Thank you very much for your fast help, unfortunately it did not yet resolve the problem.
- After installation of the package "backports" I received the following message for the package "psych":
install.packages("psych")
Installing package into �C:/Users/EdlerJ/Documents/R/win-library/3.6�
(as �lib� is unspecified)
Warning in install.packages :

There is a binary version available but the source version is later:

- For "hmisc" I was asked "Do you want to install from sources the package which needs compilation?" and I clicked "No". After installation the library function lead the following error message:
library(Hmisc)

- Package mice seems to have worked.
