Seurat的安裝

Seurat包發布在CRAN官方上。

安裝最新版Seurat

安裝代碼：

install.packages('Seurat')
library(Seurat)

如果出現以下提示，請輸入y

package which is only available in source form, and may need compilation of C/C++/Fortran: 'Seurat'
Do you want to attempt to install these from sources?
y/n:y

安裝較早版本的Seurat

### 安装Seurat3的包
