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!
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)),
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
Thank you so much for this wonderful video. Was waiting for this.. u r an angel

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)),

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
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
