Visualizing the hashing
It is often helpful to look at a visual representation of your data. The baked
tibble is loaded with the hash indexes representing the EducationField
factor. You can explore all or a portion of this dataset as a matrix to identify patterns or detect potential errors.
The plot.matrix
package has already been loaded for you.
This exercise is part of the course

Exercise instructions
- Convert the baked
tibble
to a matrix. - Plot the
attrition_hash
matrix.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.

attrition_hash <- ___(baked)[1:50,]
# Plot the attrTheTition_hash matrix
___(attrition_hash,
col = c("white","steelblue"),
key = NULL,
border = NA)
