Overview
29 October 2024
Abstract
A brief overview of the tidySpatialExperiment package - demonstrating the SpatialExperiment-tibble abstraction, compatibility with the tidyverse ecosystem, compatibility with the tidyomics ecosystem and a few helpful utility functions.
Package
tidySpatialExperiment 1.2.0
Contents
1 Introduction
tidySpatialExperiment provides a bridge between the
SpatialExperiment
package and the tidyverse ecosystem. It
creates an invisible layer that allows you to interact with a
SpatialExperiment object as if it were a tibble; enabling the use of
functions from dplyr,
tidyr,
ggplot2 and
plotly. But, underneath, your data
remains a SpatialExperiment object.
tidySpatialExperiment also provides five additional utility functions.
1.1 Resources
If you would like to learn more about tidySpatialExperiment and tidyomics, the following links are a good place to start:
The tidyomics ecosystem also includes packages for:
Working with genomic features:
- plyranges, for tidy manipulation of genomic range data.
- nullranges, for tidy generation of genomic ranges representing the null hypothesis.
- plyinteractions, for tidy manipulation of genomic interaction data.
Working with transcriptomic features:
- tidySummarizedExperiment,
for tidy manipulation of
SummarizedExperimentobjects. - tidySingleCellExperiment,
for tidy manipulation of
SingleCellExperimentobjects. - tidyseurat, for
tidy manipulation of
Seuratobjects. - tidybulk, for bulk RNA-seq analysis.
- tidySummarizedExperiment,
for tidy manipulation of
Working with cytometry features:
- tidytof, for tidy manipulation of high-dimensional cytometry data.
And a few associated packages:
- tidygate, for manual gating of points in space.
- tidyheatmap, for modular heatmap contruction.

Here, we attach tidySpatialExperiment and an example SpatialExperiment
object.
# Load example SpatialExperiment object
library(tidySpatialExperiment)
example(read10xVisium)1.5 SpatialExperiment-tibble abstraction
A SpatialExperiment object represents assay-feature values as rows and
cells as columns. Additional information about the cells is stored in the
reducedDims, colData and spatialCoords slots.
tidySpatialExperiment provides a SpatialExperiment-tibble abstraction,
representing cells as rows and cell data as columns, in accordance with the
tidy observation-variable convention. The cell data is made up of information stored in the colData and spatialCoords slots.
The default view is now of the SpatialExperiment-tibble abstraction.

2.1 Manipulate with dplyr
Most functions from dplyr are available for use with the
SpatialExperiment-tibble abstraction. For example, filter() can be used
to filter cells by a variable of interest.
spe |>
filter(array_col < 5)## # A SpatialExperiment-tibble abstraction: 3 × 7
## # Features = 50 | Cells = 3 | Assays = counts
## .cell in_tissue array_row array_col sample_id pxl_col_in_fullres

## # ℹ 1 more variable: pxl_row_in_fullres <int>And mutate can be used to add new variables, or modify the value of an
existing variable.

## # ℹ 40 more rows
## # ℹ 1 more variable: pxl_row_in_fullres <int>2.2 Tidy with tidyr
Most functions from tidyr are also available. Here, nest() is used to
group the data by sample_id, and unnest() is used to ungroup the data.
# Nest the SpatialExperiment object by sample_id
spe_nested <-
spe |>
nest(data = -sample_id)

## # ℹ 40 more rows
## # ℹ 1 more variable: pxl_row_in_fullres <int>2.3 Plot with ggplot2
The ggplot() function can be used to create a plot directly from a
SpatialExperiment object. This example also demonstrates how tidy
operations can be combined to build up more complex analysis.
spe |>
filter(sample_id == "section1" & in_tissue) |>
# Add a column with the sum of feature counts per cell
mutate(count_sum = purrr::map_int(.cell, ~
spe[, .x] |>
counts() |>
sum()
)) |>
# Plot with tidySpatialExperiment and ggplot2
ggplot(aes(x = reorder(.cell, count_sum), y = count_sum)) +
geom_point() +
coord_flip()
2.4 Plot with plotly
The plot_ly() function can also be used to create a plot from a
SpatialExperiment object.
spe |>
filter(sample_id == "section1") |>
plot_ly(
x = ~ array_col,
y = ~ array_row,
color = ~ in_tissue,
type = "scatter"
)
3 Utilities
3.1 Append feature data to cell data
The tidyomics ecosystem places an emphasis on interacting with cell
data. To interact with feature data, the join_features() function can be
used to append assay-feature values to cell data.
# Join feature data in wide format, preserving the SpatialExperiment object
spe |>
join_features(features = c("ENSMUSG00000025915", "ENSMUSG00000042501"), shape = "wide") |>

Sometimes, it is necessary to aggregate the gene-transcript abundance from a group of cells into a single value. For example, when comparing groups of cells across different samples with fixed-effect models.
The aggregate_cells() function can be used to aggregate cells by a
specified variable and assay, returning a SummarizedExperiment object.
spe |>
aggregate_cells(in_tissue, assays = "counts")## class: SummarizedExperiment
## dim: 50 2
## metadata(0):
## assays(1): counts
## rownames(50): ENSMUSG00000002459 ENSMUSG00000005886 ...
## ENSMUSG00000104217 ENSMUSG00000104328
## rowData names(1): feature
## colnames(2): FALSE TRUE
## colData names(3): in_tissue .aggregated_cells sample_id3.3 Elliptical and rectangular region selection
The ellipse() and rectangle() functions can be used to select cells by
their position in space.
spe |>
filter(sample_id == "section1") |>
mutate(in_ellipse = ellipse(array_col, array_row, c(20, 40), c(20, 20))) |>
ggplot(aes(x = array_col, y = array_row, colour = in_ellipse)) +
geom_point()
3.4 Interactive gating
For the interactive selection of cells in space, tidySpatialExperiment experiment provides gate(). This function uses tidygate, shiny and plotly to launch an interactive plot overlaying cells in position with image data. Additional parameters can be used to specify point colour, shape, size and alpha, either with a column in the SpatialExperiment object or a constant value.
spe_gated <-
spe |>
gate(colour = "in_tissue", alpha = 0.8)
A record of which points appear in which gates is appended to the SpatialExperiment object in the .gated column. To select cells which appear within any gates, filter for non-NA values. To select cells which appear within a specific gate, string pattern matching can be used.
# Select cells within any gate
