我正在尝试在R版本3.5.1中安装bioconductor，并且在运行biocLite()时遇到以下问题
Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
cannot open the connection
In addition: Warning messages:
1: In download.file(url, destfile, method, mode = "wb", ...) :
downloaded length 3059712 != reported length 4618652
2: In unzip(zipname, exdir = dest) : error 1 in extracting from zip file
3: In read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
cannot open compressed file 'survival/DESCRIPTION', probable reason 'No such file or directory'
我该如何解决此问题，我已经尝试过以管理员身份运行Rstudio，但仍然没有成功。
谢谢， 桑托什
