I understand your question, but if I had this kind of data, I would
transform the data first into this form:

# first column: R
# header: I
# data: V
R	2	5	10
2000 0.001000	0.002500	0.005000
2750 0.000727	0.001818	0.003636
3500 0.000571	0.001429	0.002857
4250 0.000471	0.001176	0.002353
5000 0.000400	0.001000	0.002000

set key autotitle columnhead
plot for [n=2:4] 'lab.dat' using 1:n

(Nobody can guarantee that the label in each row is identical in your case.)
