Install package masked functions

Sometimes when I install a new package in an Exploratory project, I get the following confirmation that the package installed, but:
InstallPackage_Expl
This implies that the functions of the installed package are masked by other functions unless specifying the package and function as indicated.

  1. Does this mean that in the installed package, respR, the function ‘convert_val()’ should be written: ’ respR::%>% covert_val()’?
  2. Why do the functions in the installed package seem to work without specifying the pipe?
    Thanks!
