Plot coefficient values formatted in a data frame returned by
function coef.
Usage
plotCoef(object, smooth=FALSE, ...)
Arguments
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.
Value
A ggplot object.
Details
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)).
