Matrix rendering much faster when NOT using the shiny wrapper

[katsikora]

Hi,

we've noticed the matrix rendering (say matrix(rnorm(200000), 10000)) is very slow using morpheus(x) in shiny, but rendering from a text file opened via what looks like a morpheus iframe or API on the shiny-rendered page is instantenous.

Why's that? Is there anything we can do to speed things up when using the shiny wrapper?

Thanks for any advice,

Best,

Katarzyna

else if (! isTRUE(Rowv)) {
rowInd <- nr : 1
ddr <- as.dendrogram(hclust(dist(diag(nr))))
}

This looks like a slow process.

Is it possible to set rowDendrogram <-NULL directly if dendrogram="none" is specified ? And skip ddr computation.

Best,

Katarzyna

You can set Rowv to FALSE
