I am a new user of Rsudio, and I need some help.
I doing a work with data from six countries (for 3 months), and seven variables for study as: manufacturing Energy, Capital goods...
My teacher compels us to use the "Statis" and "prcomp" functions.
Then we have to reserch new "Packages" for graphics and PCA analysis to cross data
For the moment I already found a difficulty. I use "biplot" and "epPCA" for comparing and with these two I find solutions differents. it is as if the graph is inverted relative to the point center of the axes
I do not know what I'm doing wrong or if this situation can happen and have solution!
I would like some tips from the community for solve this problem, and ask for new packages/functions that i can use to improve my study,
Thank you in advance for your attention.
Greetings for all
