bugs2jags: Convert WinBUGS data file to JAGS data file

Description Usage Arguments Note Author(s) References See Also

View source: R/jags.R


bugs2jags converts a WinBUGS data in the format called "S-Plus" (i.e. the format created by the dput function) and writes it in dump format used by JAGS.

NB WinBUGS stores its arrays in row order. This is different from R and JAGS which both store arrays in column order. This difference is taken into account by bugs2jags which will automatically reorder the data in arrays, without changing the dimension.

Not yet available in S-PLUS.


bugs2jags(infile, outfile)



name of the input file


name of the output file


If the input file is saved from WinBUGS, it must be saved in plain text format. The default format for files saved from WinBUGS is a binary compound document format (with extension odc) that cannot be read by bugs2jags.
