Plot Coefficient Function
Plot coefficient values formatted in a data frame returned by function coef.
plotCoef(object, smooth = FALSE, ...)
object: A data.frame returned by function coef.smooth: A logical value, default FALSE. If TRUE, plot the coefficients as smooth lines; otherwise, plot the coefficients as piece-wise constant step functions....: Other arguments.A ggplot object.
To plot estimated coefficient functions from different models together, one can first combine the data frames returned by coef, and then call plotCoef, for example, plotCoef(rbind(coef(fit1), coef(fit2))).
To specify the time range of the plot, one can either utilize the ggplot functionality, say plotCoef(coef(fit)) + xlim(2, 10); or manipulate the data frame first before calling plotCoef, e.g., plotCoef(subset(coef(fit), Time > 2 & Time < 10)).
