Error: install.packages failed to lock directory
在使用bioconductor安装一些包的时候，比如我安装GEOquery时，会有
Error in unpackPkgZip(foundpkgs[okp, 2L], foundpkgs[okp, 1L], lib, libs_only, :
ERROR: failed to lock directory ‘C:\Program Files\R\R-3.6.1\library’ for modifying
如下：
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("GEOquery")
> BiocManager::install("GEOquery")
Bioconductor version 3.10 (BiocManager 1.30.10), R 3.6.1 (2019-07-05)

Try removing ‘C:\Program Files\R\R-3.6.1\library/00LOCK’
解决办法：找到‘C:\Program Files\R\R-3.6.1\library/00LOCK’ 将 00LOCK文件夹删掉，重新安装就可以了
