Arguments

inSCE

Input SingleCellExperiment object with saved dimension reduction components or a variable with saved results. Required.

slotName

Desired slot of SingleCellExperiment used for plotting. Possible options: "assays", "colData", "metadata", "reducedDims". Required.

itemName

Desired vector within the slot used for plotting. Required.

feature

Desired name of feature stored in assay of SingleCellExperiment object. Only used when "assays" slotName is selected. Default NULL.

sample

Character vector. Indicates which sample each cell belongs to.

dimension

Desired dimension stored in the specified reducedDims. Either an integer which indicates the column or a character vector specifies column name. By default, the 1st dimension/column will be used. Only used when "reducedDims" slotName is selected. Default NULL.

groupBy

Groupings for each numeric value. A user may input a vector equal length to the number of the samples in the SingleCellExperiment object, or can be retrieved from the colData slot. Default NULL.

violin

Boolean. If TRUE, will plot the violin plot. Default TRUE.

boxplot

Boolean. If TRUE, will plot boxplots for each violin plot. Default TRUE.

dots

Boolean. If TRUE, will plot dots for each violin plot. Default TRUE.

plotOrder

Character vector. If set, reorders the violin plots in the order of the character vector when 'groupBy' is set. Default NULL.

xlab

Character vector. Label for x-axis. Default NULL.

ylab

Character vector. Label for y-axis. Default NULL.

axisSize

Size of x/y-axis ticks. Default 10.

axisLabelSize

Size of x/y-axis labels. Default 10.

dotSize

Size of dots. Default 0.1.

transparency

Transparency of the dots, values will be 0-1. Default 1.

defaultTheme

Removes grid in plot and sets axis title size to 10 when TRUE. Default TRUE.

gridLine

Adds a horizontal grid line if TRUE. Will still be drawn even if defaultTheme is TRUE. Default FALSE.

summary

Adds a summary statistic, as well as a crossbar to the violin plot. Options are "mean" or "median". Default NULL.

title

Title of plot. Default NULL.

titleSize

Size of title of plot. Default 15.

hcutoff

Adds a horizontal line with the y-intercept at given value. Default NULL.

hcolor

Character. A color available from 'colors()'. Controls the color of the horizontal cutoff line, if drawn. Default 'black'.

hsize

Size of horizontal line, if drawn. Default 0.5.

hlinetype

Type of horizontal line, if drawn. can be specified with either an integer or a name (0 = blank, 1 = solid, 2 = dashed, 3 = dotted, 4 = dotdash, 5 = longdash, 6 = twodash). Default 1.

vcutoff

Adds a vertical line with the x-intercept at given value. Default NULL.

vcolor

Character. A color available from 'colors()'. Controls the color of the vertical cutoff line, if drawn. Default 'black'.

vsize

Size of vertical line, if drawn. Default 0.5.

vlinetype

Type of vertical line, if drawn. can be specified with either an integer or a name (0 = blank, 1 = solid, 2 = dashed, 3 = dotted, 4 = dotdash, 5 = longdash, 6 = twodash). Default 1.

combinePlot

Must be either "all", "sample", or "none". "all" will combine all plots into a single .ggplot object, while "sample" will output a list of plots separated by sample. Default "none".

plotLabels

labels to each plot. If set to "default", will use the name of the samples as the labels. If set to "none", no label will be plotted.

Value

a ggplot of the violin plot.

Examples

data("mouseBrainSubsetSCE")
plotSCEViolin(
  inSCE = mouseBrainSubsetSCE, slotName = "assays",
  itemName = "counts", feature = "Apoe", groupBy = "sex"
)
