Hello, it seems to be an R bug. It gives strange errors for non-integer exponents:
> version platform i686-redhat-linux-gnu version.string R version 2.4.1 (2006-12-18) > x^47.0 [1] -1.802180e+80 -1.768932e+80 -1.736284e+80 -1.704227e+80 -1.672748e+80 [...] > x^47.10 [1] NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN [...] > x[2]^b [1] NaN But: > x[2] [1] -50.9798 > -50.9798^b [1] -3.131003e+81 So it is not a merely numerical problem. Maybe a bug in memory allocation for vectors containing such big numbers?
