安装

## You might need to install the dependencies below if they are not available in your R library.
bioc.packages <- c("biomaRt","GenomeInfoDb","EnsDb.Hsapiens.v86","GEOquery","simplifyEnrichment","ComplexHeatmap")
BiocManager::install(bioc.packages)
dev.packages <- c("chris-mcginnis-ucsf/DoubletFinder","Novartis/hdf5r","mojaveazure/loomR")
devtools::install_github(dev.packages)
## If you can't get the hdf5r package installed, please see the fix here:

使用

###Prepare data for ploting
circ_data <- prepare_circlize_data(iri.integrated, scale = 0.8 )
set.seed(1234)
cluster_colors<-rand_color(length(levels(iri.integrated)))
group_colors<-rand_color(length(names(table(iri.integrated$Group))))
rep_colors<-rand_color(length(names(table(iri.integrated$orig.ident))))

###plot and save figures
# png(filename =  'circlize_plot.png', width = 6, height = 6,units = 'in', res = 300)
plot_circlize(circ_data,do.label = T, pt.size = 0.01, col.use = cluster_colors ,bg.color = 'white', kde2d.n = 200, repel = T, label.cex = 0.6)
add_track(circ_data, group = "Group", colors = group_colors, track_num = 2) ## can change it to one of the columns in the meta data of your seurat object
add_track(circ_data, group = "orig.ident",colors = rep_colors, track_num = 3) ## can change it to one of the columns in the meta data of your seurat object
#dev.off()
