## Toy
n <- 100
## Make a data.frame that is tree-ring like
base.series <- 0.75 + exp(-0.2 * 1:n)
foo <- data.frame(x1 = base.series + abs(rnorm(n, 0, 0.25)),
x2 = base.series + abs(rnorm(n, 0, 0.25)),
x3 = base.series + abs(rnorm(n, 0, 0.25)),
x4 = base.series + abs(rnorm(n, 0, 0.25)),
x5 = base.series + abs(rnorm(n, 0, 0.25)),
x6 = base.series + abs(rnorm(n, 0, 0.25)))
# coerce to rwl and use plot and summary methods
foo <- as.rwl(foo)
class(foo)
plot(foo, plot.type="spag")
summary(foo)
```
