I started using R several years ago to analyze data I had collected for my research in graduate school. My motivation at first was to escape from the restrictive environments and canned analyses offered by statistical programs like SPSS. And even better, because it’s freely available, I didn’t need to convince someone to buy me a copy of the software— very important for a poor graduate student! As I delved deeper into R, I discovered that it could also create excellent data graphics.
