ggplot2 library not working

[Sara Ferrando]

Hi everyone,

I used ggplot2 before.

Now I downloaded and installed the new version or R

R version 4.1.2 (2021-11-01) -- "Bird Hippie"

Copyright (C) 2021 The R Foundation for Statistical Computing

Platform: x86_64-apple-darwin17.0 (64-bit)

I installed ggplot2

> install.packages("ggplot2")

and then I load it

> library (ggplot2)

and the error message (in Italian) was:

Errore: caricamento pacchetto o namespace fallito per ‘ggplot2’:

 .onLoad fallito in loadNamespace() per 'vctrs', dettagli:

  chiamata: run_on_load()

  errore: non trovo la funzione "run_on_load"

And it sounds more or less like:

Error: package loading or namespace failed for ‘ggplot2’:

 .onLoad failed in loadNamespace() for 'vctrs', details:

  call: run_on_load()

  error: function "run_on_load" not found

May someone help me to understand what I need to do? Many thanks in advance.

Sara

Dear Sara.

I cannot reproduce your problem in Windows 10 with the same configuration. Maybe it is something related to the Mac version?

Dear Julio,

without a real understanding of the problem, I tried to install the vctrs package. And now it works.

Sorry for bothering, I was pretty desperate because I used ggplot2 fine until a couple of weeks ago.

Many thanks for your answer.

Best

Sara
