Logarithm With Thresholding
Description
Safe log and log2 calculations where values within [0, thresh) are
thresholded to thresh prior to the transformation.
Usage
logt(x, thresh = 0.5)
log2t(x, thresh = 0.5)
Arguments
x
a numeric or complex vector.
thresh
a positive number specifying the threshold.
Details
For non-negative elements in x, calculates log(pmax(x, thresh))
or log2(pmax(x, thresh)).
Value
A vector of the same length as x containing the transformed values.
