Create STATUS variable for CTFS Datasets

Description

Creates the status variable based on the value of dbh in CTFS datasets of a single census.

Usage

create.status(census, pasoh = FALSE)

Arguments

census CTFS datafile of a single census which does not contain status
pasoh logical, FALSE if datafile is not from Pasoh site

Details

status indicates whether a tree is alive, dead, or a recruit for a single census. Trees that were broken below the point of measurement or shrunk to less than 10 mm are indicated as alive but broken and alive but too small, respectively. At Pasoh a different dbh value for alive but broken was used than at the other sites. dbh is set to NA if status does not equal “A”.

status dbh condition
“A” dbh >= 10 mm alive, dbh measured and value retained
“AS” dbh > 0 & dbh < 10 alive, shrunk, dbh = NA
“AB” dbh == 0 alive but broken, do not alter recorded dbh
“AB” dbh == 5 for Pasoh: alive, but dbh = NA
“P” dbh == -2 recruit in future census, dbh = NA
“D” dbh == -1 dead in this and/or past census, dbh=NA
NA dbh == -9 no information, dbh = NA

Value

returns a data frame of the same number of rows as the input files and with all of the columns of input file plus status
