意想不到的')，我想不通
我收到以下错误。我不知道缺少什么，因为我似乎所有的括号都匹配了。
错误：意外的“)”位于： “{ if (grepl(propertiesData[x,'city'],population[z,'NAME'],ignore.case=TRUE) & (propertiesData[x,'stateLong']==population[z,'STATENAME')"
这是循环的代码：
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
}
}
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
}
}

看来您忘记了右括号。添加它，看看会发生什么：
Seems like you forgot the closing bracket. Add it in and see what happens:
您在行尾缺少一个
]。...==人口[z,'STATENAME'] ))
You're missing one
]at the end of line....==population[z,'STATENAME'] ))
您在末尾缺少“]”：(propertiesData[x,'stateLong']==population[z,'STATENAME']))
You are missing "]" at the end : (propertiesData[x,'stateLong']==population[z,'STATENAME']))
