x <- c(1, 2, 3, 4, 5) 
```
Importing Data:
```
read.data("filename.csv") 
```

Statistical Analysis

Here are some simple commands for common statistical analyses:

Descriptive Statistics:
```
summary(x) 
```
Linear Regression:
```
model <- lm(y ~ x) 
```

Creating Graphs

Visualizing data is crucial. Here’s a command to create a scatter plot:

plot(x, y)

Intermediate Techniques

Once you feel comfortable with basic commands, you can explore more advanced features.

Multi-variable Analysis

Performing analyses involving multiple variables allows you to uncover deeper insights. Use the following command for a multiple regression:

model <- lm(y ~ x1 + x2 + x3)

Custom Functions

Creating custom functions can streamline repetitive tasks. Here’s an example:

myFunction <- function(x) {   return(mean(x)) }

Data Visualization Techniques

In addition to basic plots, you can create more complex visualizations:

Histograms:
```
hist(data) 
```
Box Plots:
```
boxplot(data) 
```

Advanced Techniques for Experts

Scripting

For advanced users, mastering the scripting language opens doors to a myriad of possibilities. Scripts can automate analyses or create specialized functions tailored to specific research needs.

Creating a script: Use the script editor to document your analyses for reproducibility.
Debugging Scripts: Utilize debugging tools to ensure your scripts run smoothly. Common issues include syntax errors or data type mismatches.

Statistical Modelling

Engage with robust statistical models using MacAnova’s scripting capabilities. Perhaps you want to implement a Bayesian approach or a complex mixed-effects model:

model <- bayesian.model(y ~ x + random_effect)

Solutions to Common Problems

When working in MacAnova, you may encounter common issues. Here are a few solutions:

Data Not Importing: Ensure the file path is correct and the data is formatted properly. Use the read.data function with appropriate arguments.
