Collapse.CH: Collapse a capture history matrix
In EasyMARK: Utility functions for working with mark-recapture data.

Description Usage Arguments Details Value Author(s) See Also Examples

Collapses a capture history matrix into a single-columned data.frame.

1	Collapse.CH(ch)

`ch`	Input a `matrix` of 1's and 0's to be collapsed. Most likely this matrix will have one individual per row and one capture occassion per column.

Some mark-recapture programs want data in collapsed form, as a character string. This function will collapse a matrix into a single columned character sring of ones and zeros.

data.frame of capture histories

Returns a single-columned data frame of the capture histories as a character string.

#' set up variables to be used by Simulate.CH for ten individuals
N = 10 
x1 = rnorm(N) #' each trait is normally distributed

#' Run Simulate.CH with a constant recapture probability
chObj = Simulate.CH(surv.form = 1 + 0.15*x1, p.constant = 1, N = N)

attributes(chObj) #' see what is inside our object
ch = chObj$ch_split #' grab our matrix from the list
ch #' lets look at it

Collapse.CH(ch) #' now let's turn it into a data.frame
