为R安装data.table时出现问题 [英] Problems installing data.table for R

问题描述

我正在尝试为R安装data.table库，但无法正常工作.我尝试同时使用CRAN和Bioconductor，但仍然收到错误消息，该软件包不适用于R 3.2.2:

I'm trying to install data.table library for R, but I can't get it to work.I've tried using both CRAN and Bioconductor but I keep getting an error that the package is not available for 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.

我真的不知道该怎么办...对R来说是个新手.

I really have no clue what to do...very new to R.

推荐答案

我在Windows 8上尝试使用RStudio(V 0.99.903)和R(最新版本3.3.1)安装data.table时遇到了类似的问题.发出命令install.packages('data.table')，但失败.对我有用的是直接用R运行install.packages.它已正确安装.

I faced a similar issue trying to install data.table using RStudio (V 0.99.903) and R (latest version 3.3.1) on windows 8. I issued the command install.packages('data.table') but it failed. What worked for me was running the install.packages with R directly. It got installed properly.
