It is actually using your xlim. The default axis type leaves some padding (white space) at the ends. (Notice that the plot line _does_ end at c(30, 1000).) Try: plot(..., xaxs = "i") to eliminate the padding. For customized axis labels, try plot(..., axes = F) and then use the "axis" command to generate the axes. You can specify exactly where you want the ticks to occur and what text gets placed next to them.
