Description Usage Arguments Value
Implements local background correction for peptide microarray data
1 2 3 4 5 | arrayBGcorr(x, ...)
## S4 method for signature 'MultiSet'
arrayBGcorr(x, method = "none", offset = 1,
transform = "log2", ...)
|
x |
MultiSet object with fMedian and bMedian matrices in the assayData slot |
method |
Character string specifying background correction method. Valid methods are 'none', 'subtract', 'edwards', ratio' or 'normexp'. Defaults to 'none' if no method is specified. |
offset |
numeric value added to raw signal intensity before background correction is implemented |
transform |
Expression to transform raw data. Defaults to log2 |
MultiSet object with transformed and background corrected foreground signal in the fMedian matrix
