我在Ubuntu机器上的R 3.0.2(2013-09-25)软件包安装过程中遇到此问题:

install.packages("randomForest")
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning in install.packages :
  'lib = "/usr/local/lib/R/site-library"' is not writable

怎么解决？

在Ubuntu 14.04中使用Rstudio 3.0.2版安装rgl，maps软件包时出现错误

install.packages("rgl")
install.packages("maps")

错误：

Package LibPath Version Priority Depends Imports LinkingTo Suggests Enhances License License_is_FOSS License_restricts_use OS_type Archs MD5sum NeedsCompilation Built

怎么解决呢？
