我是linux的新手并且正在努力为R安装插入符号。我在插入符号安装过程中收到以下错误。
configure: Need to download and build NLopt
trying URL 'http://ab-initio.mit.edu/nlopt/nlopt-2.4.2.tar.gz'
Error in download.file(url = "http://ab-initio.mit.edu/nlopt/nlopt-2.4.2.tar.gz", :

Warning message:

configure: Starting to install library to /tmp/RtmpIT5jNR/R.INSTALL17d113d7c2a/nloptr/nlopt-2.4.2
./configure: line 3325: cd: nlopt-2.4.2: No such file or directory
此后停止，浮动，然后我必须崩溃R来修复它。我已经通过nlopt网站进行了搜索，并根据错误尝试手动安装到R中。我有实际的tar文件，我把它放入Rstudios包文件，然后经历了安装它的过程。但是，这似乎根本不起作用。我猜测有什么特定的R需要完成安装吗？
注意我已尝试通过install.packages安装nlopt，并发生同样的错误。有任何想法吗？

我重新认识我没有使用最新版本的R而且不幸的是无法升级。然而，Caret包装信息声称它应该适用于大于R（> = 2.1），晶格（＆gt; = 0.2）和ggplot2的任何东西。符合所有标准。
