Subject: [Rd] cummax / cummin for complex numbers
Message-ID: <9591F061-56E7-4FA6-9A84-AED2C3B56F32@oracle.com>

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
