if.R: Conditional Execution for R or S-Plus

In HH: Statistical Analysis and Data Display: Heiberger and Holland

Conditional Execution for R or S-Plus

Description

if.R uses the is.R function to determine whether to execute the expression in the r argument or the expression in the s argument.

Usage

if.R(r, s)

Arguments

r	Any R expression, including a group of expressions nested in braces. Assignments made in this expression are available to the enclosing function.
s	Any S-Plus expression, including a group of expressions nested in braces. Assignments made in this expression are available to the enclosing function.

Details

Not all functions are in both implementations of the S language. In particular, panel functions for lattice in R (based on grid graphics) are very different from panel functions for trellis (based on the older graphics technology) in S-Plus.

Value

The result of the executed expression.
