access help files for functions

[mikeyEcology]

Thank you for creating the rTorch package. This will be a great way to make neural networks accessible to the many scientists who use R but not Python.
I'm wondering if/how I can access help files for functions not listed in the manual provided on cran. The functions in this package are accessed similarly to Python, which is different from how typical R functions work, so I'm having trouble finding out exactly what arguments are available for each function. Here is an example from here.

library(rTorch) # (after setting up conda environment)
N <- 64L; D_in <- 1000L
device = torch$device('cpu')
x <- torch$randn(N, D_in, device=device)

I'm wondering how can I find documentation for the function randn; this would typically done in R via ?torch$randn, but R does not allow this. I could go into python and type help(torch.randn) to access the documentation, but I'm wondering if there is a better way in R.
