Question

I am getting the following error. I can not figure out what is missing, as I seem to have all my brackets matched up.

Error: unexpected ‘)’ in:
“{
if (grepl(propertiesData[x,’city’],population[z,’NAME’],ignore.case=TRUE) & (propertiesData[x,’stateLong’]==population[z,’STATENAME’)”

Here is the code of the loop:

for (z in c(1:nrow(population)))
{
    if (grepl(propertiesData[x,'city'],population[z,'NAME'],ignore.case=TRUE) & (propertiesData[x,'stateLong']==population[z,'STATENAME'))
    {
        propertiesData[x,'population']=population[z,'POP_2009']
        break
    }
}

Answer 1

==population[z,'STATENAME'))

Seems like you forgot the closing bracket. Add it in and see what happens:

==population[z,'STATENAME']))
