Hi there: I am a total beginner in R, and I have a simple question: I have a table with thousands of lines that represent locations, and two columns: latitude and longitude. I need to randomly sample 1000 lines. How do I do it? I know the command "sample", but it samples elements independently, not lines. If there is a better place for me to ask that type of question, please let me know. Thanks a lot, Mariana (from Brazil)
