ggplot2-methods: Create a new ggplot from a tidySingleCellExperiment object

In tidySingleCellExperiment: Brings SingleCellExperiment to the Tidyverse

Description

'ggplot()' initializes a ggplot object. It can be used to declare the input data frame for a graphic and to specify the set of plot aesthetics intended to be common throughout all subsequent layers unless specifically overridden.

Arguments

.data	Default dataset to use for plot. If not already a data.frame, will be converted to one by [fortify()]. If not specified, must be supplied in each layer added to the plot.
mapping	Default list of aesthetic mappings to use for plot. If not specified, must be supplied in each layer added to the plot.
...	Other arguments passed on to methods. Not currently used.
environment	DEPRECATED. Used prior to tidy evaluation.

Details

'ggplot()' is used to construct the initial plot object, and is almost always followed by '+' to add component to the plot. There are three common ways to invoke 'ggplot()':

The first method is recommended if all layers use the same data and the same set of aesthetics, although this method can also be used to add a layer using data from another data frame. See the first example below. The second method specifies the default data frame to use for the plot, but no aesthetics are defined up front. This is useful when one data frame is used predominantly as layers are added, but the aesthetics may vary from one layer to another. The third method initializes a skeleton 'ggplot' object which is fleshed out as layers are added. This method is useful when multiple data frames are used to produce different layers, as is often the case in complex graphics.

Value

A ggplot

Examples

library(ggplot2)

tidySingleCellExperiment::pbmc_small %>%
    tidy() %>%
    tidySingleCellExperiment::ggplot(aes(groups, nCount_RNA)) +
    geom_boxplot()
