exprsToRatios-methods {MSnbase} | R Documentation |
Calculations all possible ratios for the assayData
columns in
an "MSnSet"
. The function
getRatios(x, log = FALSE)
takes a matrix x
as input and
is used by exprsToRatios
.
signature(object = "MSnSet", log = "logical")
If log
is FALSE (default) the ratios for all the
assayData
columns are computed; otherwise, log ratios
(differences) are calculated.
signature(object = "matrix", log = "logical")
As above, but for a matrix
instance.
