CensusToCaptHist | R Documentation |
This function takes a common census table, consisting of a pair of vectors with ID and observation date, and converts it into a capture-history matrix to be used as part of a BaSTA data input.
CensusToCaptHist(ID, d, dformat = "%Y", timeInt = "Y")
ID |
A vector with individual IDs. |
d |
A vector of dates when each individual was observed. |
dformat |
Defines the date format for |
timeInt |
A one character string specifying which time interval should be used between capture occasions. Arguments are “ |
The d
argument can be specified as an object of class POSIXct
or POSIXlt
, as a vector of integer time intervals or as a character string indicating the day, month and year. (e.g. dd/mm/yyyy
, mmddyyyy
, mm-dd-yyyy
etc.). When d
is of class character
then argument dformat
needs to be specified using the same conventions as in function format.POSIXct
for objects of class POSIXct
or POSIXlt
.
