plot log scale on y axis using zoo object (with plot.zoo)
A warning isn't an error. As far as I can tell my output works using:
plot(zoo(1:10,1:10)) plot(zoo(1:10,1:10),log='y')
Warning message: In plot.xy(xy.coords(x, y), type = type, ...) : "log" is not a graphical parameter Jeff

Hi,
I'd like to plot a times series with a log on the y-axis. I'm plotting a zoo
object as it is easier to format the dates on the x-axis. Unfortunately,
log="y" does not work with plot.zoo. Any idea?
Here's a reproducible example
x <-seq(1,10000,length.out=10)
plot(x,log="y",type="l") ?#works
z <- zoo(seq(1,10000,length.out=10),
? ? as.Date(c("1992-01-10", "1992-01-17", "1992-01-24", "1992-01-31",
? ? ? "1992-02-07", "1992-02-14", "1992-02-21", "1992-02-28", "1992-03-06",
? ? ? "1992-03-13")))
plot(z,log="y") ? ? ? ? ?#gives error
