The reason that it's easy to produce dotcharts or barplots in R with
data like yours, and difficult to produce a line plot, is because
dotcharts and barplots are appropriate for your data, whereas a line
plot is not. Since the values on the x-axis represent names,
and those names are not measured on any kind of ordinal scale,
connecting the points on a plot would be at best meaningless and at
worst deceptive.
Of course, one of R's charms is that it provides ample rope to hang
yourself it that's what you really want to do. You could create a
line plot with a custom axis labeled in what ever way you want, to
produce a whatever sort of plot you wanted. I'll leave it to you to
figure out the details.

Hi All
I have data like this
tom randy mike dan doug
height 150 152 155 134 141
I am trying to create a line plot, with names on X-axis and height measure
on Y. how can i get it through R.
I could get several versions which are close (dotchart, bargraph), but not
quite the same thing.
I am looking for something like

with option to add more lines, such as weight measurement for above data.
Thanks,
