Arguments

x	Input matrix.
Rowv	Logical or dendrogram. If Logical: Compute dendrogram and reorder rows. Defaults to FALSE. If dendrogram: use as is, without reordering. See more at heatmaply::heatmaply("Rowv").
Colv	Logical or dendrogram. If Logical: Compute dendrogram and reorder columns. Defaults to FALSE. If dendrogram: use as is, without reordering. See more at heatmaply::heatmaply("Colv").
cluster	Logical: If TRUE, set Rowv and Colv to TRUE.
symm	Logical: If TRUE, treat x symmetrically - x must be a square matrix.
cellnote	Matrix with values to be displayed on hover. Defaults to ddSci(x).
colorgrad_n	Integer: Number of colors in gradient. Default = 101.
colors	Character vector: Colors to use in gradient.
space	Character: Color space to use. Default = "rgb".
lo	Character: Color for low values. Default = "#18A3AC".
lomid	Character: Color for low-mid values.
mid	Character: Color for mid values.
midhi	Character: Color for mid-high values.
hi	Character: Color for high values. Default = "#F48024".
k_row	Integer: Number of desired number of groups by which to color dendrogram branches in the rows. Default = 1.
k_col	Integer: Number of desired number of groups by which to color dendrogram branches in the columns. Default = 1.
grid_gap	Integer: Space between cells. Default = 0 (no space).
limits	Float, length 2: Determine color range. Default = NULL, which automatically centers values around 0.
margins	Float, length 4: Heatmap margins.
main	Character: Main title.
xlab	Character: x-axis label.
ylab	Character: y-axis label.
key_title	Character: Title for the color key.
showticklabels	Logical: If TRUE, show tick labels.
colorbar_len	Numeric: Length of the colorbar.
plot_method	Character: Plot method to use. Default = "plotly".
theme	Theme object.
row_side_colors	Data frame: Column names will be label names, cells should be label colors. See heatmaply::heatmaply("row_side_colors").
row_side_palette	Color palette function. See heatmaply::heatmaply("row_side_palette").
col_side_colors	Data frame: Column names will be label names, cells should be label colors. See heatmaply::heatmaply("col_side_colors").
col_side_palette	Color palette function. See heatmaply::heatmaply("col_side_palette").
font_size	Numeric: Font size.
padding	Numeric: Padding between cells.
displayModeBar	Logical: If TRUE, display the plotly mode bar.
modeBar_file_format	Character: File format for image exports from the mode bar.
filename	Character: File name to save the plot.
file_width	Numeric: Width of exported image.
file_height	Numeric: Height of exported image.
file_scale	Numeric: Scale of exported image.
...	Additional arguments to be passed to heatmaply::heatmaply.
