Full_Name: Jens Lund
Version: 1.3.1
OS: Windows
Submission from: (NULL) (194.239.194.210)
Whitespace matters in else constructions; a newline does not seem to be allowed
in front of else:
# Valid input examples
if (F) {
print(T)
} else print(F)
if (T) print(T) else print(F)
if (F) {print(T)
} else print(F)
# Invalid input examples
if (F) {
print(T)
}
else print(F)
if (F)
print(T)
else print(F)

This is a documented feature: more accurately, newlines matter. An R statement is terminated if it is syntactically complete at the end of the line. See the reference manual section 10.2.5 for an explicit statement.
