[R] machine learning goal (new to R )

[Sarah Goslee]

There are a lot of machine learning options in R:
https://cran.r-project.org/web/views/MachineLearning.html

It sounds like you need to back up a step, and do some reading on the
statistical underpinnings of machine learning before you try to figure
out how to implement a particular method.

There are an enormous number of references online, from brief articles
to full courses. Here's one possible starting point:
https://statweb.stanford.edu/~tibs/ElemStatLearn/

The options are far too complex and numerous for anyone here to be
able to tell you the "right method" to use.
