Sir, I have a question please. How to enter data? how to do a research and enter the data on excel
If your data are already in an Excel worksheet, you can analyze that data. If your data are not in an Excel workbook, you need to import them into Excel. Some files (like .csv files) can be opening by Excel. Sometimes you can copy data and then paste it into a worksheet. If you're working with a very small dataset, you can even type it directly into a worksheet.
I'm working on another video for the RCPA3 Package's getC function that shows you how to import datasets into R. You can find some additional tutorials on this topic here: www.poliscidata.com/pages/rDemosResources.php?chapter=15
Thank you.. I follow you from iraq
