我使用apt get來安裝它，現在它說3.2.2 - 這是一個違規的版本。我如何降級到3.1.1？如何在Ubuntu上將R版本3.2.2降級到版本3.1.1

更新：

install.packages(c("batch", "bitops", "boot", "caTools", "data.table", "doMC", "doSNOW", "ggplot2", "glmnet", "lda", "Matrix", "matrixStats", "moments", "plotrix", "psych", "reshape", "topicmodels", "wordcloud", "methods"), dependencies=TRUE)

「已知問題：package'methods'不適用於R 3.2.1版，在這種情況下，請將R降級到版本3.1.1」 - 我現在從頭開始全新安裝R。 – user5331677

但'方法'是一個默認包，隨R安裝而來。 – 2015-10-07 06:14:54

所以我最近遇到了同樣的問題。這裏有一個解決方案：

刪除當前安裝的 - [R版本，

sudo apt-get remove r-base-core 
sudo apt-get autoremove

查找你需要的版本，
```
apt-cache showpkg r-base 
```

它看起來像以下：

Package: r-base 
Versions: 
3.2.2-1precise0  (/var/lib/apt/lists/cran.rstudio.com_bin_linux_ubuntu_precise_Packages) 
Description Language: 
      File:  /var/lib/apt/lists/cran.rstudio.com_bin_linux_ubuntu_precise_Packages 
       MD5: 5787ca79ed716232c4cc2087ed9b425b

之後，查找所需版本並安裝它。但是，在R基本將再次拋出錯誤，安裝所以才執行：

sudo apt-get install r-base-core=3.1.1-1precise0

您應該指定''精確'指的是Ubuntu安裝。例如，對我來說，這是'可靠的'。 – MERose
