Hi!
I would like to know, how do you plot more than one data series when
using "coplot"?
I think I know the answer if "plot" is being used:
x <- 1:10
y <- 1:10
y2 <- 1:10* 1.1
plot ( y ~ x, type="n" )
points( y ~ x, type = "b", col = "red" ) # plot the points and lines
for the first series
points( y2 ~ x, type = "b", col = "blue" ) # plot the points and lines
for the second series
But how should it be done with "coplot"?
If I make my question more concrete:
df <- data.frame( x=x, y=y, y2=y2, v=c("a","b")) # using the vectors above
coplot( df$y~df$x | df$v, type="b", col="red") # gives me a coplot of y ~ x
How do I now put points and lines for y2 on the same graphs?
Thank you for your thoughts,
Matthew
