Hi all,
I am working on PCA analysis and am wondering how to format the figure? For example, I use the code below to plot the figure, as shown below. How to edit the x and y axis titles? For example, I want x-axis to be PC1 instead of Dim1 (41.%), how to realize this? Second, how to remove the background grids and use a rectangular box? Thanks for your help.
I have another question regarding to this problem.
If I use the code below to create a PCA plot of PC3~PC4, and get the figure. How to put the two figures in one panel in R directly? Thanks again.
