Re: [R] Plotting multiple continuous lines with symbols

In your plot and lines function call you specify type="b" which says to use "b"oth lines and points with gaps in the lines around the points. If you change that to type="o" then it will "o"verplot the points and lines (no gaps).

The different types are documented in ?plot.default.

Hope this helps,
