inSCE | Input SingleCellExperiment object with saved dimension reduction components or a variable with saved results. Required. |
---|---|
feature | Name of feature stored in assay of SingleCellExperiment object. |
reducedDimName | saved dimension reduction name in the SingleCellExperiment object. Required. |
sample | Character vector. Indicates which sample each cell belongs to. |
featureLocation | Indicates which column name of rowData to query gene. |
featureDisplay | Indicates which column name of rowData to use to display feature for visualization. |
shape | add shapes to each condition. Default NULL. |
useAssay | Indicate which assay to use. The default is "logcounts" |
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. |
dim1 | 1st dimension to be used for plotting. Can either be a string which specifies the name of the dimension to be plotted from reducedDims, or a numeric value which specifies the index of the dimension to be plotted. Default is NULL. |
dim2 | 2nd dimension to be used for plotting. Can either be a string which specifies the name of the dimension to be plotted from reducedDims, or a numeric value which specifies the index of the dimension to be plotted. Default is NULL. |
bin | Numeric vector. If single value, will divide the numeric values into the `bin` groups. If more than one value, will bin numeric values using values as a cut point. |
binLabel | Character vector. Labels for the bins created by the `bin` parameter. Default NULL. |
dotSize | Size of dots. Default 0.5. |
transparency | Transparency of the dots, values will be 0-1. Default 1. |
colorLow | Character. A color available from `colors()`. The color will be used to signify the lowest values on the scale. Default 'white'. |
colorMid | Character. A color available from `colors()`. The color will be used to signify the midpoint on the scale. Default 'gray'. |
colorHigh | Character. A color available from `colors()`. The color will be used to signify the highest values on the scale. Default 'blue'. |
defaultTheme | adds grid to plot when TRUE. Default TRUE. |
title | Title of plot. Default NULL. |
titleSize | Size of title of plot. Default 15. |
legendTitle | title of legend. Default NULL. |
legendSize | size of legend. Default 10. |
legendTitleSize | size of legend title. Default 12. |
groupBy | Facet wrap the scatterplot based on value.
Default |
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. |
a ggplot of the reduced dimension plot of feature data.
