Rapidminer：转换unix时间戳

Question

Does anybody know a way to convert unix timestamp to date_time attribute?

I tried to use R extensions (my operators are mainly written in R) such as as.POSIXct functions to convert timestamps but it seems that rapidminer doesn't like it and keeps ignoring it.

Any help is appreciated

Thanks

A little known feature of generating attributes is that the input attribute can be the output attribute so no new one is created. In addition, the type of the attribute is changed.

In other words, a construction like this would work as long as the input is milliseconds since the epoch.

unixtime = date_parse(unixtime)
