Dear all, in R 3.1.0, this is happening:
cummin(c(1+1i,2-3i,4+5i))
Error in cummin(c(1 + (0+1i), 2 - (0+3i), 4 + (0+5i))) : 'cummax' not defined for complex numbers
cummax(c(1+1i,2-3i,4+5i))
Error in cummax(c(1 + (0+1i), 2 - (0+3i), 4 + (0+5i))) : 'cummin' not defined for complex numbers It may be fixed in R-devel, but I thought I'd mention it to make sure ... Best, Michael
The help file for cummax/cummin in 3.1.1 specifically states: x a numeric or complex ****(not cummin or cummax)**** object, or an object that can be coerced to one of these. So why would you expect it to work for cummin or cummax when you pass a complex 'x'? Regards, Marc Schwartz
