Cannot install github package, lazy error

[swisner]

Hi I'm trying to download a github package and I keep getting this error. I'm not sure how to fix.

devtools::install_github("ethanplunkett/rasterPrep")

"setwd('C:/Users/SARA'S"

R has problems with non-ASCII characters and empty spaces on Windows user names, either change your username to something safer or install into the system level package library instead.

You can change the defaul library by setting your R_LIBS_SITE environmental variable on a .Reviron or .Rprofile file, for example.

# In .Renviron file you can set it by adding this line
R_LIBS_SITE="C:\\Program Files\\R\\R-4.0.2\\library"
