could not find function "AlphaShapeDiag"

[KiranTen63]

Hi, I am new to R, so apologies if there is a very obvious solution that I should have known. I installed this package using the devtools install_github function, for R version 4.0.4 on Ubuntu 20.04.2 LTS. When I try to run the following code, I get an error saying that the AlphaShapeDiag function could not be found. Is this function meant to be called recursively and this is just a typo in the first letter? Or am I potentially missing some dependencies?

> library("TDA")
> X = read.csv("/test.csv")

> print(X)
      x1     x2     x3

2 33.920 23.170 26.040
3 32.629 22.586 25.382
