To ensure a particular data value gets mapped to particular color, provide a character vector of color codes, and match the names attribute accordingly. When doing a line chart, it is sometimes difficult to visualize where the breaks in the curve are, and thus when the observation have been done. data gives the object name of the data frame. In R, the standard deviation and the variance are computed as if the data represent a sample (so the denominator is $n - 1$, where $n$ is the number of observations). labels), color can be used to represent continuous or discrete data.
