r - jsonlite for R 在尝试安装时出错

Question

从哪里获得 jsonlite？显然它从 CRAN 中丢失了？

> install.packages('jsonlite')

给出：

Installing package into ‘C:/Users/cbusch/Documents/R/win-library/3.2’
(as ‘lib’ is unspecified)
trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.2/jsonlite_0.9.20.zip'
Warning in install.packages :
  cannot open URL 'https://cran.rstudio.com/bin/windows/contrib/3.2/jsonlite_0.9.20.zip': HTTP status was '404 Not Found'
Error in download.file(url, destfile, method, mode = "wb", ...) : 
  cannot open URL 'https://cran.rstudio.com/bin/windows/contrib/3.2/jsonlite_0.9.20.zip'
Warning in install.packages :
  download of package ‘jsonlite’ failed

有什么建议么？

就像@user5249203 说的：

install.packages('jsonlite', dependencies=TRUE, repos='http://cran.rstudio.com/')
