In Russel88/MicEco: Various functions for microbial community data

Make Euler diagram of shared taxa (ASVs, OTUs) across sample groups

Description

Make Euler diagram of shared taxa (ASVs, OTUs) across sample groups from a phyloseq object. Overlap can be weighted by relative abundance

Usage

ps_euler(
  ps,
  group,
  fraction = 0,
  shape = "circle",
  weight = FALSE,
  relative = TRUE,
  plot = TRUE,
  ...
)

Arguments

ps	A phyloseq object
group	The grouping factor. Should match variable in sample_data(ps)
fraction	The fraction (0 to 1) of samples in a group in which the taxa should be present to be included in the count.
shape	Shape of the plot "circle" or "ellipse"?
weight	If TRUE, the overlaps are weighted by abundance
relative	Should abundances be made relative
plot	If TRUE return a plot, if FALSE return a list with shared and unique taxa
...	Additional arguments

Details

Any further arguments to this function are passed to the plot.euler function from the eulerr package. This can be used to change colors, fonts, and other graphical parameters. For example: ps_euler(phy, "Time", quantities = list(type=c("percent","counts"), font = 2), labels = list(cex = 2), col = "red", fill = c("red","blue","green"))

Value

An euler plot
