CTFS.readwrite {CTFS} | R Documentation

## Overview of Functions that Read, Write and Restructure CTFS data files

### Description

Provides an overview of the functions that allow asci data files to be read into R using CTFS variable defintions, to be restructured for use in various analyses, to be accessed with ease and to be saved for further use.

### Details

FUNCTIONS THAT READ, WRITE AND RESTRUCTURE CTFS DATA FILES

`sep.data`
  Re-structures a dataframe into a list of dataframes by values of a Column in the dataframe using a variable in the initial dataframe. Replacement for: `splitdata`.
`sep.vct.data`
  Re-structures a dataframe into a list of dataframes by values of a Column in the dataframe using a vector of a variable not in the initial dataframe. Replacement for: `splitdata`.
`mergecensus`
  Merges two Censuses into one dataframe and sets the value of `status`.
`create.status`
  Sets the value of `status` for a single census dataset.
`texttordata`
  Creates CTFS R dataframe from any tab delimited text file.
`sep.species`
  Separate One or More Dataframes of Tree Records from a List. If a single species name is provided, a data frame of the tree records of that species is returned. This is the same as `load.species`. If a vector of species names is provided, then a list of the dataframes of those species is returned.
`load.species`
  Separate One or More Dataframes of Tree Records from a List. A more limited function than `sep.species`. The same effect can be achieved with `siteyear.spp$sppname` where `siteyear.spp` is a list created using `sep.data`, eg. `tst.bci90.spp` and `sppname` is one of the list names.
`readelevdata`
  Read a Text or RData dataframe and Make a matrix, Specifically for Elevation Data.

FUNCTIONS FOR FORMATTING RESULTS

`assemble.demography`
  Reformat the Output from Demographic Functions from list to dataframe.
`assemble.table.each`
  Reformat the Output from Demographic Functions from list to dataframe.

FUNCTIONS FOR CREATING VECTORS

See `CTFS.groupcats`.

### Note

For developers: The CTFS readwrite functions are found in a file approximately named: `readandwrite.R`
