samplesHistory {BRugs} | R Documentation |
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, ...)
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 beg:end . |
firstChain, lastChain |
Arguments to select a sub group of chains to plot the trace for. |
thin |
to only use every thin -th value of the stored sample for statistics. |
plot |
Logical, whether to plot the trace or only return the values.
If TRUE , values are returned invisibly. |
mfrow, ask, ann |
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.
A list containing matrices - one for each scalar variable contained in
argument node
. Each row of a matrix corresponds to one chain.
