R语言 sequenza

想要做肿瘤纯度和倍生计算，sequenza包下载后根据给出的参考代码，R语言一直出错：

data.file <- system.file("extdata", "example.seqz.txt.gz", package = "sequenza")

test <- sequenza.extract(data.file, verbose = FALSE)

Error in (function (x, col_types) : unused argument (parallel = 1)

我看到github论坛（https://github.com/issues/recent?issue=sztup%7CscarHRD%7C29）也有类似的问题，但是我试了他们提供个三种方法，依旧失败：

① Installing from GitHub: devtools::install_github("buschlab/sequenza", build_vignettes = FALSE) (suggested by @nr23730).

② Downgrading the iotools package (suggested by @nr23730).

③ Installing the local patch: devtools::install_local("./sequenza-WortJohn-patch-1.zip", force=TRUE, repos=NULL, type="source", dependencies=FALSE) (suggested by @WortJohn).

我甚至到原代码去删除parallel这个参数，但是还是报错！！求助！！！还有什么办法啊，哭了都
