Plot of hauls position
The function plots the haul positions starting from table A file (TA, hauls data).
haul.plot(TA, GSA = NA, country=NA, year = NA, type = "m", labels = FALSE, land = countries,format="MEDITS")
TA |
data frame containing the hauls data (TA, table A). |
GSA |
numeric value of the GSA code. The default value is NA. |
country |
string value indicating the selected country for the analysis in case the analysis should be performed by country |
year |
numeric value or vector containing the years to be selected for coordinate plotting. The default value is NA. |
type |
string value used to indicate whether ("b") both shooting and hauling coordinates or ("m") the mean coordinate values should be plotted. |
labels |
logic value used to indicate whether (T) haul's code should be used as labels or not (F). |
land |
shapefile of countries. Made with Natural Earth. Free vector and raster map data @ naturalearthdata.com. |
format |
character value that define the format of the used cordinates. The two allowed values are: "MEDITS" for for MEDITS coordinates format; "degrees" for coordinates reported in decimal degrees format (dd.ddd). The default value is "MEDITS" |
The function returns the plot whith the positions of the selected hauls.
