1. limma 包安装

在安装基因芯片包limma和biobase时，出现了“Warning in install.packages : package ‘limma’ is not available for this version of R”报错。原因是先得下载bioconductor的包管理器biocmanager，然后即可安装：

> install.packages("limma")
Warning in install.packages :
  package ‘limma’ is not available for this version of R

A version of this package for your version of R might be available elsewhere,
see the ideas at
https://cran.r-project/doc/manuals/r-patched/R-admin.html#Installing-packages

报错，显示这个版本的r没有limma包。查询limma官网，发现:

Installation

To install this package, start R (version “4.0”) and enter:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

BiocManager::install("limma")

运行此代码，成功安装。

2. biobase包安装

BiocManager::install("Biobase")

成功
