library(corrplot)  
    library(viridis) 

    col4 <- viridis_pal()(dim(cor_matrix)[2]) 

    filetag <- "corrplot_result.png" 
    png(filetag, height = 800, width = 800) 

     par(oma = c(0, 2, 2, 2)) 
     corrplot.mixed(cor_matrix, order = "AOE", upper = "ellipse", lower = "number", 
        upper.col = col4, lower.col = col4, 
        tl.cex = 1.5, cl.cex = 1.5)
