• logTrafo
Natural logarithm.

• sqrtTrafo
Square root.

If negative values occur and the trafo function can handle only positive values, a shift of the form x - min(x) + 1 is performed prior to the transformation if the argument handle.violations is set to “warn” which is the default value.

trafoLog(base = 10, handle.violations = "warn")

trafoSqrt(handle.violations = "warn")

## Arguments

base [numeric(1)] The base with respect to which logarithms are computed. Default is 10. [character(1)] What should be done, if negative values occur? Setting this option to “warn”, which is the default, shifts the function. “error” stops the process immediately.
