atype {easyr}

Auto-Type

Description

Use easyr date and number and conversion functions to automatically convert data to the most useful type available.

Usage

atype(
  x,
  auto_convert_dates = TRUE,
  allow_times = FALSE,
  check_numbers = TRUE,
  nazero = FALSE,
  check_logical = TRUE,
  isexcel = TRUE,
  stringsAsFactors = FALSE,
  nastrings = easyr::nastrings,
  exclude = NULL
)

Arguments

x

Data to auto-type.

auto_convert_dates

Choose to convert dates.

allow_times

Choose if you want to get times. Only use this if your data has times, otherwise there is a small chance it will prevent proper date conversion.

check_numbers

Choose to convert numbers.

nazero

Convert NAs in numeric columns to 0.

check_logical

Choose to convert numbers.

isexcel

By default, we assume this data may have come from excel. This is to assist in date conversion from excel integers. If you know it didn't and are having issues with data conversion, set this to FALSE.

stringsAsFactors

Convert strings/characters to factors to save compute time, RAM/memory, and storage space.

nastrings

Strings to consider NA.

exclude

Column name(s) to exclude.

Examples

# create some data in all-characters.
x = data.frame(
     char = c( 'abc', 'def' ),
     num = c( '1', '2' ),
     date = c( '1/1/2018', '2018-2-01' ),
     na = c( NA, NA ),
     bool = c( 'TRUE', 'FALSE' ),
     stringsAsFactors = FALSE
)

# different atype options. Note how the output types change.
str( atype( x ) )
str( atype( x, exclude = 'date' ) )
str( atype( x, auto_convert_dates = FALSE ) )
str( atype( x, check_logical = FALSE ) )
