This is a working example of the issue:
Also defined by ‘spacetime’ Found more than one class "xts" in cache; using the first, from namespace 'quantmod' #35
For my work . . .
- I must have package xts directly on the search() path. I call xts functions without "::"
- I must use the package DMwR (that imports quantmod that requires xts). I call "DMwR::function."
The critical point is (2.) If from DESCRIPTION, I remove
Imports:
DMwR
then the message
Also defined by ‘spacetime’ Found more than one class "xts" in cache; using the first, from namespace 'quantmod'
is no longer there.
But, for my work I still need (1.) and (2.). Therefore, in the DESCRIPTION, I still need . . .
Depends:
xts
Imports:
DMwR
