When I load some packages, this keeps coming out:
Error in unloadNamespace(package) :
namespace 'IRanges' is imported by 'Biostrings', 'XVector', 'AnnotationDbi' so cannot be unloaded
Error in library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc, :
Package 'IRanges' version 2.4.7 cannot be unloaded
Does anyone know what this mean?
