Rstudio内的R找不到rmarkdown包

Question

我试图在PC上的Rstudio(0.98.953)中使用rmarkdown,这是第一次.我已升级到R(3.1.1)和R studio的最新版本.sessionInfo()的输出在此问题的末尾提供.

据我所知,rmarkdown应该包含在Rstudio中.但是,当我选择在Rstudio中创建markdown文档时,会弹出一个对话框,说明需要安装其他软件包.rmarkdown的安装总是失败,并显示以下消息:

Installing package into '\\cfsk18.campus.gla.ac.uk/SSD_Home_Data_X/jm383x/My        Documents/R/win-library/3.1'

我认为这与在我工作的地方使用托管桌面有关.然而,这通常不是问题,因为对这些机器的限制远少于通常的情况,并且所有其他软件包,软件等往往起作用.

我也试过直接从github安装rmarkdown.安装程序再次无法识别软件包rmarkdown本身.

可能是错误的原因是什么？

Answer 1

尝试运行此代码以获取最新版本的rmarkdown软件包,这应该可以解决问题:

install.packages("rmarkdown", repos = "https://cran.revolutionanalytics.com")

问题是RStudio IDE会查看在更新rmarkdown软件包之前拍摄的静态CRAN快照.有关详情,请访问以下链接:https://groups.google.com/forum/#!topic/rropen/Kgg8z6FF40I

我想知道问题是否出在 install_github 命令的 --library 选项显示的路径中的空间。我知道你说你之前已经安装了软件包，但我的设置听起来和你的很像，而且 rmarkdown 对我有用。我在 Win7 上安装了 RStudio 0.98.953，这是一台非常锁定的企业计算机。我通过将环境变量 R_LIBS 设置为我的网络主驱动器来强制它让我安装 R 软件包。加载包很慢，但我别无选择，因为我无法写入C:驱动器。所以，我的 install_github 命令有 --library="H:/Rlib"。您的路径中嵌入了“我的文档”。我不确定这就是问题所在，但我的 github 安装“rstudio/rmarkdown”确实成功了。当我执行“文件”->“新建文件”->“R Markdown”，然后按“Knit HTML”按钮时，也成功完成。

RStudio github 页面https://github.com/rstudio/rmarkdown#installation听起来好像不需要在 RStudio 中手动安装 rmarkdown，但我还是这么做了，因为我并不总是通过 RStudio 使用 R。抱歉，在手动安装软件包之前，我没有通过制作新的 R Markdown 文件来测试 RStudio。

RStudio 博客文章http://blog.rstudio.org/2014/06/18/r-markdown-v2/明确表示，rmarkdown 包旨在替换以前的 markdown 包。rmarkdown 包似乎还没有出现在 CRAN 上，所以 install_github 是必要的。
