Combine Tree-Ring Data Sets
This function combines any number of data.frames of
tree-ring data into one data.frame.
combine.rwl(x, y = NULL)
x |
either a |
y |
a |
The sequence of years in each data.frame must be
increasing and continuous. The output produced by the function
also fulfills this condition. If the input is differently formatted,
the result will be wrong.
An object of class c("rwl", "data.frame") with the series in
columns and the years as
rows. The keycodes are the column names and the years are the row
names.
