Arguments

sample

Seurat | A Seurat object, generated by CreateSeuratObject.

activities

tibble | Result of running decoupleR method with progeny regulon prior knowledge.

group.by

character | Metadata variable to group the output by. Has to be a character of factor column.

split.by

character | Secondary metadata variable to further group (split) the output by. Has to be a character of factor column.

slot

character | Data slot to use. Only one of: counts, data, scale.data. Defaults to "data".

statistic

character | DecoupleR statistic to use. One of:

• wmean: For weighted mean.

• norm_wmean: For normalized weighted mean.

• corr_wmean: For corrected weighted mean.

pt.size

numeric | Size of the dots.

border.size

numeric | Width of the border of the cells.

na.value

character | Color value for NA.

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.

legend.length, legend.width

numeric | Length and width of the legend. Will adjust automatically depending on legend side.

legend.framewidth, legend.tickwidth

numeric | Width of the lines of the box in the legend.

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.

legend.type

character | Type of legend to display. One of:

• normal: Default legend displayed by ggplot2.

• colorbar: Redefined colorbar legend, using guide_colorbar.

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.

axis.text.x.angle

numeric | Degree to rotate the X labels. One of: 0, 45, 90.

enforce_symmetry

logical | Return a symmetrical plot axes-wise or continuous color scale-wise, when applicable.

min.cutoff, max.cutoff

numeric | Set the min/max ends of the color scale. Any cell/group with a value lower than min.cutoff will turn into min.cutoff and any cell with a value higher than max.cutoff will turn into max.cutoff. In FeaturePlots, provide as many values as features. Use NAs to skip a feature.

number.breaks

numeric | Controls the number of breaks in continuous color scales of ggplot2-based plots.

diverging.palette

character | Type of symmetrical color palette to use. Out of the diverging palettes defined in brewer.pal.

diverging.direction

numeric | Either 1 or -1. Direction of the divering palette. This basically flips the two ends.

use_viridis

logical | Whether to use viridis color scales.

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.

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.

flip

logical | Whether to invert the axis of the displayed plot.

return_object

logical | Returns the Seurat object with the modifications performed in the function. Nomally, this contains a new assay with the data that can then be used for any other visualization desired.

grid.color

character | Color of the grid in the plot. In heatmaps, color of the border of the cells.

border.color

character | Color for the border of the heatmap body.

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.
