R version 3.5.1. I want to create a correlation matrix with a Data frame that goes like this:
BGI WINDSPEED SLOPE
4277.2 4.23 7.54
4139.8 5.25 8.63
4652.9 3.59 6.54
3942.6 4.42 10.05
I put that as an example but I have more than 20 columns and over 40,000 entries.
I tried using the following codes
corrplot(cor(Site.2),method = "color",outline="white")
Matrix_Site=cor(Site.2,method=c("spearman"))
but every time, the same warning appears:
Error in cor(Site.2) : 'x' must be numeric
I would like to correlate every variable of the data frame with each other and create a graph and a table with it, similar to this.
