gr.raw {CTFS} | R Documentation

## Unadjusted, Untrimmed Annual DBH Increment for Individual Trees

### Description

Computes the annual dbh increment for each tree and compares it to an expected range of values based on the function `trim.growth`. The range of values is set so high and low as to include all possible growth rates (or so it is believed). This function is intended for use by `biomass` but can be used by itself if unadjusted, raw DBH increments for individuals trees is desired.

### Usage

    gr.raw(census1, census2, rounddown = FALSE)

### Arguments

`census1` | name of census datafile for first census, must be a dataframe, must be of same length as `census2`
`census2` | name of census datafile for second census, must be a dataframe, must be of same length as `census1`
`rounddown` | logical value in caps. When TRUE, if either of census is < 55, then the `floor` of the dbh value / 5 is provided. When FALSE, no change in the dbh is made.

### Details

See `CTFS.growth` for details on the computation methods of growth rates and associated functions.

Any two censuses on a datafile must be used. They do not have to be sequential, only that `census1` has to be before `census2`.

The results of `gr.raw` are annual DBH increments for individual trees, NOT MEAN GROWTH VALUES. A value is returned for each tree. No invalid values should result but this means that no reasonable trimming of growth rates has been done.

### Value

`gr.raw` returns a vector of annual dbh increments. It is not intended for use outside of `biomass` but it will function on its own.
If you want the annual dbh increments for individual trees with the full compliment of computed values, use `growth.indiv`.
