i have the following data frame in R with 3 factor column with the same levels like this :
| A | B | C |
|---|---|---|
| 1 1-Strongly disagree | 5-Strongly agree | 1-Strongly disagree |
| 2 3-so-so | 5-Strongly agree | 2-Disagree |
| 3 4-Agree | 2-Disagree | 2-Disagree |
| 4 2-Disagree | 2-Disagree | 5-Strongly agree |
and i want to use dplyr functions in order to alter my data frame into like this :
| Item | 1-Strongly disagree | 2-Disagree | 3-so-so | 4-Agree | 5-Strongly agree |
|---|---|---|---|---|---|
| A | 26.72 | 21.41 | 27.45 | 17.80 | 6.59 |
| B | 25.0 | 20.2 | 28.27 | 18.36 | 8.0 |
| C | 6.3 | 9.5 | 28.6 | 40.35 | 15.17 |
where the numbers on the cells are arbitrary.
A = sample(c('1-Strongly disagree','2-Disagree','3-so-so','4-Agree','5-Strongly agree'),1000,replace = TRUE)
B = sample(c('1-Strongly disagree','2-Disagree','3-so-so','4-Agree','5-Strongly agree'),1000,replace = TRUE)
C = sample(c('1-Strongly disagree','2-Disagree','3-so-so','4-Agree','5-Strongly agree'),1000,replace = TRUE)
df = tibble(A,B,C)%>%
mutate(across(everything(),as.factor));df
library(tidyverse)
set.seed(1234) # for reproducible testing
A = sample(c('1-Strongly disagree','2-Disagree','3-so-so','4-Agree','5-Strongly agree'),1000,replace = TRUE)
B = sample(c('1-Strongly disagree','2-Disagree','3-so-so','4-Agree','5-Strongly agree'),1000,replace = TRUE)
C = sample(c('1-Strongly disagree','2-Disagree','3-so-so','4-Agree','5-Strongly agree'),1000,replace = TRUE)
df = tibble(A,B,C)%>%
mutate(across(everything(),as.factor));df
df |>
pivot_longer(cols = everything(), names_to = "Item") |>
pivot_wider(names_from = value, values_fn = length)
gives
# A tibble: 3 × 6
Item `4-Agree` `1-Strongly disagree` `2-Disagree` `5-Strongly agree` `3-so-so`
