I am a Windows user, just installed the latest R version and Rstudio, and am having a problem with R markdown files.
My Rstudio cannot open the file.. It tries to help me by installing some packages but ends up giving me another error...

I suspect R is having issues with non-ASCII characters in your Windows user name (this is a known issue) but I can't be sure since you are not posting the complete output message.

In case I'm right, you can fix this issue by changing your user folders name or installing into the system level package library instead.

You can change the default library folder by setting your R_LIBS_SITE environmental variable on a .Reviron or .Rprofile file

# In a .Renviron file you can set it by adding this line
R_LIBS_SITE="C:\\Program Files\\R\\R-4.0.3\\library"

This could be related to this issue in RStudio IDE:

Encoding issue that blocks posibility to download R packages (R_LIBS_USER)

bug reproducible

### System details RStudio Edition : Desktop RStudio Version : 1.2.5…033 OS Version : Windows 10 R Version : 3.6.2 ### Steps to reproduce the problem 1) Create a new Windows user, that contains non-ASCII letters in its name, e.g., "BąndymaŠĖĖčž". 2) Log-in to that user. 3) Install R and RStudio. 4) Open RStudio 5) Try to download an "R" package in any way. E.g., ```r install.packages("tidyverse") ``` 6) Follow the print-screens below. Here are the sequence of print screens: ![image](https://user-images.githubusercontent.com/12725868/74753227-7cb4d380-5278-11ea-9514-9cf7f232a61f.png) I pressed "Yes" (i.e., "Taip" in the print-screen), then: ![image](https://user-images.githubusercontent.com/12725868/74753242-850d0e80-5278-11ea-883d-c874e92b0207.png) When "Yes" (i.e., "Taip") is pressed, the result is: ![image](https://user-images.githubusercontent.com/12725868/74753346-ab32ae80-5278-11ea-9eab-b46383f95539.png) No packages are installed. ### Describe the problem in detail Finally, an error message appears displaying that user library cannot be created as non-ASCII symbols are replaced with question marks (?). In R GUI, the result of `Sys.getenv("R_LIBS_USER")` is correct: ![image](https://user-images.githubusercontent.com/12725868/74752008-b97fcb00-5276-11ea-8e6f-be6b2c16dae7.png) In RStudio – encoding issues are visible: ![image](https://user-images.githubusercontent.com/12725868/74752017-bd135200-5276-11ea-8ca1-78d17572e871.png) So it seems, that the issue is related to RStudio. ### Describe the behavior you expected There are 2 things I expect: 1) I expect no encoding issues and the ability to download packages to and use them from the default R user library without changing the value of the environment variable `R_LIBS_USER`. 2) If the encoding issue cannot be solved, a more informative error message must be displayed. E.g., that the value of the environment variable "R_LIBS_USER" should be changed on Windows.

It is at least similar!

What is the result of

Sys.getenv("R_LIBS_USER")
