Load samples from a file-backed MCMC run
Description
LoadMcmc
loads the samples from a file-backed MCMC run initiated by
InitMcmc
. The result is a list of big.matrix
with all
of the parameters that were saved in the MCMC run. Alternatively, the
samples for individual parameters can be loaded by using
attach.big.matrix
to load the corresponding descriptor
file, "ParameterName.desc," in the MCMC's backing.path
directory.
Usage
LoadMcmc(backing.path)
Arguments
backing.path |
directory path where MCMC samples were saved |
Value
list of big.matrix
with the MCMC samples

Examples
# Run a file-backed MCMC
backing.path <- tempfile()
dir.create(backing.path)
Mcmc <- InitMcmc(1000, backing.path=backing.path)
samples <- Mcmc({
x <- rnorm(1)
})
rm(samples)
# Load the saved samples
loaded.samples <- LoadMcmc(backing.path)
hist(loaded.samples$x[,], main="Samples", xlab="x")
