    Thanks for the video Sir. I have to use a colorRampPalette to see colors on the plot.
    corrplot (Time, method = "color", col = colorRampPalette(c("blue", "white", "red"))(200),
    type = "upper", order = "hclust", addCoef.col = "black",
    tl.col = "black", tl.srt = 45, diag = FALSE)

    Thank you very much, I am a big fan of R and wanted to use it for quite long. Your this video made things very easy. However, it would be so nice of you, if you let me know how to highlight significant values in correlation and the confidence level (eg 99.99% or 95%). Secondly, do you have any video on PCA/FA and Cluster Analysis in R using water quality data?

      I am using the code you developed, however, I just want to add the significant values or star on in final diagram. The code is given below.
      > corrplot(m, method=“color”, col = col(200), type = “upper”, order= “hclust”, addCoef.col = “black”, tl.col = “black”, tl.srt = 45, diag = FALSE)

      @@softwaresforcivilengineeri7947 similarly, used your code for box wicker plots and it worked well. However, can you help to show the box plots using logarithmic y axis. Because in my case some of values are too small and some other too large and box plots with small cant be seen properly. The log scale can solve this issue

      correlation_matrix is basically my data name. if you have the data in excel format. just upload it to R in the same manner. and you can give it the name correlation matrix.

      @softwaresforcivilengineeri7947  3 года назад

      when you do not mention the type of correlation to R. it will take Pearson correlation by default. But if you want to draw another type of correlation, then you need to mention that type. the only difference is in the formula. if you want the detail I will share them with you.
