RStudio安装程序包和程序包更新都下载然后失败，无法打开文件

Question

Running happily with R 3.4 and RStudio 1.0.143 under Win10 this problem occured bringing project development to a halt. Downloads each occur and are unzipped and then the a presumably first file in the first item gets:

Error in install.packages : cannot open file 'C:/Users/Admin/Documents/R/
win-library/3.4/file30504386b80/rJava/javadoc/resources/background.gif': 
Permission denied

and the prompt returns.

Updating to R version 3.4.1 (2017-06-30), RStudio Version 1.0.153 was to no avail. Using the OS to remolve all R versions and trying again with 3.4.1 did not work. Removing R again and deleting the R directory to refresh the library did not work. My virius software like to tell how helpful it has been and has not, so that issue seems unlikely.

Giving the user full control of the R library did not help.

could package-updates be a tag like install-updates?

Answer 1

It looks there is a problem between Java and rJava.

You should try reinstalling Java using chocolatey package manager ( https://chocolatey.org/ ) and then reinstall rJava package.

I had a similar issue two weeks ago on a windows laptop.

Answer 2

I had this problem for a long time. only in RStudio. Install the package on R and Library it. Go to RStudio and require the package.

It works!
