This article mainly explains "how to solve pheatmap NA/NaN/Inf clustering errors". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to solve pheatmap NA/NaN/Inf clustering errors.

The error message in the pheatmap drawing is similar to:

Error in hclust (d, method = method): NA/NaN/Inf (arg11) is not allowed when an external function is called

This type of error occurs in most cases when the NA/NaN/Inf occurs after the data is processed during the drawing process, which makes it impossible to cluster.

One is that there is NA in the original data, and the other is that there is no change in the original data, but the scale parameter is selected in the pheatmap () function. For example, if the value of one of the genes (row) does not change at all, the external transfer of hclust will not be successful after scale processing will produce NaN.

> scale (A) [, 1] [1,] NaN [2,] NaN [3,] NaN [4,] NaN [5,] NaN [6,] NaN [7,] NaNattr (, "scaled:center") [1] 1attr "scaled:scale") [1] 0 > hclust (scale (A)) Error in if (is.na (n) | | n > 65536L) stop ("size cannot be NA nor exceed 65536"): missing value where TRUE/FALSE needed so far I believe you have a deeper understanding of "how to solve pheatmap NA/NaN/Inf clustering errors".
