The traditional if-else construct in [[R (programming language)|R]] (which is an implementation of [[S (programming language)|S]]) is:

<syntaxhighlight lang="rsplusr">

if (a < b) {

x <- "true"

Line 627:

If there is only one statement in each block, braces can be omitted, like in [[C (programming language)|C]]:

<syntaxhighlight lang="rsplusr">

if (a < b)

x <- "true"

Line 636:

The code above can be written in the following non-standard condensed way:

<syntaxhighlight lang="rsplusr">

x <- if (a < b) "true" else "false"

</syntaxhighlight>

Line 642:

There exists also the function {{code|ifelse}} that allows rewriting the expression above as:

<syntaxhighlight lang="rsplusr">

x <- ifelse(a < b, "true", "false")

</syntaxhighlight>
