Hello Ching Yew- The data for the vignette can be found at this link: https://www.dropbox.com/s/bqxnqhvr7sol1za/DiffBindVignette.zip If you unzip this and make the unzipped directory your current directory, instead of system.file("extra", package="DiffBind"), the vognette should run, including the call to dba.count.
