My Goals in Data 101

  1. Build confidence with R and RStudio
  2. Understand how to explore and visualize data
  3. Complete a final project using real-world data

Here is a sentence with bold and italic words.

Task 2: Upload a built-in data set “mtcars”

Below, I load and inspect the built-in dataset mtcars, then compute the mean, max, and min of mpg.

```{r} message=FALSE, warning=FALSE} # The dataset is built into R; no need to load a file. # Display the mtcars data frame: mtcars

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:

summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

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