R if-nest 和/或 for 循环中的错误？ “}”中出现意外的“}”

Question

I'm trying to work with a table called 'data' in R .

My code is roughly like this:

for (i in nrow(data):1) {
  data$meanApproval[i] = mean(data[max(1,i-11):i,5])

  if(data$Poll = data[duplicated(data$Poll),]) {
    data = data[!duplicated(data$Poll),]
  }
}

It throws the error as in the title:

"Unexpected '}' in "}""

The syntax before I added this code gave no complaint, so I'm sure it's the section I've posted.

I know this may be considered a duplicate question, but I've studied all the other answers, and none of them help me with this issue. I can't find any missing bracket matches, and none of these are the result of a unicode misread.

Any help would be greatly appreciated.

Answer 1

The error message was misleading from the actual error in the code.

if(data$Poll = data[duplicated(data$Poll),]) {
...
}

should have read == for the if check

if(data$Poll == data[duplicated(data$Poll),]) {
...
}
