Example article

The data contained in the exampleRPackage R package was analyzed exactly like detailed in this document.

First, because the data is contained in a package, we can easily call it from R

library(exampleRPackage)
head(exampleData)

##   group     score
## 1     a  97.18260
## 2     a  86.87440
## 3     a 107.95184
## 4     a 102.70070
## 5     a  97.22694
## 6     a  94.33976

We drew a boxplot:

boxplot(score ~ group, data = exampleData)

And conducted a t-test:

t.test(score ~ group, data = exampleData)

## 
##  Welch Two Sample t-test
## 
## data:  score by group
## t = -3.1273, df = 57.854, p-value = 0.00276
## alternative hypothesis: true difference in means is not equal to 0
## 95 percent confidence interval:
##  -12.761430  -2.800308
## sample estimates:
## mean in group a mean in group b 
##        96.58283       104.36370

We also used the hello() function:

hello("my name")

## [1] "Hello, My Name"
