无法采用上述三种方法为R的旧版本（v3.3.3）手动安装旧软件包（VGAM）以便在平台上工作：x86_64-apple-darwin13.4.0（64位）
我试图从中得出的关于该主题的先前主题：
Manually Downloading and Installing Packages in R
"installation of package 'FILE_PATH' had non-zero exit status" in R
我正在运行Mac OS 10.9.5，因此必须运行R v3.3.3。因此，我无法加载VGAM软件包的当前版本，因此我一直在尝试并无法通过使用下面的代码来安装VGAM软件包的先前版本，但是所有这三种尝试均导致退出状态为非零。看来gfortran存在问题？不知道这是什么或做什么。
install.packages('VGAM_1.0-2.tar.gz', lib = "/Users/benny/Google Drive/SEDGWICK PROJECT GRANIVORES/R", repos = NULL, dependencies = TRUE)
download.file('https://cran.r-project.org/src/contrib/Archive/VGAM/VGAM_1.0-0.tar.gz',
f <- tempfile())
untar(f, exdir=tempdir())
file.copy(file.path(tempdir(), '.RData'), 'VGAM.RData')
# the above copies the .RData file to a file called VGAM.RData in your current
# working directory.
load('VGAM.RData')
download.file('https://cran.r-project.org/src/contrib/Archive/VGAM/VGAM_1.0-0.tar.gz',
f <- tempfile())
untar(f, exdir=tempdir())
load(file.path(tempdir(), '.RData'))
我希望成功安装VGAM软件包，但是对于每个代码块，我分别收到以下错误消息：
>* installing *source* package ‘VGAM’ ...
** package ‘VGAM’ successfully unpacked and MD5 sums checked
** libs

Warning in install.packages :

对于第二个块/尝试，file.copy（）方法仅产生“ FALSE”输出，并且似乎不能像我想要的那样正确地创建“ VGAM.RData”文件：
[1] FALSE

Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection
第三个块/尝试返回以下错误：
