Description

Inspects each column and returns a best-guess R type string. Character columns are tested for common date patterns. Numeric columns containing only 0/1 values (with both present) are flagged as logical.

Usage

detect_types(df)

Arguments

df	A data frame.

Value

A named character vector with one element per column. Possible values: "numeric", "integer", "character", "logical", "factor", "Date", "POSIXct", "unknown".

Examples

df <- data.frame(
  price = c(100.5, 200.3, 300.1),
  rooms = c(2L, 3L, 4L),
  pool  = c("Y", "N", "Y"),
  sold  = c(TRUE, FALSE, TRUE)
)
detect_types(df)
