This function returns and plots a complete trace for a variable.
samplesHistory(node, beg = samplesGetBeg(), end = samplesGetEnd(),
firstChain = samplesGetFirstChain(),
lastChain = samplesGetLastChain(), thin = samplesGetThin(),
plot = TRUE, mfrow = c(3, 1), ask = NULL, ann = TRUE, ...)
A list containing matrices - one for each scalar variable contained in
argument node
. Each row of a matrix corresponds to one chain.
Character vector of length 1, name of a variable in the model.
Arguments to select a slice of monitored values corresponding to iterations beg:end
.
Arguments to select a sub group of chains to plot the trace for.
to only use every thin
-th value of the stored sample for statistics.
Logical, whether to plot the trace or only return the values.
If TRUE
, values are returned invisibly.
Graphical parameters, see par
for details.
ask
defaults to TRUE
unless it is plotting into an already opened non-interactive device.
The ann
parameter is not available in S-PLUS, and will be ignored if it is set.
Further graphical parameters as in par
may also be passed as arguments
to plotHistory
.
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.
