From the post:
Always new software language in one technical activity is difficult, normally a good documentation can help, these are three book to use R software for beginner and for experts:
- “Introduction to the R Project for Statistical Computing for Use at the ITC” by David Rossiter (PDF, 2010-11-21).
- “R for Beginners” by Emmanuel Paradis (PDF,10 pages).
- A Little Book of R for Multivariate Analysis (pdf, 49 pages) is a simple introduction to multivariate analysis using the R statistics software. It covers topics such as reading and plotting multivariate data, principal components analysis, and linear discriminant analysis.
- A Little Book of R for Biomedical Statistics (pdf, 33 pages) is a simple introduction to biomedical statistics using the R statistics software, with sections on relative risks and odds ratios, dose-response analysis, clinical trial design and meta-analysis.
- A Little Book of R for Time Series (pdf, 71 pages) is a simple introduction to time series analysis using the R statistics software (have you spotted the pattern yet?). It includes instruction on how to read and plot time series, time series decomposition, forecasting, and ARIMA models.
