R Markdown

This is a sample document, the following is demographic data

age<-c(34,54,67,52)
person<-c("Frank", "Betty", "Juan", "Lisa")
sex<-c("M", "F", "M", "F")

df<-data.frame(person,age,sex)

#male and female are factors, they are one of two possible assignemnts for a particular 
#person who is mentioned on the dataframe. It is a factor with two levels

df$sex<-as.factor(df$sex)

#In the following part we are adding a column to determine whether or not a person smokes
df$smoking<-c("yes", "no", "no", "yes")
df$smoking<-as.factor(df$smoking)

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.
