I can't install the packages

I can't install the packages that i need.

i try to install them by : install packages and then write one by one the packages. Then if i do library("nameofthepackage" it says it doesn't exist.

How can I do? is there a problem with the internet? I am with the university wifi.

System Information:

  • R Version: 4.1.1

You install packages by calling install.packages("[package name]"). Replace [package name] with the name of the package, and be sure to keep the quotes. When calling library([package name]), quotes are not required but can be used.

Thank you for your answer but it doesn't work.
it says this:

Warning in install.packages :
il pacchetto ‘[tidyverse]’ non è disponibile for this version of R

Una versione di questo pacchetto per la tua versione di R potrebbe essere disponibile altrove,

Errore in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
non c'è alcun pacchetto chiamato ‘stringi’

You need to drop the square brackets. Use this:


i download it and it says this:

apertura URL 'https://cran.rstudio.com/bin/macosx/contrib/4.1/summarytools_1.0.0.tgz'
Content type 'application/x-gzip' length 1467792 bytes (1.4 MB)
downloaded 1.4 MB

The downloaded binary packages are in

then i run this to see if it exists and it says there is an error:

Errore: caricamento pacchetto o namespace fallito per ‘summarytools’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
non c'è alcun pacchetto chiamato ‘stringi’

You are missing a package dependency you have to install it first
