Description

This is a convenience function that allows you to add an answer option to a question object.

Usage

add_answer_option_to_question(question, ...)

Arguments

Value

The question object.

Examples

myQuestion <-
  limonaid::Question$new(
    code = 'myQuestion',
    type='radio'
  ) |>
  add_answer_option_to_question(
    code = 1,
    optionTexts = "First option"
  ) |>
  add_answer_option_to_question(
    code = 2,
    optionTexts = "Second option"
  );

Description

This is used when creating dataframes for TSV exports.

Usage

append_lsdf_rows(data, row)

Arguments

Value

A merged dataframe.

Examples

limonaid::append_lsdf_rows(mtcars, iris);

Description

The cat0 function is to cat what paste0 is to paste; it simply makes concatenating many strings without a separator easier.

Usage

cat0(..., sep = "")

Arguments

Value

Nothing (invisible NULL, like cat).

Examples

cat0("The first variable is '", names(mtcars)[1], "'.");

Description

Usage

convertToNumeric(vector, byFactorLabel = FALSE)

Arguments

Value

The converted vector.

Examples

convertToNumeric(as.character(1:8));

Description

This function is used by append_lsdf_rows(), and you normally should not use it directly.

Usage

emptyDf(colnames, nrow, fillWith = "")

Arguments

Value

The data.frame.

Examples

limonaid::emptyDf(c("x", "y"), 3);

Description

Sometimes it is useful to export a version of a survey with a different primary language, and/or less additional languages. This function allows that.

Usage

export_with_languages(
  x,
  language,
  path,
  additional_languages = NULL,
  new_sid = x$sid,
  backupLanguage = x$language,
  prefix = "limesurvey--",
  suffix = "",
  parallel = TRUE
)

Arguments

Value

Invisibly, the cloned and altered survey object.

Examples

### Add later

  username = getOption("lime_username"),
  password = getOption("lime_password")
)

Arguments

Value

API token

Usage

ls_apply_script_bits(
  data,
  scriptBits,
  setVarNames = TRUE,

  massConvertToNumeric = TRUE,
  silent = limonaid::opts$get("silent"),
  sticky = limonaid::opts$get("sticky")
)

Arguments

Value

The dataframe.

Description

These are a set of really basic functions that facilitate building LimeSurvey Expression Manager (LSEM) equations.

Usage

ls_eq_build(lhs, operator, rhs)

ls_eq_is(varCode, value, naok = TRUE)

ls_eq_isChecked(varCode, naok = TRUE)

ls_eq_isUnchecked(varCode, naok = TRUE)

ls_eq_if(cond, ifExpr, elseExpr)

ls_eq_ifRegex(regex, varCode, ifExpr, elseExpr, naok = TRUE)

ls_eq_brace(expr)

ls_eq_quote(expr)

Arguments

Details

ls_eq_build() just pastes together its three arguments in the same order using a space as separator. So it's mostly used for clarity when building LSEM equations.

ls_eq_is() uses ls_eq_build() to specify a logical expression that is true when varCode equals value.

ls_eq_if() builds an if/then/else expression; if cond evaluates to TRUE, the LSEM uses ifExpr; otherwise, it uses elseExpr.

ls_eq_ifRegex checks a question against a regular expression.

ls_eq_isChecked() and ls_eq_isUnchecked() return an expression evaluating whether a checkbox is checked (or not).

ls_eq_brace() simply embraces expr, an expression (i.e. it prepends ⁠{⁠ and appends ⁠}⁠).

ls_eq_quote() simply embraces expr, an expression (i.e. it prepends ⁠'⁠ and appends ⁠'⁠).

Value

A character vector.

Examples

ls_eq_build("questionCode", "==", "Y");

Description

This function takes a series of conditions and corresponding values, and builds an equation consisting of nested if statements.

Usage

ls_eq_nestIfs(conditions, values, elseExpr, quoteValues = FALSE)

Arguments

Value

A character value.

Examples

### Relatively simple example with four levels of nesting
ls_eq_nestIfs(c("age.NAOK > 80",
                "age.NAOK > 65",
                "age.NAOK > 40",
                "age.NAOK > 20"),
              c("Respectable",
                "Roughly retired",
                "Roughly middle-aged",
                "Quite young"),
              "Very young",
              quoteValue=TRUE);

Description

This function can be used to import files exported by LimeSurvey.

  scriptfile = NULL,
  setVarNames = TRUE,
  setLabels = TRUE,
  convertToCharacter = FALSE,
  convertToFactor = FALSE,

  massConvertToNumeric = TRUE,
  dataHasVarNames = TRUE,
  dataEncoding = "UTF-8-BOM",
  scriptEncoding = NULL,
  silent = limonaid::opts$get("silent")
)

Arguments

Details

This function was intended to make importing data from LimeSurvey a bit easier. The default settings used by LimeSurvey are not always convenient, and this function provides a bit more control.

Value

The dataframe.

Examples

## Not run: 
### Of course, you need valid LimeSurvey files. This is an example of
### what you'd do if you have them, assuming you specified that path
### containing the data in 'dataPath', the name of the datafile in
### 'dataFileName', the name of the script file in 'dataLoadScriptName',
### and that you only want variables 'informedConsent', 'gender', 'hasJob',
### 'currentEducation', 'prevEducation', and 'country' to be converted to
### factors.
dat <- limonaid::ls_import_data(
  datafile = file.path(dataPath, dataFileName),
  scriptfile = file.path(dataPath, dataLoadScriptName),
  categoricalQuestions = c('informedConsent',
                           'gender',
                           'hasJob',
                           'currentEducation',
                           'prevEducation',
                           'country')
);

## End(Not run)

Description

This function extracts specific code bits from the LimeSurvey data import R script, which can then be applied to imported data using ls_apply_script_bits(), for example to update variable names, set labels, etc.

Usage

ls_parse_data_import_script(
  scriptfile = NULL,
  scriptEncoding = limonaid::opts$get("encoding"),
  silent = limonaid::opts$get("silent")
)

Arguments

Value

A list with four components.

Description

This function is meant to quickly parse the variable labels set by LimeSurvey. It works particularly well with dual anchor array questions, where the left and right anchors as well as the subquestions are extracted automatically.

Usage

ls_process_labels(
  data,
  varnameRegExPairs = NULL,
  lengthToWrap = 50,
  lengthToWrapAnchors = 20,
  labelExtractionRegExPair = limonaid::opts$get("labelExtractionRegExPair"),
  leftAnchorRegExPairs = limonaid::opts$get("leftAnchorRegExPairs"),
  rightAnchorRegExPairs = limonaid::opts$get("rightAnchorRegExPairs")
)

Arguments

Details

This function processes LimeSurvey variable labels and applies regular expressions to automatically extract subquestions and left and right anchors.

Value

A dataframe.

Examples

### No examples provided yet; this would require data to be included,
### and that's not available yet.

Description

Read a LimeSurvey Tab-Separated Values file

Usage

ls_read_tsv(file, encoding = limonaid::opts$get("encoding"))

Arguments

Value

A dataframe.

Examples

### Get location of one of the example files
exampleFile <-
  system.file(
    "extdata",
    "export-of-survey-with-one-question-as-tsv.txt",
    package = "limonaid"
  );

### Import file
lsrv <- limonaid::ls_read_tsv(exampleFile);

Description

This function takes a dataframe with LimeSurvey (LS) variable codes and values, and builds a nested set of LimeSurvey Equation Manager (LSEM) if/then/else equations where the variable code in each row (in the varCodeCol) is compared to the corresponding value (i.e. the value in the same row in the valueCol column) using the operator specified in that row in the operatorCol column (or the == operator, if no operator is specified). In the case of a match, the value in the corresponding recodeToCol column is returned. If there is no match, the comparison on the next row is evaluated, all the way down. If nothing matches, the elseExpr is returned.

Usage

ls_recodeTable_to_equations(
  data,
  varCodeCol = limonaid::opts$get("recTab2Eq_varCodeCol"),
  valueCol = limonaid::opts$get("recTab2Eq_valueCol"),
  recodeToCol = limonaid::opts$get("recTab2Eq_recodeToCol"),
  operatorCol = limonaid::opts$get("recTab2Eq_operatorCol"),
  elseExpr = limonaid::opts$get("eq_elseExpr"),
  naok = TRUE
)

Arguments

Value

A character value.
