Arguments

process	a character string defining the name of the process.
envir	the frame in S-PLUS (or environment in R) designated for the processing and storage of pipeline history data. Default: msProcessEnv, a global environment impicitly set by a previous call to throwEvent. In general, the user should rely on the specified default value.

## verify process has been recorded: TRUE 
isProcessRecorded(process)
