Rstudio内的R找不到rmarkdown包

Question

I am trying to use rmarkdown, within Rstudio (0.98.953) on a PC, for the first time. I have upgraded to the latest versions of R (3.1.1) and R studio. The output from sessionInfo() is provided at the end of this question.

As I understand it rmarkdown should be included within Rstudio. However, when I select to create a markdown document in Rstudio, a dialog box pops up saying additional packages need to be installed. The installation of rmarkdown always then fails, with the following message:

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

I assume this is something to do with using a managed desktop in my place of work. However this is not usually a problem as far fewer restrictions are placed on these machines than is usually the case, and all other packages, software etc tend to work.

I have also tried installing rmarkdown directly from github. Again the installer cannot identify the package rmarkdown itself.

What is likely to be the cause of the error?

Answer 1

Try running this code to get the latest version of the rmarkdown package, which should solve the issue:

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

The issue is that the RStudio IDE looks at a static CRAN snapshot that was taken before the rmarkdown package was updated. For more information, see this link: https://groups.google.com/forum/#!topic/rropen/Kgg8z6FF40I

I wonder if the problem is the space in the path shown for the --library option to your install_github command. I know you say you've installed packages OK before, but my setup sounds just slike yours and rmarkdown works for me. I have RStudio 0.98.953 on Win7, which is a very locked-down corporate machine. I've coerced it into letting me install R packages by setting the env variable R_LIBS to my network home drive. Loading packages is slow, but I have no choice because I cannot write to the C: drive. So, my install_github command has --library="H:/Rlib". Your path has "My Documents" embedded in it. I'm not positive that's the problem, but my github installation of "rstudio/rmarkdown" did succeed. When I do File -> New File -> R Markdown, followed by a press of the "Knit HTML" button, that also completes successfully.

The RStudio github page https://github.com/rstudio/rmarkdown#installation makes it sound like manual installation of rmarkdown in RStudio isn't required, but I did it anyway because I don't always use R through RStudio. Sorry, but I didn't test RStudio by making a new R Markdown file before I manually installed the package.

The RStudio blog post http://blog.rstudio.org/2014/06/18/r-markdown-v2/ says clearly that the rmarkdown package is intended to replace the previous markdown package. The rmarkdown package does not yet appear to be on CRAN, so install_github is necessary.

Answer 3

The best that worked for me is to quit Rstuido, then install rmarkdown package in the base R (not any IDE) and restarting Rstudio.

I am on Windows 10, R 3.3.1, Rstudio Version 0.99.903
