Saikat Kanjilal commented on MAHOUT-1490:
-----------------------------------------
d.mutate( let("gain") equal { col("ArrDelay") - col("DepDelay") } ) seems
rather verbose
how about something like the following:
d.mutate((v= gain) equal { col("ArrDelay") - col("DepDelay") } )
in the above expression v= would essentially create a defined identifier called
v
I will put some more examples in the blog around select with this thinking
Also what about the other functions I am proposing like running a function
around a dataframe (like map) or the slicing functionality around R, should we
keep those as part of this proposal?
