Pheatmap x must be numeric

Question

[Hamza]

I receive the following error from pheatmap:

pheatmap(my_matrix,annotation_col = my_metadata)
Error in cut.default(a, breaks = 100) : 'x' must be numeric

However, my matrix is already numeric

apply(my_matrix,2,is.numeric)

          TRUE

So I don't understand the issue. Can anyone take a guess?

class(my_matrix)
[1] "matrix, array"

My matrix looks like this

Please try as.matrix(my_matrix) or data.matrix(my_matrix). Also, please ensure that the colnames of my_matrix are the same as the rownames of my_metadata
