Hello..

 

I am pretty new for R, but if I understand it correctly, when R read data by
doing something like "d <- read.table("/dev/stdin")", it read entire data
first then start processing..

 

Is there anyway I can tweak R around so that it will start processing as
data comes and not load everthing on memory at once? The reason for this is
because we have a case where the data size could get quite large (could
reach terabytes..) and all I am doing would be some basic statistical
report. (Min,Max,Mean..)

 

I have heared something about the PostgreSQL extension where it allows R to
act on certain portion of the PostgreSQL data instead of reading it all. Can
I do something similar to other datasource such as stdin?

 

Thanks,

Soichi
