Clumsy but this should do it.  

aa$set  <-  rep("a", length(aa$position))
bb$set  <-  rep("b", length(bb$position))

(mydata  <-  rbind(aa,bb))

p  <-  ggplot( mydata , aes( position, count, colour = set  )) + geom_line()
p

Subject: [R] geom_line: How to plot two data sets having different
maximum X-axis values in a single plot?

Hello, I just started  to learn R and ggplot2. Can someone help?

How to plot two data sets having different maximum X-axis values in a
single plot?

For example, I have two data sets showed below. Using position as X, and
count as Y, how can I plot them out in different color lines within a
single plot using ggplot2 geom_line?

dataset a:

position count

1    3

2    9

3    10

4    15

5    19

6    28

7    15

8    13

9    11

10    5

dataset b:

position count

1    4

2    8

3    16

4    17

5    19

6    10

Thanks a lot!

Jim
