Identify changes within a discrete variable. These values can be used to
pre-specify breakpoints within the segmentation model using
segment_behavior.
find_breaks(dat, ind)A data frame containing the data for each animal ID.
character. The name of the column storing the discrete variable of interest.
A vector of breakpoints is returned based on the data provided. If
wishing to identify separate breakpoints per animal ID, this function
should be mapped onto a list generated by df_to_list.
#simuluate data
var<- sample(1:3, size = 50, replace = TRUE)
var<- rep(var, each = 20)
id<- rep(1:10, each = 100)
#create data frame
dat<- data.frame(id, var)
#create list
dat.list<- df_to_list(dat = dat, ind = "id")
#run function using purrr::map()
breaks<- purrr::map(dat.list, ~find_breaks(dat = ., ind = "var"))
#or with lapply()
breaks1<- lapply(dat.list, find_breaks, ind = "var")
