This function uses Hampel filter outlier detection to flag
outliers in parameter
column of the incoming dataframe. The
windowSize
and thresholdMin
parameters as passed on to the
seismicRoll::findOutliers
function.
An additional boolean column named <parameter>_outlierFlag
is added
to the dataframe. This column will have TRUE
whenever an outlier is
detected for the chosen parameter
.
See seismicRoll::findOutliers
for further details.
