maCompPlate {marray} | R Documentation |
This function generates plate IDs from the dimensions of the grid and spot matrices. Note that this function only applies to arrays with a regular plate layout, where the number of spots is a multiple of the number of wells on a plate (usually 96 or 384) and each well contributes exactly one spot. It should thus be used with caution.
maCompPlate(x, n=384)
x |
object of class "marrayLayout" ,
"marrayRaw" and "marrayNorm" |
n |
object of class "numeric", number of wells in each plate, usually 384 or 96. |
Having plate IDs may be useful for the purpose of
normalization. Normalization by plate can be done using the function
maNormMain
.
a vector of plate IDs (factor
).
