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?
@@softwaresforcivilengineeri7947 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
Hlo sir, i have query regarding the last script. What is the meaning of col (200) and on what basis i have fill this number in col and similar problem in tl.srt = 45 .. what does it mean
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.
nice video very useful but i got this following error how to solve corrplot(m,method = "color",col(200),type = "upper", order = "hclust", addCoef.col = "black", tl.col = "black", tl.srt = 45, diag = FALSE) Error in col(200) : a matrix-like object is required as argument to 'col'

Nice. I successfully create the circle, number, and pie. But, the last one the upper triangle; it did not work by showing : Error in col(200) : a matrix-like object is required as argument to 'col'. Kindly help
@@daveandrew Thank you for your comments, first please save the col(200) type with a unique variable e.g "colour=col(200) and then run the above code. Also install the concerned packages used for colors.
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.
Hello. Thanks for your great video. When I tried the code for upper matrix type, I got this error: Error in col(200) : a matrix-like object is required as argument to 'col' Would you please help me figure out the reason?
Sir, first of all I'd like to thank you for this correlation matrix video. It has been really usefull. Please help me with the following error: > cor(dados, method = "spearman") #"dados" is my data name Error in cor(dados, method = "spearman") : 'x' must be numeric
Please arrange your data. i think your data have some non numeric values. All the rows and columns of the data must be numeric. if then you face the problem please share your data.

Thank you Sir for your nice tutorial. How can I put asterisk (***) in the method argument instead of number please?
how can we combine summary of statistics and correlation plot in one diagram. thanx
Aselamua'leyikum werahmetulah, I ahve sort of data would you help me by analysing the correlation between variables by using R software

Please tell me in which condition we use Pearson, spearman,and Kendall correlation?

When should you use Pearson, Spearman or other?

Would you please help me figure out the reason?
col(200) needed another package to install. just remove this col(200). or install package for colors in R.
Kindly tell how to install package for colors in R
Even after deleting Col(200) some error is showing kindly help to get through it
Nice one thanks
Please share video on lag1 auto-corellation
