In the data set, there are four variables: code
, species
, time
and height
.
code
is used to save the number codes of different bamboo species;
species
is used to save the Latin names of different bamboo species;
time
is used to save the observation times (d) from a specific starting time of growth,
and every bamboo has a different starting time of growth;
height
is used to save the measured aboveground height values (cm).
code = 1
represents Phyllostachys iridescens, and the starting time (namely time = 0
) was defined as 12:00, 3rd April, 2016;
code = 2
represents Phyllostachys mannii, and the starting time (namely time = 0
) was defined as 12:00, 4th April, 2016;
code = 3
represents Sinobambusa tootsik, and the starting time (namely time = 0
) was defined as 12:00, 18th April, 2016;
code = 4
represents Pleioblastus maculatus, and the starting time (namely time = 0
) was defined as 12:00, 29th April, 2016.
