Answer 1

This is usually caused by multiple packages having the same named functions. Have a look at this answer - it offers some insight into your query https://stackoverflow.com/a/59093803/8158951

In your case, the last loaded package is taking precedence for the function name of the one you need to plot.

It would assist if you can provide a reproducible example with the code you are using, but I'll try and provide some guidance.

Where duplicate function names occur, R provides a warning like the one you refer to above. This can be mitigated by adding the name of the required package before the function call as follows PackageName::FunctionName .

If plotting is an issue for you, and assuming you are using ggplot, you could try this:

ggplot2::ggplot()
