Restore the type of columns according to a reference data frame

Usage

data_restoretype(data, reference = NULL, ...)

Arguments

data: A data frame for which to restore the column types.
reference: A reference data frame from which to find the correct column types. If NULL, each column is converted to numeric if it doesn't generate NAs. For example, c("1", "2") can be converted to numeric but not c("Sepal.Length").
...: Currently not used.

Value

A data frame with columns whose types have been restored based on the reference data frame.

Examples

data <- data.frame(
  Sepal.Length = c("1", "3", "2"),
  Species = c("setosa", "versicolor", "setosa"),
  New = c("1", "3", "4")
)

fixed <- data_restoretype(data, reference = iris)
summary(fixed)
