Hello R Help, I'm working in a project with a software that register date and time data in serial time format. This format is used by excel, for exemple. In this format, 40597.3911423958 is 2011/2/23 09:23:15. First part is number os days since 1900/1/1, and second part is a fraction of a day.
I need to make this transformation in R, and use it to make some algebrian operations. I found that function 'serialNumber' of package 'cxxPack' transform a as.data class object in this format, but without time fraction. But I can't find nothing to do the inverse way, transform serial date format in a POSIX class, for exemple. Since now, thanks for your time and atention. All best, Raoni Associate Researcher Fish Passage Center UFMG, Brazil. "Fica proibido o uso da palavra liberdade, a qual será suprimida dos dicionários e do pântano enganoso das bocas.
