Memory Experimentation: Rule of Thumb = 10-15 Times the Memory
...t; gc() used (Mb) gc trigger (Mb) max used (Mb) Ncells 270541 14.5 6679958 356.8 11268755 601.9 Vcells 139481 1.1 27476536 209.7 42807620 326.6 linux 'top' now reports 650MB of memory use (though R itself uses only 15.6Mb). My guess is that It leaves the trigger memory of 567MB plus the base 48MB. There are two interesting observations for me here: first, to read a .csv file, I need to have at least 10-15 times as much memory as the file that I want to read---a lot more than the factor of 3-4 that I had expected. The moral is that IF R can read a .csv file, one need n...

Help choosing the right card
I have been doing a lot of reading forums and elsewhere but am somehow unable to connect the dots. Here is what I am trying to accomplish initially and then wish for it to grow bigger from here on. I have two POTS (Analog) line that would connect to the Asterisk Box. I have, to begin with 5 IP phones (PoE), all connected to a switch. Asterisk Box with a LAN card also connects to the same switch.
