Thanks mate, this video is excellent! 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!
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)),
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.
@@AGRONInfoTech My data it is the concentration of a group of chemical elements in the water, such as Ca, Mg, Na, Hco3 .... for a group of well samples, which represent lines
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?!

(rep)

rep(17, times = 100)),

You need not to use rep argument if don't have repeated experimental units
@@AGRONInfoTech Thnak you , I want said now tha package ggbiplot it don't install because my R vergion 4.03
How to solve this problem please
What error it shows. Try to install package in older version then the one mentioned in error message

Can you share your data and R script?
You can share at agron.infotech@gmail.com
How make a PCA with three components?
Did you mean biplot for three components?
Make separate biplots:
PC1 vs PC2
PC2 vs PC3
Or PC1 vs PC3
