Coerce to lfq_data

Generic function to convert various data formats into lfq_data objects. Methods can be defined for specific input classes to enable seamless interoperability with other genomic surveillance packages.

Usage

as_lfq_data(x, ...)

# S3 method for class 'lfq_data'
as_lfq_data(x, ...)

# S3 method for class 'data.frame'
as_lfq_data(x, ...)

Arguments

x

An object to coerce.

...

Additional arguments passed to methods. For the data.frame method, these are passed to lfq_data().

Value

An lfq_data object.

An lfq_data object.

An lfq_data object.

Examples

df <- data.frame(
  date    = rep(as.Date("2024-01-01") + c(0, 7), each = 2),
  lineage = rep(c("A", "B"), 2),
  count   = c(80, 20, 60, 40)
)
x <- as_lfq_data(df, lineage = lineage, date = date, count = count)
