I meant type in "?sample" to see what the 'sample' function does. ?For
example, to select 50 random rows,
?[1] 1004 ?857 1219 1850 ?480 ?543 1466 1498 1854 ?922 1713 ?621 ?414
1830 ?105 ?817 ?906 ?825 1329 1500 1806 1623 ?186 ?352 1270 1727 1170
518 1743 ?370 ?964 ? 20 ?710 ?870 ?248 1227 ?594 ?471 ?704 1751
[41] 1942 1435 1944 1057 ?849 1886 ?290 ?130 ? 48 1195

Hi dear list,
I have a list of around 2000 identifiers aranged in a dataframe in one
column and I would like to choose a random subset of these. I wonder
if somebody can tell me if I could do this with R...
Thank you so much!
