cigarToRleList返回CompressedRleList因爲向量：

a = c("44M","44M","9S35M","44M","40M4S") 
b = cigarToRleList(a)

如果我嘗試的b mclapply運行我得到這個錯誤：

mclapply(b,function(x) class(x)) 
Error in as.list.default(X) : 
    no method for coercing this S4 class to a vector

強迫b到A列表似乎並沒有幫助，因爲這名單是長度爲1：

mclapply(list(b),function(x) class(x)) 
[[1]] 
[1] "CompressedRleList" 
attr(,"package") 
[1] "IRanges"

任何想法如何讓mclapply與CompressedRleList結構一起工作？

這是一個Bioconductor問題，所以應該寄給Bioconductor郵件列表。過去有問題，所以請提供sessionInfo()的輸出;我相信與現在的Bioc一樣，它與
