Need help with Multiple Imputation - any data scientist available?

Dear r-community,

Let me briefly introduce myself. I am new here (as you can see) and also new to R/Rstudio. I am in the process of completing my MA (Psychology by Research). Unfortunately, training on statistical analysis applications/software has been sub-par. As such I am busy teaching myself RStudio (as this seems one of the more popular means to run data analysis, at least in my field).

At the moment I struggling my way through several R-courses, but at the same time I am rushing against a deadline to finish my MA dissertation.

Is there anyone available/willing that could perhaps guide me on doing a multiple imputation of my dataset (it seems straightforward, until you have to start checking multicollinearity and so many other factors)?

Many thanks in advance to those taking the time to read this.
