Every experiment starts with data, so the question is "how do you enter your data into R?". Well there are many ways to do that, but for this post, we will only consider the two functions below:

Where

What happened here is that, we defined a new object,

For dispersion, try this,

What about the

What we did here is we defined two R objects, the

And the mean of the

- The concatenate,
`c`

; and, - the
`data.frame`

functions.

`c`

, is use for combining data points into single numeric R object, known as the vector. The usage of this function is simply
Where

`...`

is the objects to be concatenated. Run `?c`

, for description of the second argument. Let's try an example,
What happened here is that, we defined a new object,

`vec1`

, into the workspace. We can then start manipulating the entries, say using the summary,For dispersion, try this,

What about the

`data.frame`

function? If the first function combines data points into a single vector, `data.frame`

from the name itself constructs a frame of data points. Here is an example,What we did here is we defined two R objects, the

`weights`

and `volunteers`

, then we combine the two into a table like structure, called the data frame. To extract columns of `data1`

, try this,And the mean of the

`weights`

is,
