After accessing allDat with calls like below within another function ffDat <- allDat[1,] nEvents <- length(ffDat$physical$position) pos <- ffDat$physical$position[1:nEvents] several times to retrieve information, I encounter segmentation faults which forces me to abort out of R. I'm wondering what I should be doing to prevent the segmentation faults. Thanks...
