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:

convMeter<- function(val, to= "inch"){
  mult<-
    switch(to, inch=39.3701, foot=3.8084, yard
           =1.09361,mile=0.000621371,CM = 100,NA)
  if (is.na(mult))print("Unkown target unit of length,")else return(val*mult)
}
convMeter(23,"foot")

## [1] 87.5932

Inches= convMeter (40,"inch")
sprintf("40 metters are equilvalent to %f inches", Inches)

## [1] "40 metters are equilvalent to 1574.804000 inches"

convMeter(40)

## [1] 1574.804

convMeter(5,"CM")

## [1] 500

convMeter(2.4,"km")

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.
