log2t {NanoStringNCTools} | R Documentation |
Safe log and log2 calculations where values within [0, thresh) are thresholded to thresh prior to the transformation.
logt(x, thresh = 0.5) log2t(x, thresh = 0.5)
x |
a numeric or complex vector. |
thresh |
a positive number specifying the threshold. |
For non-negative elements in x
, calculates log(pmax(x, thresh))
or log2(pmax(x, thresh))
.
A vector of the same length as x
containing the transformed values.
