In SRS: Scaling with Ranked Subsampling

Shiny app for scaling with ranked subsampling (SRS)

Description

Shiny app for the determination of Cmin for scaling with ranked subsampling (SRS).

Usage

SRS.shiny.app(data)

Arguments

data	Data frame (species count or OTU table) in which columns are samples and rows are the counts of species or OTUs. Only integers are accepted as data.

Details

Shiny app that generates a visualization of retained samples, summary statistics, SRS curves, and an interactive table in response to varying minimum sample size (Cmin).

Value

Launches Shiny app for SRS in the default web browser.

Examples

##Samples should be arranged columnwise.
##Input data should not contain any categorial
##data such as taxonomic assignment or barcode sequences.
##An example of the input data can be found below:

example_input_data <- matrix(c(sample(1:20, 100, replace = TRUE),
sample(1:30, 100, replace = TRUE),sample(1:40, 100, replace = TRUE)), nrow = 100)
colnames(example_input_data) <- c("sample_1","sample_2","sample_3")
example_input_data <- as.data.frame(example_input_data)
example_input_data

##Launching the SRS shiny app with example_input_data as input
if (interactive()) {SRS.shiny.app(example_input_data)}
