rpryr

library(pryr) returns a message. Registered S3 method overwritten by 'pryr': method from print.bytes Rcpp

When I active a package called pryr. It returns a message

    library(pryr)

    Registered S3 method overwritten by 'pryr':
    method      from   
    print.bytes Rcpp.

I would like to know what does it is mean?
However the package runs properly. That message shows only one time each session.

Solution

  • It means that both Rcpp and pryr have an S3 method (a function) called print.bytes. That is, a print method for an object of the bytes class.

    Since you now loaded pryr, the function from pryr will be used, not the one from Rcpp.

    This might mean that objects of class bytes will be displayed differently after loading pryr, but since it's just a print method, this is unlikely to have serious consequences.
