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.

for (i in 1:10){
  print(paste("i: ", i, i^2))
  1+1
  if (i==5){
    print(i)
  } else {
    # do nothing
  }
}

## [1] "i:  1 1"
## [1] "i:  2 4"
## [1] "i:  3 9"
## [1] "i:  4 16"
## [1] "i:  5 25"
## [1] 5
## [1] "i:  6 36"
## [1] "i:  7 49"
## [1] "i:  8 64"
## [1] "i:  9 81"
## [1] "i:  10 100"
