modFilter
imposes a hard filter for (gene expression) feature data.
modFilter(object, threshold, maximum, beta1, beta2, plotSkip = TRUE)
"modFilter"(object, threshold, maximum, beta1, beta2, plotSkip = TRUE)

object.
threshold
to threshold
and all values greater than maximum
to maximum
.Next, this method includes only those features with (a) a range greater
than beta1
, and also (b) a ratio of maximum feature expression to
minimum feature expression greater than beta2
.
