I am trying to generate a plot whose x-axis values are the following:

 data_out[,1]
  [1] 1979 1958 1937 1916 1895 1874 1853 1832 1811 1790 1769 1748 1727 1706 1685 1664 1643 1622 1601 1580 1559
 [22] 1538 1517 1496 1475 1454 1433 1412 1391 1370 1349 1328 1307 1286 1265 1244 1223 1202 1181 1160 1139 1118
 [43] 1097 1076 1055 1034 1013  992  971  950  929  908  887  866  845  824  803  782  761  740  719  698  677
 [64]  656  635  614  593  572  551  530  509  488  467  446  425  404  383  362  341  320  299  278  257  236
 [85]  215  194  173  152  131  110   89   68   47   26   25   24   23   22   21   20   19   18   17   16   15
[106]   14   13   12   11   10    9    8    7    6    5    4    3    2    1

The y-axis values are:

> data_out[,2]
  [1]  1.01709  1.09454  1.16331  1.21673  1.26098  1.30297  1.33905  1.37466  1.40690  1.43407  1.46022

 [23]  1.73706  1.75634  1.77562  1.79505  1.81393  1.83259  1.85197  1.87105  1.88949  1.90792  1.92649
 [34]  1.94479  1.96263  1.98029  1.99677  2.01212  2.02692  2.04183  2.05648  2.07071  2.08329  2.09510
 [45]  2.10593  2.11636  2.12563  2.13423  2.14317  2.15116  2.15739  2.16426  2.17121  2.17796  2.18490
 [56]  2.19103  2.19751  2.20357  2.21056  2.21642  2.22264  2.22861  2.23448  2.24007  2.24601  2.25113
 [67]  2.25593  2.25842  2.26077  2.26183  2.26223  2.26224  2.26133  2.25868  2.25493  2.25130  2.24704
 [78]  2.24123  2.23236  2.22251  2.20842  2.19076  2.17490  2.15480  2.13716  2.11967  2.10428  2.08815
 [89]  2.07497  2.06104  2.05527  2.05412  2.06270  2.08828  2.09092  2.09158  2.09290  2.09495  2.09370
[100]  2.09703  2.10551  2.10771  2.10916  2.11557  2.12741  2.13782  2.14946  2.16577  2.18978  2.21518
[111]  2.25129  2.27978  2.32903  2.40820  2.50683  2.64452  3.06182  3.97841 35.81950

I cannot get my ploy start with the tick label "1". Surprisingly it keeps starting from 0 regardless of the usage of the graphic parameter xlim.
I tried many different combinations of the parameters appearing in the plot instruction.
I also tried to sort the x-axis value in increasing order.

> plot(sort(data_out[,1]),sort(data_out[,2],decreasing=T),xlim=c(1,1979),ylim=c(1,35),main="Intrinsic Dimensionality of 2D Swiss Roll",font.main=2,cex.main=1.5,col.main="red",xlab="Number of Nearest-Neighbors",ylab="Dimension",type="l",lab=c(10,10,3))

How can I get the x-axis tick labels to be (a subset of) the x-axis values, that is:

  1    2    3    4    5    6    7    8    9   10   11   12   13   14   15   16   17   18   19   20   21
 22   23   24   25   26   47   68   89  110  131  152  173  194  215  236  257  278  299  320  341  362
 383  404  425  446  467  488  509  530  551  572  593  614  635  656  677  698  719  740  761  782  803
 824  845  866  887  908  929  950  971  992 1013 1034 1055 1076 1097 1118 1139 1160 1181 1202 1223 1244
1265 1286 1307 1328 1349 1370 1391 1412 1433 1454 1475 1496 1517 1538 1559 1580 1601 1622 1643 1664 1685
1706 1727 1748 1769 1790 1811 1832 1853 1874 1895 1916 1937 1958 1979

Thank you in advance,
