Read data for a JAGS model from a file.
read.jagsdata(file)
read.bugsdata(file)name of a file containing a text repesentation of the data for a jags model
A named list of numeric vectors or arrays.
The command line interface for JAGS reads data and initial values from
a text file. The data format used for jags data files is the same as the R
dump function. Thus the data values can be read into an
R session using the source function, but this will create
objects in the global environment. The read.jagsdata function
is a simple wrapper that reads the data into a list instead.
OpenBUGS also reads data and initial values from a text file. The
format of these files is described as "S-PLUS" format by the OpenBUGS
authors. It superficially resembles the format used by the dput
function (and in fact can be parsed by the dget
function). However, in BUGS "S-PLUS" format, arrays are stored in
row-major order instead of the column-major order used by R. The
read.bugsdata function reads OpenBUGS "S-PLUS" format files and
permutes the elements of arrays so that they appear in the correct
order.
Either function returns a list which can be used as the
data or inits argument of jags.model.
