visW {DrBats}R Documentation

Plot the estimates for the latent factors

Description

Plot the estimates for the latent factors

Usage

visW(mcmc.output, Y, D, chain = 1, factors = c(1, 2))

Arguments

mcmc.output

an mcmc list as produced by clean.mcmc

Y

the matrix of data

D

the number of latent factors

chain

the chain to plot (default = 1)

factors

a vector indicating the factors to plot (default = c(1, 2))

Value

res.W a data frame containing the estimates for the factors, and their lower and upper bounds

Inertia the percentage of total inertia captured by each of the factors

Examples

data("toydata")
data("stanfit")
codafit <- coda.obj(stanfit) ## convert to mcmc.list
W.res <- visW(codafit, Y = toydata$Y.simul$Y, D = toydata$wlu$D,
chain = 1, factors = c(1, 2))

## plot the results

data <- data.frame(time = rep(1:9, 2), W.res$res.W)
ggplot2::ggplot() +
  ggplot2::geom_step(data = data, ggplot2::aes(x = time, y = Estimation, colour = Factor)) +
  ggplot2::geom_step(data = data, ggplot2::aes(x = time, y = Lower.est, colour = Factor),
  linetype = "longdash") +
  ggplot2::geom_step(data = data, ggplot2::aes(x = time, y = Upper.est, colour = Factor),
  linetype = "longdash")
