Introduction to R and Rstudio
The second one
Reading in data
Tidy data
Issues with this dataset:
- Doesn’t start in cell A1
- Column names don’t describe contents - information is missing. What do the numbers represent? Better column name would be ‘count’ or similar
- Used a mixture of words and numbers in a column
To make it tidy:
- Columns should be ‘batch’ and ‘count’ (or whatever is being measured)
- Start at cell A1
- How to deal with missing values? As a separate table?
- Or we could have batch 1 and batch 2 as two separate tables
