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

#3

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

#5

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:

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]]):

#14

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.

#17

This is my output after installing rlang:

And after this i load Rcmdr:

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

same as before..

#19

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