解析误差Rmd

Question

我试图编织我的Rmd文件，我得到了这个错误。

Error in parse(text=x,srcfile=src): <text>:5:51: unexpected symbol 4: pred_test = predict(ames.bas,newdata=ames_test,estimator="BMA")5:resid_test=ames_test$price-exp(pred_test$fit) rmse_test

它停在第402行：

```{r}rmse_train = sqrt(mean((na.omit(ames_train$price - exp(pred_train$fit)))^2))

rmse_train

ames_test = ames_test %>% filter(邻居!= "Landmrk"，Sale.Condition == "Normal")

pred_test =预测(ames.bas，newdata=ames_test，估计量= "BMA")

resid_test = ames_test$price - exp(pred_test$fit) rmse_test =sqrt(resid_test^2)

resid_test

``` How can I resolve this problem? I tried everything that I could find among the answered questions

Answer 1

我假设这是因为在一行上有2行代码。

resid_test = ames_test$price - exp(pred_test$fit) rmse_test = sqrt(mean(resid_test^2))

应该是

resid_test = ames_test$price - exp(pred_test$fit) 
rmse_test = sqrt(mean(resid_test^2))
