2.Perform a Univariate, Multivariate or Regression Analysis. For this project, I will perform a multivariate analysis using the "iris data set". Specifically, I will use principal component analysis (PCA) to reduce the dimensionality of the data and visualize the samples in a two-dimensional space. Please can you provide the R code you used in doing this multivariate analysis. I do not see it here. Thank you very much.
