Dear all,

When I load a library, this keeps coming out:

library("AnnotationDbi")
Loading required package: IRanges
Error in unloadNamespace(package) : 
  namespace ‘IRanges’ is imported by ‘AnnotationDbi’, ‘XVector’, ‘Biostrings’ 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.

What does this mean? How could I solve it?

Best,

Bef
