**Analysis with R**, and kindly contributed to R-bloggers)To enter data into R, two common and easy to use R functions are utilized.

- The concatenate function,
**c**; and, - The
**data.frame**function.

The concatenate function,

**c**, is use for combining data points into a single numeric R object. The usage of this function is simply**c()**, the entries inside the parentheses will be the data points separated by comma. Below is an example of this,

The

**RData**above is a numeric R object with entries of the data points 36, 6, 15, and so on. This R object is then the data, and is ready for some tests.

The

**data.frame**function, on the other hand, is use for entering data into R object in data frame class. This will generate a table when applying**fix**function to it, which is used as data editor similar to that in Minitab and SPSS.

To do this, assign the variable name of the data first, say

**R.df**. Then run the following

The data frame class above is assigned to

**R.df**variable. Hence,**R.df**has this frame of data points. But because no data points were entered yet, then**fix**function is used to open the data editor and enter the data into this**R.df**data frame.
