unfindable pgirmess

hello ! I am currently trying to download the package pgirmess but I have only an error message from the system saying he can't find it.

install.packages(pgirmess)
Error in install.packages : objet 'pgirmess' introuvable

I am sorry, I use R Studio in french... I you can help me, I would be very grateful, I am a student and this is for a homework.

You have to use quotes

install.packages("pgirmess")

well, I thought that solved it (thanks by the way, that was a silly mistake :sweat_smile:), but when I tried to use it :

library("pgirmess")
Erreur : package or namespace load failed for ‘pgirmess’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
aucun package nommé ‘rgdal’ n'est trouvé -> this mean he can't find "rgdal"

when I tried to charge rgdal this didn't change anything. An answer ?

What error message you get if you try to install rgdal?

install.packages("rgdal")

it is not in installing rgdal but in openening it

install.packages("rgdal")

There is a binary version available but the source version is later:
binary source needs_compilation
rgdal 1.4-8 1.5-18 TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel) yes
installing the source package ‘rgdal’

This means that an error has occurred and rgdal has not been installed

You are trying to install the latest version from source but you are missing the gdal library, you would have to install it first (in your system not in R), unfortunately I can't tell you how since I'm not a macOS user.

Another option is to install the binary version that is a little older but doesn't require you to install the missing system library. You can do it by answering "no" to this question.

Thank you very much with your answer, I did it with pgrimess and this solved the problem. You saved my day ! :smile:
I can now finish my homework. :relaxed:
