[R] legend for the plot with type = "b"

[Jinsong Zhao]

Hi there,

I plot a simple plot with the following code:

plot (rnorm(1:10), type = "b")
legend("top", "test", lty = 1, pch = 21)

The result is something wired for the line crosses the point in the 
legend while the line does not cross the point in the main plot.

Is there possibility to draw the legend that line does not cross the 
point, i.e., like the pattern in the main plot?

Any help is really appreciated.

Best regards,
Jinsong
