我正在尝试为 R 安装 data.table 库,但我无法让它工作。我尝试同时使用 CRAN 和 Bioconductor,但我一直收到一个错误,即该包不适用于 R 3.2.2:
> biocLite('data.table')
BioC_mirror: http://bioconductor.org
Using Bioconductor version 3.1 (BiocInstaller 1.18.4), R version 3.2.2.
Installing package(s) ‘data.table’

> install.packages("data.table")
Warning: unable to access index for repository

我真的不知道该怎么做......对R来说很新。
