Try:
plot( , xaxt='n', )
axis(1, at=c(1,2,3,4,5, ... all the rest of them ...) )
You might also need to use the label argument to axis()

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
