I tried to create a subplot with big numbers. A simplified example: the following code which creates 19 empty plots works fine.

> plotList ← function(nplots) {lapply(seq\_len(nplots), function(x) plot\_ly())}  
> subplot(plotList(19), nrows = 19, shareX = TRUE, shareY = TRUE)

However, it goes wrong if the number of plots exceeds 20.

> subplot(plotList(21), nrows = 21, shareX = TRUE, shareY = TRUE)

Is there a way to solve it?
