The height growth data of four species of bamboo at the Nanjing Forestry University campus in 2016.

data(shoots)

In the data set, there are four variables: `Code`

, `LatinName`

, `x`

and `y`

.
`Code`

is used to save the number codes of different bamboo species;
`LatinName`

is used to save the Latin names of different bamboo species;
`x`

is used to save the investigation times (d) from a specific starting time of growth,
and every bamboo has a different starting time of growth;
`y`

is used to save the measured aboveground height values (cm).

`Code = 1`

represents *Phyllostachys iridescens*, and the starting time (namely `x = 0`

) was defined as 12:00, 3rd April, 2016;

`Code = 2`

represents *Phyllostachys mannii*, and the starting time (namely `x = 0`

) was defined as 12:00, 4th April, 2016;

`Code = 3`

represents *Pleioblastus maculatus*, and the starting time (namely `x = 0`

) was defined as 12:00, 29th April, 2016;

`Code = 4`

represents *Sinobambusa tootsik*, and the starting time (namely `x = 0`

) was defined as 12:00, 18th April, 2016.
