I want to use PCA and t-SNE to achieve the desired result!

Current situation: I typed the PCA script into paiza(beta), but the following error occurred and I couldn't run it.

File "Main.py", line 6
d_pca<-prcomp(coil20[,-ncol(coil20)], scale=TRUE)
^
SyntaxError: invalid syntax

Final Objective: We would like to get results as shown in the link below.*The desired image is also included in this question.

I will write down the current state in an image so that it is easy to understand.

The final image is as follows.
