ch |
a single-column data.frame of class character to split |
Mark-recapture software often requires data in split form, with each value in its own matrix cell. Here is a function to split a data.frame into a matrix with each column representing a capture occassion and each row representing an individual's capture history
A matrix of 1's and 0's, a row for each individual.

1 2 3 4 5 6 7 8 9 10 11 | #' 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)
str(chObj)
ch = chObj$ch #' grab our data.frame
ch #' it isn't split
Split.CH(ch) #' returns a matrix
