R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r cars} # Load the Carseats dataset data(Carseats)

Fit a multiple regression model

sales_model <- lm(Sales ~ Price + Urban + US, data = Carseats)

Print the summary of the regression model

summary(sales_model) summary(sales_model) smaller_model <- lm(Sales ~ Price, data = Carseats) summary(sales_model) summary(smaller_model) confint(smaller_model) plot(smaller_model)

## Including Plots

You can also embed plots, for example:

```{r pressure, echo=FALSE}
plot(pressure)

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
