I have 3 xts objects: test, cond1, cond2
You can download here:

My problem is very simple.

test [ cond1 < cond2] = NA                           THIS WORKS

test [ cond1 < cond2] = -test [ cond1 < cond2]       THIS DOESN'T WORKS

Why?

My objective is to substitute all values in test (when cond1 < cond2) with
the corresponding values of test but with negative sign
