fit_all_trajectories: Apply trajectory fitting to each subject in a dataset

In hafen/hbgd: Healthy birth, growth & development

Description

Apply trajectory fitting to each subject in a dataset

Usage

fit_all_trajectories(dat, fit, xg = NULL, checkpoints = 365 * c(1:2),
  z_bins = -2)

Arguments

dat	a data frame containing data for several subjects or a data frame with one row per subject, as obtained from by_subject
fit	an object returned from get_fit
xg	grid of x points at which the fit should be evaluated for plotting (if NULL it will be set to an equally-spaced grid of 150 points across x)
checkpoints	x values at which to compute "checkpoints" of the subjects's growth trajectory to compare to other subjects
z_bins	a vector indicating binning of z-scores for the subject's trajectory at each checkpoint with respect to the the WHO growth standard

Examples

## Not run: 
cppfit <- get_fit(cpp, y_var = "wtkg", method = "rlm")
cpptr  <- fit_all_trajectories(cpp, cppfit)
cpptr$fit[[1]]
plot(cpptr$fit[[1]])

## End(Not run)
