dot.plot: Dot plot visualization
Description
Intuitive way of visualizing how gene expression changes across different identity classes (clusters).
The size of the dot encodes the percentage of cells within a class, while the color encodes the
average expression level of 'expressing' cells (green is high).
Usage
dot.plot(object, genes.plot, cex.use = 2, cols.use = NULL, thresh.col = 2.5, dot.min = 0.05, group.by = NULL)
Arguments
genes.plot
Input vector of genes
cex.use
Scaling factor for the dots (scales all dot sizes)
cols.use
Colors to use for plotting
thresh.col
The raw data value which corresponds to a red dot (lowest expression)
dot.min
The fraction of cells at which to draw the smallest dot (default is 0.05)
group.by
Group (color) cells in different ways (for example, orig.ident)
Value
Only graphical output
