Description

Attempts to turn its argument into a rwl object.

Usage

as.rwl(x)

Arguments

x

a data.frame or matrix with series as columns and years as rows

Value

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.

Details

This tries to coerce x into class c("rwl","data.frame"). Failable.

Examples

# NOT RUN {
library(graphics)
library(stats)
library(utils)
## 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)
# }
