I'm having trouble getting my data set to work with the table() function. My data originally looks something like this:
| Student_Ethnicity | Pre_DAS Ethnicity |
|---|---|
| White | Black |
| White | White |
| Asian | Black |
| Black | White |
| White | Black |
But, I want it to tabulate like this:
| Student_Ethnicity | White | Black | Asian |
|---|---|---|---|
| White | 1 | 2 | 0 |
| Black | 1 | 0 | 0 |
| Asian | 0 | 1 | 0 |
I previously ran this code:
PreDASEthnicityPredictor <- table(Predict_DAS$Student_Ethnicity, Predict_DAS$PreDAS_Ethnicity)
But, when the data tabulated it looked like this:
| Student_Ethnicity | Pre_DAS Ethnicity | Frq |
|---|---|---|
| White | White | 1 |
| White | Black | 2 |
| White | Asian | 0 |
| Black | White | 1 |
| Black | Black | 0 |
| Black | Asian | 0 |
| Asian | White | 0 |
| Asian | Black | 1 |
| Asian | Asian | 0 |
Is there a specific reason this could be happening and how can I make this tabulate correctly? It is important to get this table format for a chi-squared analysis I would like to do on this later.
Here is the actual dataset I am working with:
structure(list(Predict_DAS.Student_Ethnicity = c("White/Caucasian",

Assuming your data set is called df, you could do the following with the tidyverse packages:
library(tidyverse)
result <- df %>%
count(Predict_DAS.Student_Ethnicity, Predict_DAS.PreDAS_Ethnicity) %>%
pivot_wider(names_from = Predict_DAS.PreDAS_Ethnicity, values_from = n, values_fill = 0)
Predict_DAS.Student_Ethnicity `Black/African…` `No Selection` `White/Caucasi…` Asian Other

3 Black/African American 19 11 2 1 0

I suspect the problem is that the 'levels' of your factor (PreDAS_Ethnicity) don't match your expected outcome. Here is a potential solution specifying the levels before 'table()ing' the data:
Predict_DAS <- read.table(text = "Student_Ethnicity PreDAS_Ethnicity
White Black
White White
Asian Black
Black White
White Black", header = TRUE)
Predict_DAS$Student_Ethnicity <- factor(Predict_DAS$Student_Ethnicity, levels = unique(Predict_DAS$Student_Ethnicity))
Predict_DAS$PreDAS_Ethnicity <- factor(Predict_DAS$PreDAS_Ethnicity, levels = unique(Predict_DAS$Student_Ethnicity))
PreDASEthnicityPredictor <- table(Predict_DAS$Student_Ethnicity, Predict_DAS$PreDAS_Ethnicity)
PreDASEthnicityPredictor
#>
#> White Asian Black
#> White 1 0 2
#> Asian 0 0 1
#> Black 1 0 0

df <- structure(list(Predict_DAS.Student_Ethnicity = c("White/Caucasian",
