What is tidygate

It interactively or programmately labels points within custom gates on two dimensions, according to tidyverse principles. The information is added to your tibble. It is based on the package gatepoints from Wajid Jawaid.

The main benefits are

• in interactive mode you can draw your gates on extensive ggplot-like scatter plots
• you can draw multiple gates
• you can save your gates and apply the programmatically.

Input

A tibble of this kind

| dimension1 | dimension2 | annotations | |-----------------|------------|-------------| | chr or fctr | numeric | … |

Step-by-step instructons for Rstudio

1) Execute the following code in the console panel

tidygate_gate <-
  tidygate_data %>%
  mutate( gate = gate_chr( Dim1, Dim2 ) )

2) look at the Viewer and draw a gate clicking at least three times on the plot

3) Click the finish button on the top-right corner, or press escape on your keyboard

Programmatic gating

We can use previously drawn gates to programmately add the gate column

tidygate_data %>%
  mutate( gate = gate_chr(
    Dim1, Dim2,
     # Pre-defined gates
    gate_list = my_gates
  ))

## # A tibble: 2,240 x 9
