samplesAutoC | R Documentation |
This function calculates and plots the autocorrelation function of a variable.
samplesAutoC(node, chain, beg = samplesGetBeg(),
end = samplesGetEnd(), thin = samplesGetThin(), plot = TRUE,
mfrow = c(3, 2), ask = NULL, ann = TRUE, ...)
node |
Character vector of length 1, name of a variable in the model. |
chain |
Selects a chain to plot autocorrelation function for. |
beg , end |
Arguments to select a slice of monitored values corresponding to iterations |
thin |
To only use every |
plot |
Logical, whether to plot the ACF or only return the values. If |
mfrow , ask , ann |

If the variable of interest is an array, slices of the array can be selected using the notation
variable[lower0:upper0, lower1:upper1, ...]
.
A star ‘*
’ can be entered as shorthand for all the stored samples.
If the arguments are left at their defaults the whole sample for all chains will be used for calculation.
A list containing acf
objects - one for each scalar variable contained in
argument node
. See acf
for details on the list elements.
If the MCMC simulation has an adaptive phase it will not be possible to make inference using values sampled before the end of this phase.
