[R] Labeling Dates of different length on two in axis plot

[Ogbos Okike]

Dear Jim and Bert,
Thank your for looking into this for me. I will try to reproduce a
part of my data and the plot I have.

Data 1:
53 01 02 -1.28792560381641
53 01 06 -1.1854773963453
53 01 08 -1.55920165458006
53 01 15 -1.29196482429683
53 01 20 -1.06082194329819
53 01 22 -1.15430411152234
53 01 24 -1.14775155345262
53 01 26 -1.19116423468105
53 01 28 -0.924542121164923
53 01 31 -0.869543637175866
53 02 03 -0.764466677206437
53 02 05 -0.707705051599105
53 02 07 -0.750908466521414
53 02 16 -1.6848903649715
53 02 20 -0.760876361940755
53 02 22 -0.803816591115474
53 02 26 -0.818160891300922
53 02 28 -0.831013020625678
53 03 04 -1.06661138281899
till the year 2006. The length is 1575

Data B:
57 07 26 -3.62351759422703
57 07 29 -4.51297753038541
57 08 02 -3.29214621128099
57 08 05 -6.44144118698436
57 08 16 -3.09828319252649
57 08 22 -1.58619965424759
57 08 28 -4.3638763217976
57 08 30 -9.93305062749234
57 09 03 -9.29132498735799
57 09 05 -8.50042591710719
57 09 13 -5.58659819576993
57 09 19 -2.4834966827445
57 09 23 -5.69132573226493
57 09 26 -3.6296458026372
to  the year 1994. The length is 1203.

The plot is attached. How to label the x-axis is the problem.
I will send the code in another email so that the moderator will let it go.
Thank again
Best

R has several different graphics systems, and the answer depends on which you are using. In base graphics, the axis() function (see its Help page) may be what you need, but that's just a guess. Others may be able to be more specific.
