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:

sum <- 1
for(i in 12:1) {
  sum = sum * (i)
  print(sum)
  next
}

## [1] 12
## [1] 132
## [1] 1320
## [1] 11880
## [1] 95040
## [1] 665280
## [1] 3991680
## [1] 19958400
## [1] 79833600
## [1] 239500800
## [1] 479001600
## [1] 479001600

vec <- seq(20,50,by=5)
typeof(vec)

## [1] "double"

vec

## [1] 20 25 30 35 40 45 50

factorial <- function (a,b,c)
{
  sq = sqrt((b*b)-(4*a*c))
  sol1 = ((-1*b)+sq)/(2*a)
  sol2 = ((-1*b)-sq)/(2*a)
  answer = paste("The Solutions are ",sol1,",",sol2)
  return(answer)
}
factorial(1,4,3)

## [1] "The Solutions are  -1 , -3"

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.
