    Any chance you can add some suggestions for the easiest way to export/save this plot as a high-resolution jpeg/png/tiff file?
    Many thanks!

    Please answer to me, after following your steps, in my PCA result I get a very small sized polygon, the plygon not cover the individual in each group. How can I fix that problem?!

    Thank you sir , please answer for my question
    When using chemical analyzes data for water what do we put in place
    (rep)
    pch = c(rep(16, times = 100),
    rep(17, times = 100)),

    • @AGRONInfoTech
      @AGRONInfoTech  4 ปีที่แล้ว +1

      Here rep is indicating how many times a symbol of type 16 and 17 would be repeated. In my case 100 obs were representing genuine and next hundred counterfeit bank notes. I am not sure what is structure of your data.

    How make a PCA with three components?

    • @AGRONInfoTech
      @AGRONInfoTech  4 ปีที่แล้ว

      Did you mean biplot for three components?
      Make separate biplots:
      PC1 vs PC2
      PC2 vs PC3
      Or PC1 vs PC3
