The file "flowers.csv" file contains information on measurements of the iris flowers. Create an R data frame by the name "flower.data" that contains the data in the file.
The following R code shows an example of how to round a vector of numbers to zero decimal places and then calculate some statistics using the rounded numbers. You might need some of the calculations for this assignment, but you might not need others. You would replace example$years with the name of the R object that you want to analyze (in other programming languages, you might call example$years a variable).
