Diameter growth of trees
Description
The 'ficdiamgr' is a fictitious dataframe built to show the structure of
longitudinal data. The dataframe has records of tree diameter growth of
five sample trees, spanning three species.
Usage
data(ficdiamgr)
Format
A time series data containing the following columns:
- tree.id
an ordered factor indicating the tree on which the
measurement is made. The ordering is according to increasing maximum
diameter.
- time
a numeric vector giving the numbers of days since
establishment.
- dbh
a numeric vector of diameter at breast height, in cm.
- site
a factor variable, representing site conditions with two
levels.
- spp
a factor variable, representing tree species with three levels.
Source
This dataframe was built from the 'Orange' data of the datasets package,
by Christian Salas-Eljatib.
Examples
data(ficdiamgr)
coplot(dbh ~ time | tree, data = ficdiamgr, show.given = FALSE)
