In addition, you can follow these steps:

1. Data Structure in Excel:

- Each row represents a single study.

- Each column represents a variable or attribute of the study.

- Common columns may include study ID, treatment dosage, outcome measure, effect size, standard error, animal species, publication year, etc.

2. Data Import in R:

- Save your Excel file as a CSV file (comma-separated values).

- In your R script, use the `read.csv()` function to import the data into a data frame. For example:

```R
