Zeros happen. Logging zeros leads to errors in downstream code. For the sake of robustness, we replace zeros with a small positive number to be able to continue with calculations.
rlog(x, base = exp(1))
| x | numeric or complex vector. |
|---|---|
| base | positive or complex number. The base with respect to which
logarithms are computed. Defaults to |
Use judiciously, since errors are good too.
