Dear community,

i would like to install the R Commander, but it doesn't work:

I startet with:
package:Rcmdr
install.packages("Rcmdr")
library("Rcmdr")

But i get the following output:

library("Rcmdr")
Lade nötiges Paket: RcmdrMisc
Lade nötiges Paket: car
Error: package or namespace load failed for ‘car’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
Namensraum ‘vctrs’ 0.2.0 ist bereits geladen, aber >= 0.3.0 wird gefordert
Fehler: Paket ‘car’ konnte nicht geladen werden
Zusätzlich: Warnmeldungen:
1: Paket ‘Rcmdr’ wurde unter R Version 3.6.3 erstellt
2: Paket ‘RcmdrMisc’ wurde unter R Version 3.6.3 erstellt
3: Paket ‘car’ wurde unter R Version 3.6.3 erstellt

Could you please help me?
Thanks a lot

Install the car package

install.packages("car")

Update the vctrs package

install.packages("vctrs")

Note: To avoid posible issues, restart your R session before installing the new packages

Is is still not possible:
R always give me the message in the uploaded picture.
When i click Yes, then the message pops up again and again..

Restart Rstudio before installing the packages

I did this many times. It doesn't work. Thank you for your help, but i think i need more

6

Can you be more specific? what is the actual error message you get?

First, when i load car i get this output:

> install.packages("car")

And then i load vctrs and get this output:

I think this works, should i also do: library(car) and library(vctrs) ??

10

No, restart your R session ones more and then try to load Rcmdr

library(Rcmdr)
11

I startet a new clean session - should i first install the package Rcmdr again in the new clean session before i load the library oder is it still in my r packages?

12

That is not necessary, just load the package.

13

Oh no.. i did it but again the same output:

library(Rcmdr)
Lade nötiges Paket: splines
Lade nötiges Paket: RcmdrMisc
Lade nötiges Paket: car
Lade nötiges Paket: carData
Error: package or namespace load failed for ‘car’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):

4: Paket ‘carData’ wurde unter R Version 3.6.3 erstellt

This is a different issue, you have to update the rlang package

install.packages("rlang")

Alternatively, you can update all your packages at once

update.packages(repos='https://cran.rstudio.com/', ask=FALSE, checkBuilt=TRUE)
15

Ok thank you, i tried both. I still get the same output.
To load Rcmdr is still impossible. Maybe there isn't a solution for my problem and i have to work without the commander..

16

If you have successfully updated rlang it is not possible that you are getting the same output, please be specific and post your error messages, otherwise, we can't help you.

This is my output after installing rlang:

> install.packages("rlang")

And after this i load Rcmdr:

library(Rcmdr)
Lade nötiges Paket: splines
Lade nötiges Paket: RcmdrMisc
Lade nötiges Paket: car
Lade nötiges Paket: carData
Error: package or namespace load failed for ‘car’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):

2: Paket ‘RcmdrMisc’ wurde unter R Version 3.6.3 erstellt
3: Paket ‘car’ wurde unter R Version 3.6.3 erstellt
4: Paket ‘carData’ wurde unter R Version 3.6.3 erstellt

same as before..

The rlang installation has failed becasue the package is already loaded, try restarting RStudio before installing the package, or manually delete the folder.
