if.R: 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.

Value

The result of the executed expression.

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.
