R随机森林求助

library( ”randomForest” )
training <-read.csv("d:/Users/Lenovo-pc/Documents/2013data1.csv",header=TRUE) /导入数据/
ind <-sample(2,nrow(training),replace=TRUE,prob=c(0.7,0.3)) /对数据分成两部分，70%训练数据，30%检测数据/
traindata<- training [ind==1,]
testdata<- training [ind==2,]

set.seed(100)
rf<-randomForest(one year~.,data=training,iris[ind==1,],ntree=100,nPerm=10,mtry=3,proximity=TRUE,importance=TRUE)

table(predict(rf), training$id)
print(rf)
plot(rf)

代码显示错误: unexpected symbol in "rf<-randomForest(one year"
但是我的csv表格中是有one year这一列的，请问问题出在哪里？ :cry: :cry: :cry:

改为：rf<-randomForest(oneyear~.,data=training,iris[ind==1,],ntree=100,nPerm=10,mtry=3,proximity=TRUE,importance=TRUE)之后，显示：

Error in na.fail.default(list(oneyear = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, :
missing values in object
这个是什么意思？
:?: :?: :?:

啊那个是数据集，写错啦，可我改成rf<-randomForest(oneyear~.,data=training,training[ind==1,],ntree=100,nPerm=10,mtry=3,proximity=TRUE,importance=TRUE)
之后也是
Error in na.fail.default(list(oneyear = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, :
missing values in object
