I try to install "poibin" package however I failed. Then, I have tried any other package however R returns errors.
install.packages("poibin", lib = "C:/Users/Z�lal/Documents/R/win-library/4.0")
Warning in install.packages :
'lib = "C:/Users/Z<U+FFFD>lal/Documents/R/win-library/4.0"' is not writable
trying URL 'https://cran.rstudio.com/bin/windows/contrib/4.0/poibin_1.5.zip'
Content type 'application/zip' length 50056 bytes (48 KB)

package ‘poibin’ successfully unpacked and MD5 sums checked
The downloaded binary packages are in
C:\Users\Zülal\AppData\Local\Temp\RtmpMtDpE4\downloaded_packages
----> Then, I check the library path is writable. But I got the same error again.
By the way, I try to install package with Rstudio Tools --> Install packages part. Again , I got the same error.
Could you please help me? I have to fix that problem immediately. It is crucial for my thesis.
