Masked objects when loaded. Does this make it impossible for the package to perform its function? How to resolve?

I’m having trouble executing some Spacialpoint Dataframe object commands. When I load the packets, two of them appear masked by others.

I know that masking occurs when two packages have functions with the same names. Masked objects prevent the package from performing its function? Does this make it impossible for the package to perform its function? How to "unmask" these packages so I can use the packages correctly?

The following message appears:

> library("raster")

Attaching package: ‘raster’

The following objects are masked from ‘package:MASS’:

I appreciate the help.

You can specify from which package to use the function with ::

rgdal::buffer()
raster::buffer()

It is always recommended to specify from which package we are using the function as shown above.

What’s more, you can access a function with the :: without loading the package with the library().
