Hi, R-Helpers,
I would like to ask about multiple graphs in one figure. I tried to execute
the following codes.
xlim - c(1,100)
ylim - c(1,4)
plot(NA, xlim=xlim, ylim=ylim)
x - c(1:100)
for(j in seq(1,10,by=1)) {
y - j*x^2+log(j)
lines(x, y)
}
In the above codes, I had to

In results, the figure did not contain all data since most of data were

Hi,
It's easy with ggplot2,
library(ggplot2)
## create an empty plot
p - ggplot(map=aes(x,y))
## create a dummy list of data.frames with different ranges
d - replicate(4, data.frame(x=sample(1:10,1)+rnorm(10),
y=sample(1:10,1)+rnorm(10)),
The best approach is to calculate the limits before doing any plotting and set
them appropriately. You could use your loop to compute y, but instead of
calling lines, store the values, then use a function like matplot (or ggplot2
or lattice) to do the plotting.
