I'm doing some data analysis for a research project. Using the program R I'm trying to create level plots. Essentially 2D contour plots without the lines. I've trawled the Internet and tutorials for days and can only find tutorials that use data from a package. I have the raw data, x, y and z coordinates. I want to create level plots using the raw data. Can someone please walk me through the steps to use this program? Or point me to a good resource. I've never used the program before either btw. In the deep end. Thanks!
