[R-SIG-Finance] Quantmod SMA not working

[Jeffrey Ryan]

The problem is that fTrading also has an SMA function.  You can either
load it before loading quantmod/TTR or ... not use it??

Note the conflict when you call library(fTrading) _after_ you load quantmod/TTR

Is there a function in fTrading that you need that isn't in TTR
