Anyone familiar with R tool?

Hi Guys,

How many here in this group are familiar with R tool?

Asking this, because I would like to know & understand whether the following techniques are carried out in R tool or not as enlisted below:—

a) Hyperparameters
b) Regularization
c) Creating Pipelines
d) Cost Functions & Optimization

I can see these topics being carried out on a large-scale in Python. But never come across these concepts in R tool.

If any members of Cloud X community are aware about these concepts, kindly let me know. I believe such topics would definitely be asked in the interviews and acquiring knowledge about it is important.

Would be eager to discuss these topics for better understanding and for mutual exchange of knowledge.
