Plotting Two y-Axes
Line plot with y-axes on both left and right side.
plotyy(x1, y1, x2, y2, gridp = TRUE, box.col = "grey",
type = "l", lwd = 1, lty = 1,
xlab = "x", ylab = "y", main = "",
col.y1 = "navy", col.y2 = "maroon", ...)x1, x2 |
x-coordinates for the curves |
y1, y2 |
the y-values, with ordinates y1 left, y2 right. |
gridp |
logical; shall a grid be plotted. |
box.col |
color of surrounding box. |
type |
type of the curves, line or points (for both data). |
lwd |
line width (for both data). |
lty |
line type (for both data). |
xlab, ylab |
text below and on the left. |
main |
main title of the plot. |
col.y1, col.y2 |
colors to be used for the lines or points. |
... |
additional plotting parameters. |
Plots y1 versus x1 with y-axis labeling on the left and plots
y2 versus x2 with y-axis labeling on the right.
The x-values should not be too far appart. To exclude certain points, use
NA values. Both curves will be line or point plots, and have the
same line type and width.
Generates a graph, no return values.
