## R: Logarithms and Exponentials

http://astrostatistics.psu.edu/su07/R/html/base/html/Log.html

Details. exp and log are generic functions: methods can be defined for them individually or via the Math group generic.. log10 and log2 are only special cases, but will be computed more efficiently and accurately where supported by the OS.. Value. A vector of the same length as x containing the transformed values.log(0) gives -Inf (when available). Note. log and logb are the same thing in R …

## Log function in R – log() – DataScience Made Simple

Log function in R –log() computes the natural logarithms (Ln) for a number or vector. Apart from log() function, R also has log10 and log2 functions. log10 function –log10(), computes common logarithms (i.e. …

In R, log is the natural logarithm. In calculators, log usually means base 10 logarithm. To achieve that in R you can use the log10 function. log(5) ##  1.609438 log10 ##  0.69897(5) As for your formula, it seems correct, since log is the natural logarithm.

logb is a wrapper for log for compatibility with S. If (S3 or S4) methods are set for log they will be dispatched. Do not set S4 methods on logb itself. All except log are primitive functions. Value. A vector of the same length as x containing the transformed values. log(0) gives -Inf, and log(x) for negative values of x is NaN. exp(-Inf) is 0.

## log function R Documentation

log(0) gives -Inf, and log(x) for negative values of x is NaN. exp(-Inf) is 0. For complex inputs to the log functions, the value is a complex number with imaginary part in the range $$[-\pi, \pi]$$: which end of the range is used might be platform-specific.

Built-in Functions . Almost everything in R is done through functions. Here I'm only refering to numeric and character functions that are commonly used in creating or recoding variables. (To practice working with functions, try the functions sections of this this interactive course.) Numeric Functions
