Example text

UseMethod("plot") plot <- 5 plot [1] 5 In the first instance, R finds plot in the graphics package. In the second instance, R finds plot in the global environment. Note that assigning 5 to the variable, plot, does not overwrite the plot() function. Instead, it creates another R object with the same name as the function. After creating the new variable, when we type plot at the console, R returns the numeric value rather than the function because the assignment, plot <- 5, occurs in the global environment, which R searches before it checks the environments of different packages.

One of the reasons it is helpful to use warnings or messages, rather than just calling print() or cat() to have the function print a message, is that warnings and messages can be (optionally) suppressed by using the aptly named functions suppressWarnings() and suppressMessages().

We show the code as follows, along with Figure 3-2, which is the output of the successfully executed if portion: if(mean(y)>6){ + boxplot(y) + } else{ Error: unexpected 'else' in "else" histogram(y) } Error: unexpected '}' in "}" 33 CHAPTER 3 ■ PROGRAMMING AUTOMATION Figure 3-2.
