Get the mean and standard deviation of a variable in a clean table

The point of the function is to get the mean/SD in a clean formatted string. It does not add much on top of dplyr functions, but allows to perform the required computations in a single line of code to use them inside other functions (e.g., get_full_model_table()).

Usage

get_mean_sd(df, groups)

Arguments

df

A data frame containing the variable to be summarised in long format, with its name in a column and the associated values in a value column. This is for example the output of get_longer(study_data).

groups

A grouping variable (e.g. Group or Cluster) without quotes.

Value

A data frame summarising the mean and standard deviation of the variable for each group in a wide format with one column per group.

Examples

df_vviq  <- study_data |> get_longer() |> dplyr::filter(Variable == "VVIQ")
vviq_mean_sd <- get_mean_sd(df_vviq, Group)
print(vviq_mean_sd)
#> # A tibble: 1 × 2
#>   Control       Aphantasic  
#>   <chr>         <chr>       
#> 1 58.08 (10.81) 18.33 (4.24)
