Dear useRs,
I have this dataset (D) with three columns.
> dput(D)
structure(c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,
16, 17, 18, 19, 20, 2.990484802, 3.005018792, 3.019552781, 3.03408677,
3.048620759, 3.063154749, 3.077688738, 3.092222727, 3.106756717,
3.121290706, 3.135824695, 3.150358684, 3.164892674, 3.179426663,
3.193960652, 3.208494642, 3.223028631, 3.23756262, 3.252096609,
3.266630599, 0.488381368, 0.976762736, 1.465144104, 1.953525472,
2.44190684, 2.930288208, 3.418669576, 3.907050944, 4.395432311,
4.883813679, 5.372195047, 5.860576415, 6.348957783, 6.837339151,
7.325720519, 7.814101887, 8.302483255, 8.790864623, 9.279245991,
9.767627359), .Dim = c(20L, 3L))
The first column represents the index values while the second column contains
the response values. The third column in actually the percentage increase in
the response values by increasing a unit index value.
I made a plot and obtained a single line by;
>plot(D[,1],D[,2],type="l")
The primary y-axis represents the usual response values. Now I want to add a
secondary y-axis representing the percentage value shown against response
value. So that, when a reader sees the graph she could easily visualize not
only the decimal response value but also the percentage increase against that
response value from the secondary axis without plotting any extra line.
I thank you in advance,
Stay Blessed!!!!
