R is a popular alternative to SAS, especially for those who cannot afford the latter or do not have access through their educational institutions. While SAS is highly regarded and sometimes required by certain programs, many professionals, including those at a national nuclear lab, utilize R for data analysis. Additionally, R is the standard in the Applied Math department at a well-known math and science university, indicating its credibility and acceptance in academic and professional settings. This suggests that R can be a viable and effective option for data analysis, particularly for students and professionals seeking cost-effective solutions.
