How to do Microarray Metadata analysis using R

Question

[xxxxxxxx]

I want to learn microarray metadata analysis using R. The tutorials that I am following all are for an older version of R. Where can get an R script for microarray metadata analysis which will work for the R version >= 4.0?

I am not sure what is the issue. These should still work with R 4.0.x. In some cases, a package may be deprecated, in which case you just need to download the tar.gz of the final version [prior to deprecation] and then install this via install.packages()

yes I tried that but after running this-

shiny::runApp('metaOmics', port=9987, launch.browser=T)

getting error like this at the end-

It redirects to the browser which shows the error. Please find the attached screenshot.
