scrattch.vis
Single-cell RNA-seq visualization tools.
This package is under heavy development and optimization.
Installation
All of the dependencies for scrattch.vis are available from CRAN. You can install scrattch.vis from Github using:
install.packages("devtools")
devtools::install_github("AllenInstitute/scrattch.vis")
Plot Types
Once installed, scrattch.vis provides a variety of functions for visualizing scRNA-seq data based on sample annotations. Each of these returns a ggplot2 plot object:
Load packages and data:
library(tasic2016data)
library(scrattch.vis)
options(stringsAsFactors = F)
anno <- tasic_2016_anno
anno <- anno[anno$primary_type_id > 0,]
data <- tasic_2016_rpkm
data_df <- cbind(sample_name = colnames(data),
as.data.frame(t(data[c("Pvalb","Sst","Rorb"),])))
Sample-centric plots:
sample_bar_plot()
sample_bar_plot(data_df,
anno,
genes = c("Pvalb","Sst","Rorb"),
grouping = "primary_type",
group_order = c(1,6,2,9,4),
log_scale = FALSE,
font_size = 5,
label_type = "angle")
sample_heatmap_plot()
sample_heatmap_plot(data_df,
anno,
genes = c("Pvalb","Sst","Rorb"),
grouping = "primary_type",
log_scale = TRUE,
font_size = 5)
sample_fire_plot()
sample_fire_plot(data_df,
anno,
