我使用以下脚本来计算R中的AUC：
library(mgcv)
library(ROCR)
library(AUC)
data1=read.table("d:\\2005.txt", header=T)
GAM<-gam(tuna ~ s(chla)+s(sst)+s(ssha)+s(eke), family=binomial, data=data1)
gampred<- predict(GAM, type="response")
rp <- prediction(gampred, data1$tuna)
auc <- performance( rp, "auc")@y.values[[1]]
auc
roc <- performance( rp, "tpr", "fpr")
plot( roc )
但是当我运行脚本时，结果是：
rp <- prediction(gampred, data1$tuna)
Error in prediction(gampred, data1$tuna) :
Format of predictions is invalid.
auc <- performance( rp, "auc")@y.values[[1]]
Error in performance(rp, "auc") : object 'rp' not found
auc
function (x, min = 0, max = 1)
{
if (any(class(x) == "roc")) {
if (min != 0 || max != 1) {
x$fpr <- x$fpr[x$cutoffs >= min & x$cutoffs <= max]
x$tpr <- x$tpr[x$cutoffs >= min & x$cutoffs <= max]
}
ans <- 0
for (i in 2:length(x$fpr)) {
ans <- ans + 0.5 * abs(x$fpr[i] - x$fpr[i - 1]) *
(x$tpr[i] + x$tpr[i - 1])
}
}
else if (any(class(x) %in% c("accuracy", "sensitivity", "specificity"))) {
if (min != 0 || max != 1) {
x$cutoffs <- x$cutoffs[x$cutoffs >= min & x$cutoffs <=
max]
x$measure <- x$measure[x$cutoffs >= min & x$cutoffs <=
max]
}
ans <- 0
for (i in 2:(length(x$cutoffs))) {
ans <- ans + 0.5 * abs(x$cutoffs[i - 1] - x$cutoffs[i]) *
(x$measure[i] + x$measure[i - 1])
}
}
return(as.numeric(ans))
}
<bytecode: 0x03012f10>
<environment: namespace:AUC>
roc <- performance( rp, "tpr", "fpr")
Error in performance(rp, "tpr", "fpr") : object 'rp' not found
plot( roc )
Error in levels(labels) : argument "labels" is missing, with no default**
有人可以帮我解决这个问题吗？ 提前谢谢。

答案 0 :(得分：0)
您的data1数据框已经搞乱了。看看str（）给你的是什么：
> str(data1)
'data.frame': 100 obs. of 1 variable:
$ x.y.chla.sst.ssha.eke.tuna: Factor w/ 311 levels "140.01178,44.666668,0.21406905,19.939999,6.931947586,213.8725429,87",..: 3 2 1 6 5 4 9 8 7 12 ...
当你实际上是一个包含单列的数据框时，你可能会认为这是一个带有numericcolumns的数据框。你似乎没有使用正确的'sep'参数就使用了read.table。列名全部组合在一起，值被捆绑在一起作为单个因子串。真糟糕！
最好是回到开始并重做read.table努力。我想可以解析单列的名称，然后在发送因子列的as.character（）结果上使用read.table，但这似乎是巴洛克式的。
编辑评论：我也认为大多数人选择AUC工具真的不明白它提供什么。它似乎比它应得的使用频率更高。
