tidycomm

Tidycomm provides convenience functions for common tasks in communication research. All functions follow the style and syntax of the tidyverse.

Currently, tidycomm includes functions for various methods of univariate and bivariate data description and analysis, data modification, and intercoder reliability tests.

Installation

Install the most recent development version of tidycomm with:

devtools::install_github("joon-e/tidycomm")

Usage

library(tidycomm)

tidycomm functions follow the style and syntax of the tidyverse functions:

• they always assume a tibble as their first argument
• they will always return a tibble as well, so they can be easily integrated into pipes
• data variables (tibble columns) are passed to function calls directly as symbols

WoJ %>% # Worlds of Journalism sample data
  describe(autonomy_selection, autonomy_emphasis)
#> # A tibble: 2 x 13
#>   Variable     N Missing     M    SD   Min   Q25   Mdn   Q75   Max Range
#>   <chr>    <int>   <int> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl>
#> 1 autonom~  1200       3  3.88 0.803     1     4     4     4     5     4
#> 2 autonom~  1200       5  4.08 0.793     1     4     4     5     5     4
#> # ... with 2 more variables: Skewness <dbl>, Kurtosis <dbl>

Most functions will automatically use all relevant variables in the data if no variables are specified in the function call. For example, to compute descriptive statistics for all numeric variables in the data, just call describe() without further arguments:

WoJ %>% 
  describe()
#> # A tibble: 11 x 13
#>    Variable     N Missing     M     SD   Min   Q25   Mdn   Q75   Max Range
#>    <chr>    <int>   <int> <dbl>  <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl>
#>  1 autonom~  1200       3  3.88  0.803     1  4        4     4     5     4
#>  2 autonom~  1200       5  4.08  0.793     1  4        4     5     5     4
#>  3 ethics_1  1200       0  1.63  0.892     1  1        1     2     5     4
#>  4 ethics_2  1200       0  3.21  1.26      1  2        4     4     5     4
#>  5 ethics_3  1200       0  2.39  1.13      1  2        2     3     5     4
#>  6 ethics_4  1200       0  2.58  1.25      1  1.75     2     4     5     4
#>  7 work_ex~  1200      13 17.8  10.9       1  8       17    25    53    52
#>  8 trust_p~  1200       0  3.05  0.811     1  3        3     4     5     4
#>  9 trust_g~  1200       0  2.82  0.854     1  2        3     3     5     4
#> 10 trust_p~  1200       0  2.42  0.736     1  2        2     3     4     3
#> 11 trust_p~  1200       0  2.52  0.712     1  2        3     3     4     3
#> # ... with 2 more variables: Skewness <dbl>, Kurtosis <dbl>

Likewise, compute intercoder reliability tests for all variables by only specifying the post and coder ID variables:

fbposts %>% # Facebook post codings sample data
  test_icr(post_id, coder_id)
#> # A tibble: 5 x 8
#>   Variable n_Units n_Coders n_Categories Level Agreement Holstis_CR
#>   <chr>      <int>    <int>        <int> <chr>     <dbl>      <dbl>
#> 1 type          45        6            4 nomi~     1          1    
#> 2 n_pictu~      45        6            7 nomi~     0.822      0.930
#> 3 pop_eli~      45        6            6 nomi~     0.733      0.861
#> 4 pop_peo~      45        6            2 nomi~     0.778      0.916
#> 5 pop_oth~      45        6            4 nomi~     0.867      0.945
#> # ... with 1 more variable: Krippendorffs_Alpha <dbl>
