Write species-plot observations and site information to Turboveg database.
tv.write(x, site, name, tvadmin, remarks, dict = "", cover = c("code", "perc"),
drop = FALSE, obl = TRUE, overwrite = FALSE, ...)Five files will be created in "tv_home/Data/databasename" directory. *tvabund.dbf* with occurrence information n long format, *tvhabita.dbf* with plot information, remarks.dbf with comments longer then 255 characters, *TvAdmin.dbf* with plot UUID's and tvwin.dbf with information about taxonomic reference list, and dictionary used.
(data.frame) Either observations data.frame with RELEVE_NR, TaxonUsageID and COVER_CODE (see tv.obs) columns or vegetation matrix of class "veg".
(character) Header data for plots.
(character) Name of the new database.
(data.frame) Dataframe with plot UUID's and Turboveg columns from TvAdmin.dbf. A new file with new unique identifiers will be created if omitted.
(data.frame) Remarks in Turboveg format if the comments for individual plots exceed 254 characters. See remarks.dbf in Turboveg databases. An empty file will be created if omitted.
(character) Turboveg dictionary name
(logical) Use of covercodes or (mean) cover percentages, see Details.

By default Covercode is written to Turboveg. This is only meaningful, if correct CoverScales are given in the site dataframe. Unique plot ID's are stored in *TvAdmin.dbf*. If you want to preserve already given UUID's you have to prepare an appropriate data.frame. Look for existing *TvAdmin.dbf* files for necessary columns.
