HI I am getting below error when I am trying to load/ install any packages. This happened when installed new version of .
Error in nchar(homeDir) : invalid multibyte string, element 1
In addition: Warning message:
In normalizePath(path.expand(path), winslash, mustWork) : path[1]="C:/Users/my.name/OneDrive - companies name/Documents": The system cannot find the path specified
How to solve this issue?
I think your default library has changed with new R installation. Try this--
.libPaths("Path to your libs")
Then after install and load library again
.libPaths("C:/Program Files/R/R-4.2.1")
Error in nchar(homeDir) : invalid multibyte string, element 1
Same error when I try to change path
you can try to remove special characters (non-ASCII character) from your homeDir or folder or files and then try again.
This means your home directory contains special character. Can you show a complete console output?
R has problems with cloud-synced folders (OneDrive in your case) and non-ASCII characters in your package library path, I recommend you to set your package library in a non-synced folder.
You can change the default library folder by setting your R_LIBS_SITE environmental variable in a .Reviron or .Rprofile file. For example:
# In a .Renviron file you can set it by adding a line like this one with the desired location
R_LIBS_SITE="C:\\Program Files\\R\\R-4.1.2\\library"

Warning message:

this is the output
look for @andresrcs suggestion. He is right.
R is sensitive and you need to be careful with file and folder names. Don't add "space"/"-" or other special character to your folder or file names that you will use in R. So, change your library folder/ or name then try again.
In simple--
Incorrect way--- "C:/Users/my.name/OneDrive -(companies name)l/Documents" because here == "(companies name)", "-" are special character that creating problem in your case 
correct way--- "C:/Users/my_name/OneDrive_companies name_l/Documents" or
"C:/Users/hhyhfh/Documents"
Thank you for all recos.
My lib paths are
.libPaths()
[1] "C:/Users/my.name/R1"
[2] "C:/Program Files/R/R-4.2.1/library"
Warning message:
In normalizePath(path.expand(path), winslash, mustWork) : path[1]="C:/Users/my.name/OneDrive - companies name/Documents": The system cannot find the path specified
why it still giving me this error? also if I want to remove second lib path what should I do , as second one has space in it so I guess it wont work?
It is strange. Are you running your script in R or Rstudio?
Might be. I think you should uninstalled R and Rstudio completely and try again. May be it will help you
