This is an R Markdown document. These all code are based on car dataset(default) .
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
Now here comes the all details of cars their speed and their dist

You can also embed plots, for example:
Now box plot for car speed:
boxplot(cars$speed , xlab = "variation " , ylab = "speed",horizontal = TRUE)
now the speed (histogram)
hist(cars$speed , col = "blue" ,main = "diagram for speed limits")
Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
