Identify trees with major errors in DBH measurments. A major error correspond to a relative individal productivity (or growth) is above a given percentage (set by 'maxrel') of the mean productivity computed at a site. Additionnaly, flagged trees that died at next census interval are also flagged. Option to see DBH measurement (=draw.graph) of flagged trees or print a csv (output.errors) are given.

|
DF |
a data.table |
site |
provide the full name of your site (in lower case) i.e. 'barro colorado island' |
strangler |
TRUE or FALSE, if TRUE, strangler figs tree are flagged (upon a list to published soon) |
maxrel |
a numeric value setting the threshold over which relative productivity is assumed to be too high (usually set at 20 percents) |
draw.graph |
TRUE or FALSE, if TRUE, draw graph for trees with 'erroneous' DBH measures/productivity |
output.errors |
TRUE or FALSE, if TRUE, creat a CSV file with all trees with erroneous DBH measures/productivity |
exclude.interval |
a vector (i.e. c(1,2)) indicating if a set of census intervals must be discarded from computation due for instance to a change in protocol of measurment |
a data.table (data.frame) with all relevant variables.
