Issue with R package pheatmap

[ovancantfort]

I am encoutering an issue when publishing a R visual.

The package pheatmap is listed as supported 

However, when publishing a script using pheatmap, it fails to render online and gives following error

Here is some minimum code that reproduce the error:

# The following code to create a dataframe and remove duplicated rows is always executed and acts as a preamble for your script: 

# dataset <- data.frame(DAta)
# dataset <- unique(dataset)

# Paste or type your script code here:
mat <- matrix(c(0,1,1,0.3), nrow = 2, ncol = 2)
library(pheatmap)
pheatmap(mat)

Replacing the last command with base R heatmap(mat) executes properly. So, it shows the library pheatmap loads properly, but the command fails to execute. Most probably some dependencies are missing on the backend.
