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 <- tasic2016anno anno <- anno[anno$primarytypeid > 0,] data <- tasic2016rpkm datadf <- cbind(samplename = colnames(data), as.data.frame(t(data[c("Pvalb","Sst","Rorb"),]))) ```

Sample-centric plots:

samplebarplot() 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")

sampleheatmapplot() sample_heatmap_plot(data_df, anno, genes = c("Pvalb","Sst","Rorb"), grouping = "primary_type", log_scale = TRUE, font_size = 5)

samplefireplot() sample_fire_plot(data_df, anno, genes = c("Pvalb","Sst","Rorb"), grouping = "primary_type", log_scale = TRUE, top_value = "lowest", font_size = 5)

Group-centric plots:

groupviolinplot() group_violin_plot(data_df, anno, genes = c("Pvalb","Sst","Rorb"), grouping = "primary_type", log_scale = FALSE, font_size = 5, rotate_counts = TRUE)

groupquasirandomplot() group_quasirandom_plot(data_df, anno, genes = c("Pvalb","Sst","Rorb"), grouping = "primary_type", log_scale = FALSE, font_size = 5, rotate_counts = TRUE)

groupdotplot() group_dot_plot(data_df, anno, genes = c("Pvalb","Sst","Rorb"), grouping = "primary_type", log_scale = TRUE, font_size = 5, max_size = 5, rotate_counts = TRUE)

groupboxplot() group_box_plot(data_df, anno, genes = c("Pvalb","Sst","Rorb"), grouping = "primary_type", log_scale = FALSE, font_size = 5, rotate_counts = TRUE)

groupheatmapplot() group_heatmap_plot(data_df, anno, genes = c("Pvalb","Sst","Rorb"), grouping = "primary_type", stat = "tmean", log_scale = TRUE, font_size = 5, rotate_counts = TRUE)
