R: kmeans on matrix (100x21)

I have a question about Kmeans in R. I have a dataframe like variable data_file. My question is, how can I perform kmeans on my data? If anyone has any suggestion, you are more than welcome. Thank you!

> data_file

Did you try the built in function kmeans?

kmeans(USArrests, centers=3)

USArrests is just a data set that comes with R.

If you google R kmeans you will get more information.
