read_ods {readODS}

Read Data From (F)ODS File

Description

read_ods is a function to read a single sheet from an (f)ods file and return a data frame. The function can be used for reading both ods and flat ods files. (read_fods) is also available, which can only read flat ods files.

Usage

read_ods(
  path,
  sheet = 1,
  col_names = TRUE,
  col_types = NULL,
  na = "",
  skip = 0,
  formula_as_formula = FALSE,
  range = NULL,
  row_names = FALSE,
  strings_as_factors = FALSE,
  verbose = FALSE,
  as_tibble = TRUE,
  .name_repair = "unique",
  ods_format = c("auto", "ods", "fods"),
  guess = FALSE,
  trim_ws = TRUE,
  n_max = Inf
)

read_fods(
  path,
  sheet = 1,
  col_names = TRUE,
  col_types = NULL,
  na = "",
  skip = 0,
  formula_as_formula = FALSE,
  range = NULL,
  row_names = FALSE,
  strings_as_factors = FALSE,
  verbose = FALSE,
  as_tibble = TRUE,
  .name_repair = "unique",
  trim_ws = TRUE,
  n_max = Inf
)

Arguments

path

path to the (f)ods file.

sheet

sheet to read. Either a string (the sheet name), or an integer sheet number. The default is 1.

col_names

logical, indicating whether the file contains the names of the variables as its first line. Default is TRUE.

col_types

Either NULL to guess from the spreadsheet or refer to readr::type_convert() to specify cols specification. It can also be a shorthand such as "ccf" ("character", "character", "factor"), a list, or an object created by readr::cols(). NA will return a data frame with all columns being "characters". Please note that it will not speed up the reading by a lot by specifying this parameter explicitly. It is more for accuracy.

na

Character vector of strings to use for missing values. By default read_ods converts blank cells to missing data. It can also be set to NULL, so that empty cells are treated as NA.

skip

the number of lines of the data file to skip before beginning to read data. If this parameter is larger than the total number of lines in the ods file, an empty data frame is returned.

formula_as_formula

logical, a switch to display formulas as formulas "SUM(A1:A3)" or as the resulting value "3"... or "8".. . Default is FALSE.

range

selection of rectangle using Excel-like cell range, such as range = "D12:F15" or range = "R1C12:R6C15". Cell range processing is handled by the cellranger package. If sheet name is in the range, such as range = "Sheet2!A2:B7", this sheet name is used instead of the provided sheet. If sheet is not the default value (1), a warning is given.

row_names

logical, indicating whether the file contains the names of the rows as its first column. Default is FALSE.

strings_as_factors

logical, if character columns to be converted to factors. Default is FALSE.

verbose

logical, if messages should be displayed. Default is FALSE.

as_tibble

logical, if the output should be a tibble (as opposed to a data.frame). Default is TRUE.

.name_repair

A string or function passed on as .name_repair to tibble::as_tibble()

• "minimal": No name repair

• "unique" : Make sure names are unique and not empty

• "check_unique": Check names are unique, but do not repair

• "universal" : Checks names are unique and valid R variables names in scope

• A function to apply custom name repair.

Default is "unique".

ods_format

character, must be "auto", "ods" or "fods". The default "auto" is to determine the format automatically. By default, the format is determined by file extension, unless guess is FALSE.

guess

logical, If the file extension is absent or not recognized, this controls whether we attempt to guess format based on the file signature or "magic number".

trim_ws

logical, should leading and trailing whitespace be trimmed?

n_max

numeric, Maximum number of data rows to read. Ignored if range is given.

Value

A tibble (tibble) or data frame (data.frame) containing a representation of data in the (f)ods file.

Examples

## Not run: 
# Read an ODS file
read_ods("starwars.ods")
# Read a specific sheet, e.g. the 2nd sheet
read_ods("starwars.ods", sheet = 2)
# Read a specific range, e.g. A1:C11
read_ods("starwars.ods", sheet = 2, range = "A1:C11")
# Read an FODS file
read_ods("starwars.fods")
# Read a specific sheet, e.g. the 2nd sheet
read_ods("starwars.fods", sheet = 2)
# Read a specific range, e.g. A1:C11
read_ods("starwars.fods", sheet = 2, range = "A1:C11")
# Give a warning and read from Sheet1 (not 2)
read_ods("starwars.fods", sheet = 2, range = "Sheet1!A1:C11")
# Specifying col_types as shorthand, the third column as factor; other by guessing
read_ods("starwars.ods", col_types = "??f")
# Specifying col_types as list
read_ods("starwars.ods", col_types = list(species = "f"))
# Using read_fods, although you don't have to
read_ods("starwars.fods")
