Can you draw only a few variables and color them?
Yes we can in multiple ways but I am not sure what do you mean by it. Could you please be more elaborating.
Hi! Welcome to RStudio Community!
Ideally you'd give us a reproducible example (reprex) of your issue as a starting point. A reprex makes it much easier for others to understand your issue and figure out how to help. A lack of a reprex just makes it much less likely others will reply.
reprex typically includes a toy data set, the code you have tried, any error messages you are getting, and your desired output.
