Data Modification and Analysis for Communication Research.

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 tidycomm from CRAN:

install.packages("tidycomm")

Or install the most recent development version of tidycomm with:

remotes::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 × 15
#>   Variable             N Missing     M    SD   Min   Q25   Mdn   Q75   Max Range
#> * <chr>            <int>   <int> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl>
#> 1 autonomy_select…  1197       3  3.88 0.803     1     4     4     4     5     4
#> 2 autonomy_emphas…  1195       5  4.08 0.793     1     4     4     5     5     4
#> # ℹ 4 more variables: CI_95_LL <dbl>, CI_95_UL <dbl>, 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 × 15
#>    Variable           N Missing     M     SD   Min   Q25   Mdn   Q75   Max Range
#>  * <chr>          <int>   <int> <dbl>  <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl>
#>  1 autonomy_sele…  1197       3  3.88  0.803     1  4        4     4     5     4
#>  2 autonomy_emph…  1195       5  4.08  0.793     1  4        4     5     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

#> # ℹ 4 more variables: CI_95_LL <dbl>, CI_95_UL <dbl>, 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 × 8
#>   Variable     n_Units n_Coders n_Categories Level   Agreement Holstis_CR
#> * <chr>          <int>    <int>        <int> <chr>       <dbl>      <dbl>
#> 1 type              45        6            4 nominal     1          1    
#> 2 n_pictures        45        6            7 nominal     0.822      0.930
#> 3 pop_elite         45        6            6 nominal     0.733      0.861
#> 4 pop_people        45        6            2 nominal     0.778      0.916
#> 5 pop_othering      45        6            4 nominal     0.867      0.945
#> # ℹ 1 more variable: Krippendorffs_Alpha <dbl>
