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.

## [1] 49

a
## [1] 2 5 6 7
class(a)
## [1] "numeric"
plot(a)

b <-as.numeric(c(1,0,9,8))
b
## [1] 1 0 9 8
class(b)
## [1] "numeric"
plot(b)

c <-as.numeric(c(6,5,8,3))
c
## [1] 6 5 8 3
class(c)
## [1] "numeric"
plot(c)
