The lines above are two complete statements.
else {
The else is not allowed to start a statement. You need to make sure
the if is incomplete when you start the line containing else. The
usual style is
if (cond) {
stmt1
# The if is still incomplete, because the closing brace is missing
} else {
# now the else will be accepted
stmt2
}

Reformatting your code (for readability) but preserving your
line breaks:
invalid.ids - c(1,3,5)
if (length(invalid.ids)==0) {
cat(No Errors found)
}
else {
cat(paste(invalid.ids), sep=\n)
} }
Error: unexpected 'else' in else
Error: unexpected '}' in }
First:
The first four lines are a completed command, given the way
that R parses input. After encountering the end-of-line at
the fourth line, R considers that it has seen a complete command
and therefore executes it.
invalid.ids - c(1,3,5)
if (length(invalid.ids)==0) {
cat(No Errors found)
}
Therefore the else { on the next line is not interpreted as
if it were part of the preceding if() statement, since that
has been considered complete and has been executed. So that
else is an else with no matching if. Henc the the first
error message.
Second: if you count the opening { and closing }, you will
see that there is one } too many, at the end, hence the second
error message.
The way to avoid the first error message is to put the else
on the same line as the close of the if statement. Then R will
recognise that it has an incomplete commend, and continue to parse
further input until it has built up a complete command. So you
should write:
invalid.ids - c(1,3,5)
if (length(invalid.ids)==0) {
cat(No Errors found)
} else {
cat(paste(invalid.ids), sep=\n)
}
(Note that the extra } has been omitted too).
Hoping this helps,
Ted.

And now it is easy to see why we should all the one true brace style ;-)

Re: [R] Can anyone help why the errors are coming and rectify it?
Now i know why using else never worked for me - really, i'd consider this more
of a bug than a feature of the language ;)

Python doesn't, but then again, they don't have braces so the parsing is easier (i.e., there exist universalizable rules) Michael On 17.09.2012, at 14:35, R.
