How do I read R syntax code into a R session and obtain primers on other issues to get started with R?
You can store R code including function definitions in an ordinary text file and copy and paste into a R session. This means you retain a R program archive which can be easily adapted and quickly run in any R session.
Using source("filename.R") imports R code into R from a file called filename.R which may, for example, contain sets of functions.
For those wishing to get started using R some videos on particular aspects are available for viewing below. These videos have been put together by Dr. Thomas W. MacFarlane of Nova Southeastern University and illustrate and implement the R code for various analyses.
