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:
5 + 3
## [1] 8
sqrt(9)
## [1] 3
a <- 3
a
## [1] 3
b <- 4
c <- a + b
# This is use of operators
c <- a + b
c <- 5
c
## [1] 5
dd <- c(1, 2, 3)
Fra <- c("Frank", "jim", "Joe")
Fra
## [1] "Frank" "jim" "Joe"
You can also embed plots, for example:
plot(FALSE)
Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
