Hello, can someone tell me how to find the harmonic number in R. I know how to find it on Wolfram Mathematica using command HarmonicNumber[n]. for eg, HarmonicNumber[-(3/4)]. But I don't know how to find it on R. I don't know which package or command should be used.

I know just enough math and also just enough r to give you the implementation of the common definition

as seen here:

the n-th

harmonic numberis the sum of the reciprocals of the first n natural numbers

Harmonic number - Wikipedia

```
harmonicnumber <- function(n){
k <- seq_len(n)
-sum((-1)^k*(1/k) * choose(n,k))
}
```

This doesn't cover -3/4 as that is not a natural number

Oh I see. Thank you so much ya.
