I tried to install package
ggplot2 in R Studio Desktop Windows. But I got the error message when I used the library :
> install.packages("ggplot2") Installing package into ‘C:/Users/Rifqi/Documents/R/win-library/4.0’ (as ‘lib’ is unspecified) trying URL 'https://cran.rstudio.com/bin/windows/contrib/4.0/ggplot2_3.3.3.zip' Content type 'application/zip' length 4068844 bytes (3.9 MB) downloaded 3.9 MB package ‘ggplot2’ successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\Rifqi\AppData\Local\Temp\Rtmp005k6i\downloaded_packages > library(ggplot2) Error: package or namespace load failed for ‘ggplot2’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘utf8’ >
What should I do to fix this problem?
