plotDimReduceModule: Plotting Celda module probability on a dimension reduction...
In celda: CEllular Latent Dirichlet Allocation

Description Usage Arguments Value Examples

Create a scatterplot for each row of a normalized gene expression matrix where x and y axis are from a data dimension reduction tool. The cells are colored by the module probability.

`x`	Numeric matrix or a SingleCellExperiment object with the matrix located in the assay slot under `useAssay`. Rows represent features and columns represent cells.
`...`	Ignored. Placeholder to prevent check warning.
`reducedDimName`	The name of the dimension reduction slot in `reducedDimNames(x)` if `x` is a SingleCellExperiment object. Ignored if both `dim1` and `dim2` are set.
`dim1`	Numeric vector. First dimension from data dimension reduction output.
`dim2`	Numeric vector. Second dimension from data dimension reduction output.
`useAssay`	A string specifying which assay slot to use if `x` is a SingleCellExperiment object. Default "counts".
`altExpName`	The name for the altExp slot to use. Default "featureSubset".
`modules`	Character vector. Module(s) from celda model to be plotted. e.g. c("1", "2").
`rescale`	Logical. Whether rows of the matrix should be rescaled to [0, 1]. Default TRUE.
`limits`	Passed to scale_colour_gradient. The range of color scale.
`size`	Numeric. Sets size of point on plot. Default 1.
`xlab`	Character vector. Label for the x-axis. Default "Dimension_1".
`ylab`	Character vector. Label for the y-axis. Default "Dimension_2".
`colorLow`	Character. A color available from 'colors()'. The color will be used to signify the lowest values on the scale.
`colorHigh`	Character. A color available from 'colors()'. The color will be used to signify the highest values on the scale.
`ncol`	Integer. Passed to facet_wrap. Specify the number of columns for facet wrap.
`decreasing`	logical. Specifies the order of plotting the points. If `FALSE`, the points will be plotted in increasing order where the points with largest values will be on top. `TRUE` otherwise. If `NULL`, no sorting is performed. Points will be plotted in their current order in `x`. Default `FALSE`.
`celdaMod`	Celda object of class "celda_G" or "celda_CG". Used only if `x` is a matrix object.
