plotSplom {scapeMCMC} | R Documentation |
Plot scatterplots of multiple Markov-chain Monte Carlo chains. This is a diagnostic plot for deciding whether parameters are confounded. When parameter estimates are highly dependent on each other, it may undermine conclusions based on MCMC results of that model.
plotSplom(mcmc, axes=FALSE, between=0, div=1, log=FALSE, base=10, ...)
mcmc |
MCMC chains as a data frame or mcmc object. |
axes |
whether axis values should be plotted. |
between |
space between panels. |
div |
denominator to shorten values on the y axis. |
log |
whether values should be log-transformed. |
base |
logarithm base. |
... |
passed to pairs() . |
Null, but a plot is drawn on the current graphics device.
The Args
function from the gdata package is recommended
for reviewing the arguments, instead of args
