set_nd() set_nd_focus()
|
Set non-detects in residue series without replicates
Sets non-detects directly before or directly after detects to NA. Values between
lod and loq are set to their mean value if an loq is specified.
If 'time_zero' is set to TRUE, the residue series is assumed to start with time
zero, and non-detects at time zero are set to 'time_zero_nd_value'. For the
set_nd_focus variant, this is zero, otherwise this argument has NA as default
value.
If stopping after the first non-detection is requested, as in in the FOCUS
variant of the function, an loq has to be specified in order to decide
if any later detections are above the loq. |
