Hi, I want to apply ^ operator to a vector but it is applied to some of the elements correctly and to some others, it generates NaN. Why is it not able to calculate -6.108576e-05^(1/3) even though it exists?
tmp [1] -6.108576e-05 4.208762e-05 3.547092e-05 7.171101e-04 -1.600269e-03 > tmp^(1/3) [1] NaN 0.03478442 0.03285672 0.08950802 NaN > -6.108576e-05^(1/3) [1] -0.03938341 ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
