Trace of a variable
Description
This function returns and plots a complete trace for a variable.
Usage
samplesHistory(node, beg = samplesGetBeg(), end = samplesGetEnd(),
firstChain = samplesGetFirstChain(),
lastChain = samplesGetLastChain(), thin = samplesGetThin(),
plot = TRUE, mfrow = c(3, 1), ask = NULL, ann = TRUE, ...)
Arguments
node |
Character vector of length 1, name of a variable in the model. |
beg , end |
Arguments to select a slice of monitored values corresponding to iterations |
firstChain , lastChain |
Arguments to select a sub group of chains to plot the trace for. |
thin |
to only use every |
plot |
Logical, whether to plot the trace or only return the values.
If |
mfrow , ask , ann |

Details
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.
Value
A list containing matrices - one for each scalar variable contained in
argument node
. Each row of a matrix corresponds to one chain.
