Can someone please enlighten me as to why the following happens?
> -2.7^8.6
[1] -5125.407

> p<- -2.7
> q<- 8.6
> p^q

[1] NaN
R seems perfectly able to calculate -2.7^8.6, but fails when the exact same values are assigned to variables and then the computation is repeated. Thanks in advance for any suggetsions.
