r - Read a reproductible sample of data from multiple CSVs -

i'm working several large csv files, large enough can't efficiently load them memory.

instead read sample of data each file. there have been other posts topic (such load small random sample large csv file r data frame ) requirements little different read in same rows each file.

using read.csv() skip , nrows=1 slow , tedious.

does have suggestion how efficiently load same n rows several csvs without reading them memory?
