qcplate(dat, s0="S0", s1="S1", poscont="Control P",
 negcont="Control N", qc1.val=0.225, qc2.val=2, addcont, welltype="welltype")

Arguments

dat
s0

Specifies the name of the columns containing t0-specific scores.

s1

Specifies the name of the columns containing t1-specific scores.

poscont

Specifies positive control designation (used in C-score normalization).

negcont

Specifies negative control designation (used in C-score normalization).

qc1.val

Pre-defined threshold value for QC1.

qc2.val

Pre-defined threshold value for QC2.

addcont

A vector character names specifying the additional controls for QC3. The vignette provides more details on the particular order of specifying the additional controls.

welltype

Specifies the name for the column defining the well type.
