Set of functions to supplement the tidyselect set of
functions for selecting columns of data frames (and other items as well).

`all_continuous()`

selects continuous variables

`all_continuous2()`

selects only type `"continuous2"`

`all_categorical()`

selects categorical (including `"dichotomous"`

) variables

`all_dichotomous()`

selects only type `"dichotomous"`

`all_tests()`

selects variables by the name of the test performed

`all_stat_cols()`

selects columns from `tbl_summary`

/`tbl_svysummary`

object with summary statistics (i.e. `"stat_0"`

, `"stat_1"`

, `"stat_2"`

, etc.)

`all_interaction()`

selects interaction terms from a regression model

`all_intercepts()`

selects intercept terms from a regression model

`all_contrasts()`

selects variables in regression model based on their type of contrast

all_continuous(continuous2 = TRUE)
all_continuous2()
all_categorical(dichotomous = TRUE)
all_dichotomous()
all_tests(tests = NULL)
all_stat_cols(stat_0 = TRUE)
all_interaction()
all_intercepts()
all_contrasts(contrasts_type = NULL)

## Arguments

continuous2 |
Logical indicating whether to include continuous2 variables. Default is `TRUE` |

dichotomous |
Logical indicating whether to include dichotomous variables.
Default is `TRUE` |

tests |
string indicating the test type of the variables to select, e.g.
select all variables being compared with `"t.test"` |

stat_0 |
When `FALSE` , will not select the `"stat_0"` column. Default is `TRUE` |

contrasts_type |
type of contrast to select. When `NULL` , all variables with a
contrast will be selected. Default is `NULL` . Select among contrast types
`c("treatment", "sum", "poly", "helmert", "other")` |

## Value

A character vector of column names selected
