? Can you please provide a REPRoducible EXample of your problem? It provides more specifics of your problem, and it helps others to understand what problem you are facing.

If you don't know how to do it, take a look at this thread:

I tried with `iris`

, and the results seem to be fine.

```
library(cluster)
Dist <- daisy(x = iris,
metric = "gower")
Dist_mat <- as.matrix(x = Dist)
image(x = Dist_mat)
```

```
image(x = 1:nrow(x = Dist_mat),
y = 1:ncol(x = Dist_mat),
z = Dist_mat,
axes = FALSE,
xlab = "",
ylab = "",
col = rainbow(n = 100))
```
