Prediction using saved model object

Question

I am trying to use predict function in R using a model saved earlier. The model was created and saved using the following code: ``` lrModel1 <- glm(response ~ .,data = modelData,family = binomial,model = TRUE) save(lrModel1,file = "lrModel100.rda") ``` When I load the model for later use as follows and try to use the predict function on it as follows: ``` bar <- load("lrModel100.rda") predicted <- predict(bar,validationData,type = "response") ``` I get the following error: ``` Error in UseMethod("predict") : no applicable method for 'predict' applied to an object of class "character" ``` Is there a way to get the model object name from the saved RDA file and use it for prediction? Thank you. Ravi

Accepted Answer

As @droopy told you the model's name doesn't change if you save and load. You can use `get` to use the model:

```
predicted <- predict(get(bar),validationData,type = "response")
```
