Arguments

sample	Seurat | A Seurat object, generated by CreateSeuratObject.
features	character | Features to represent.
slot	character | Data slot to use. Only one of: counts, data, scale.data. Defaults to "data".
dims	numeric | Vector of 2 numerics indicating the dimensions to plot out of the selected reduction. Defaults to c(1, 2) if not specified.
pt.size	numeric | Size of the dots.
reduction	character | Reduction to use. Can be the canonical ones such as "umap", "pca", or any custom ones, such as "diffusion". If you are unsure about which reductions you have, use Seurat::Reductions(sample). Defaults to "umap" if present or to the last computed reduction if the argument is not provided.
combine	logical | Whether to create a single plot out of multiple features.
method	Kernel density estimation method: ks: Computes density using the kde function from the ks package. wkde: Computes density using a modified version of the kde2d function from the MASS package to allow weights. Bandwidth selection from the ks package is used instead.
joint	logical | Whether to plot different features as joint density.
return_only_joint	logical | Whether to only return the joint density panel.
plot.title, plot.subtitle, plot.caption	character | Title, subtitle or caption to use in the plot.
legend.type	character | Type of legend to display. One of: normal: Default legend displayed by ggplot2. colorbar: Redefined colorbar legend, using guide_colorbar.
legend.framewidth, legend.tickwidth	numeric | Width of the lines of the box in the legend.
legend.length, legend.width	numeric | Length and width of the legend. Will adjust automatically depending on legend side.
legend.framecolor	character | Color of the lines of the box in the legend.
legend.tickcolor	character | Color of the ticks of the box in the legend.
font.size	numeric | Overall font size of the plot. All plot elements will have a size relationship with this font size.
font.type	character | Base font family for the plot. One of: mono: Mono spaced font. serif: Serif font family. sans: Default font family.
legend.position	character | Position of the legend in the plot. One of: top: Top of the figure. bottom: Bottom of the figure. left: Left of the figure. right: Right of the figure. none: No legend is displayed.
plot_cell_borders	logical | Whether to plot border around cells.
border.size	numeric | Width of the border of the cells.
border.color	character | Color for the border of the heatmap body.
viridis.palette	character | A capital letter from A to H or the scale name as in scale_fill_viridis.
viridis.direction	numeric | Either 1 or -1. Controls how the gradient of viridis scale is formed.
verbose	logical | Whether to show extra comments, warnings,etc.
na.value	character | Color value for NA.
plot.axes	logical | Whether to plot axes or not.
number.breaks	numeric | Controls the number of breaks in continuous color scales of ggplot2-based plots.
use_viridis	logical | Whether to use viridis color scales.
sequential.palette	character | Type of sequential color palette to use. Out of the sequential palettes defined in brewer.pal.
sequential.direction	numeric | Direction of the sequential color scale. Either 1 or -1.
plot.title.face, plot.subtitle.face, plot.caption.face, axis.title.face, axis.text.face, legend.title.face, legend.text.face	character | Controls the style of the font for the corresponding theme element. One of: plain: For normal text. italic: For text in itallic. bold: For text in bold. bold.italic: For text both in itallic and bold.

Value

A ggplot2 object containing a Nebulosa plot.
