Arguments

x: An object of class brokenstick.
newdata: A data.frame or matrix
hide: Character indicating which knots should
.x: The x argument of the predict.brokenstick() function.
group: A vector with group identifications
color_y: A character vector with two elements specifying the symbol and line color of the measured data points
size_y: Dot size of measured data points
linetype_y: Line type of data points
shape_y: Symbol for data points
color_yhat: A character vector with two elements specifying the symbol and line color of the predicted data points
size_yhat: Dot size of predicted data points
linetype_yhat: Line type of predicted data
shape_yhat: Symbol for predicted data
color_imp: A character vector with two elements specifying the symbol and line color of the imputed data
size_imp: Dot size of imputed data
ncol: Number of columns in plot
xlab: The label of the x-axis
ylab: The label of the y-axis
xlim: Vector of length 2 with range of x-axis
ylim: Vector of length 2 with range of y-axis
show: A logical vector of length 3. Element 1 specifies whether the observed data are plotted, element 2 specifies whether the broken stick are plotted, element 3 specifies whether imputations are plotted. The default is c(TRUE, TRUE, FALSE).
n_plot: A integer indicating the number of individual plots. The default is 3, which plots the trajectories of the first three groups. The n_plot is a safety measure to prevent unintended plots of the entire data set.
scales: Axis scaling, e.g. "fixed", "free", and so on
theme: Plotting theme
whatknots: Deprecated.
...: Extra arguments passed down to predict.brokenstick().
