There are a lot of machine learning options in R:

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:

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