Since you've established that it is "ln", you need to STOP using "In". It is NOT "In".what is this "In" function called(full form), so that i could search to learn more about it,
The formula you posted is fundamentally flawed because, as I stated before, R has units and the argument to the natural log function, like the arguments to all trascendental functions, must be dimensionless.Are you sure it isn't "ln" (lower case L)? If so, then that is the natural logarithm function.
