Ther are many ways to do this.

With "big data set" I assume you have really big files that won't fit into memory, right?

Then maybe you could just read the file with some external program or script and send each line to Pd using netsend/netreceive.

If it's smaller files, you could just load the textfiles into four tables and use four tabreads to access them.

Or depending on the size, just load the files into [textfile] and use them as usual: [rewind( the [textfile] and [bang( it over and over.

Or write a [struct] data structure with four float-fields, load the data into data structures and access them with the [pointer]/[get ...] interface.
