If I do understand this is what you are looking for :
plot(x, choices = c(1, 2), display = c("sp", "wa", "cn"),
scaling = 2, type, xlim, ylim, const, ...)
The option choices helps you to select the axis. In your case it would
be choices = c(1,3) [axis 1 vs 3] or choices = c(2,3) [axis
Hello,
I am using the VEGAN package to do PCA of my variables.
bio.pca <- rda(variables, scale=TRUE) # Argument scale=TRUE
bio.pca
summary(bio.pca) # Default scaling 2
summary(bio.pca, scaling=2)
sum_bio <-summary(bio.pca)
names(sum_bio)
sum_bio$species
#make basic plot
Thank you very much!
Regards,
Lara
