Comparison plots

Question

Hi I'm currently analysing some data from a bioassay that we did on pea aphids in the lab. We applied two different insecticides observe the LD50.

What I would like to do is create a plot that includes concentration (con) and have the data from both the leaf disk (ld) and the whole leaf (wl) on one plot so I can compare both sets of data. I am able to plot one at a time easily but really stumped on how both on one graph. I have looked at a lot of tutorials on line but I'm not finding anything that is helpful. I have included my data set below.

con ld wl 0.01 90% 19% 0.00316 47% 7% 0.001 24% 6% 0.000316 9% 8%

Thank you in advance

Debz.

I expect you are looking for something like this?

dat <- data.frame(con = c(0.01,0.00316,0.001,0.000316),
                  ld = c(90,47,24,9),
                  wl = c(19,7,6,8))

plot(dat$con, dat$ld, type="n", xlab="Concentration", ylab="Percent (%)")
lines(dat$con, dat$ld)
lines(dat$con, dat$wl, col="green")
