# Generate a data dictionnary and search for variables with `look_for()`

#### Joseph Larmarange

## Showing a summary of a data frame

### Default printing of tibbles

It is a common need to easily get a description of all variables in a data frame.

When a data frame is converted into a tibble (e.g. with `dplyr::as_tibble()`), it as a nice printing showing the first rows of the data frame as well as the type of column.

    library(dplyr)

    iris %>% as_tibble()

    ## # A tibble: 150 × 5

However, when you have too many variables, all of them cannot be printed and their are just listed.

### `dplyr::glimpse()`

The function `dplyr::glimpse()` allows you to have a quick look at all the variables in a data frame.

It will show you the first values of each variable as well as the type of each variable. However, some important informations are not displayed:

- variable labels, when defined;
- value labels for labelled vectors;
- the list of levels for factors;
- the range of values for numerical variables.

### `labelled::look_for()`

`look_for()` provided by the `labelled` package will print in the console a data dictionary of all variables, showing variable labels when available, the type of variable and a list of values corresponding to:

- levels for factors;
- value labels for labelled vectors;
- the range of observed values in the vector otherwise (if `details = "full"`).

Note that `lookfor()` and `generate_dictionary()` are synonyms of `look_for()` and works exactly in the same way.

If there is not enough space to print full labels in the console, they will be truncated (truncation is indicated by a `~`).

## Searching variables by key

When a data frame has dozens or even hundreds of variables, it could become difficult to find a specific variable. In such case, you can provide an optional list of keywords, which can be simple character strings or regular expression, to search for specific variables.

    # Look for a single keyword.
    look_for(iris, "petal")

    ##  pos variable     label           col_type missing values
    ##  3   Petal.Length Length of petal dbl      0
    ##  4   Petal.Width  Width of Petal  dbl      0

    look_for(iris, "s")

    ##  pos variable     label col_type missing values
    ##  1   Sepal.Length —     dbl      0
    ##  2   Sepal.Width  —     dbl      0
    ##  5   Species      —     fct      0       setosa
    ##                                          versicolor
    ##                                          virginica

    # Look for with a regular expression
    look_for(iris, "petal|species")

    ##  pos variable     label           col_type missing values
    ##  3   Petal.Length Length of petal dbl      0
    ##  4   Petal.Width  Width of Petal  dbl      0
    ##  5   Species      —               fct      0       setosa
    ##                                                    versicolor
    ##                                                    virginica

    look_for(iris, "s$")

    ##  pos variable label col_type missing values
    ##  5   Species  —     fct      0       setosa

    # Look for with several keywords
    look_for(iris, "pet", "sp")

    ##  pos variable     label           col_type missing values

    look_for(women, "read", "level")

    ##                                                        [3] higher

By default, `look_for()` will look through both variable names and variables labels. Use `labels = FALSE` to look only through variable names.

    look_for(women, "read")

    ##  pos variable  label           col_type missing values
    ##  13  newspaper Read newspaper? dbl+lbl  0       [0] no
    ##                                                 [1] yes

    look_for(women, "read", labels = FALSE)

    ## Nothing found. Sorry.

Similarly, the search is by default case insensitive. To make the search case sensitive, use `ignore.case = FALSE`.

    look_for(iris, "sepal")

    ##  pos variable     label col_type missing values
    ##  1   Sepal.Length —     dbl      0
    ##  2   Sepal.Width  —     dbl      0

    look_for(iris, "sepal", ignore.case = FALSE)

    ## Nothing found. Sorry.

## Level of details

If you just want to use the search feature of `look_for()` without computing the details of each variable, simply indicate `details = "none"` or `details = FALSE`.

    look_for(women, "id", details = "none")

    ##  pos variable          label
    ##   1  id_woman          Woman Id
    ##   2  id_household      Household Id
    ##   7  residency         Urban / rural residency
    ##  16  ideal_nb_children Ideal number of children

If you want more details (but can be time consuming for big data frames), indicate `details = "full"` or `details = TRUE`.

    look_for(women, details = "full")

    ##  pos variable          label                  col_type missing unique_values
    ##  1   id_woman          Woman Id               dbl      0       2000

## Advanced usages of `look_for()`

`look_for()` returns a detailed tibble which is summarized before printing. To deactivate default printing and see full results, simply use `dplyr::as_tibble()`, `dplyr::glimpse()` or even `utils::View()`.

    look_for(women) %>% View()

    look_for(women) %>% as_tibble()

The tibble returned by `look_for()` could be easily manipulated for advanced programming.

When a column has several values for one variable (e.g. `levels` or `value_labels`), results as stored with nested named list. You can convert named lists into simpler character vectors, you can use `convert_list_columns_to_character()`.

    look_for(women) %>% convert_list_columns_to_character()

Alternatively, you can use `lookfor_to_long_format()` to transform results into a long format with one row per factor level and per value label.

    look_for(women) %>% lookfor_to_long_format()
