Getting Data into R

Datasets are frequently given as Excel worksheets. We must transfer them from Excel to R in order to place the variable names on the Rcmdr menu items. We show how to do the transfer for several different data structures. Sometimes datasets are given as ASCII text files. These too can be read into Excel and then transferred to R. Sometimes datasets are already in R. We can work with them directly, and we can display them in Excel by transferring the data the other direction from R to Excel.
