Load a delimited file (CSV/TSV) into a [`VennDataset-class`]

Source: R/io.R
load_csv.Rd

Supports two layouts: * Binary mode (default): one row per item, with 0/1 columns marking membership in each set. The first `prefix_cols` columns are item metadata; remaining columns are sets. * Aggregated mode (`binary = FALSE`): each column is a set, and cells contain item identifiers. Empty cells are ignored.

Usage

load_csv(path, binary = TRUE, delimiter = NULL, prefix_cols = 1L)

Arguments

path

Path to the file.

binary

`TRUE` for binary 0/1 mode (default), `FALSE` for aggregated.

delimiter

Explicit delimiter override. `NULL` auto-detects from `,`, `;`, tab, and space.

prefix_cols

Number of leading metadata columns in binary mode (default 1). Ignored when `binary = FALSE`.

Value

A [`VennDataset-class`].

Examples

tmp <- tempfile(fileext = ".csv")
writeLines(c("Gene,SetA,SetB", "G1,1,0", "G2,1,1", "G3,0,1"), tmp)
ds <- load_csv(tmp, binary = TRUE)
ds@set_names
#> [1] "SetA" "SetB"
