as.rwl
Attempts to turn its argument into a rwl object.
as.rwl(x)
x |
a |
This tries to coerce x into class c("rwl","data.frame"). Failable.
An object of class c("rwl", "data.frame") with the series in
columns and the years as rows. The series IDs are the
column names and the years are the row names.

## 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)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
