Dataset metadata can be valuable, eg. by tracing an archived dataset back to the code that generated it. The metadata added by NMstamp can be accessed using the function NMinfo.

NMstamp(data, script, time = Sys.time(), ...)

Arguments

data

The dataset to stamp.

script

path to the script where the dataset was generated.

time

the time stamp to attach. Default is to use cpu clock.

...

other named metadata elements to add to the dataset. Example: Description="PK data for phase 1 trials in project".

Value

data with meta data attached. Class unchanged.

Details

NMstamp modifies the meta data by reference. See example.
