Attempt to apply non- function, randomForest

I have a data set(train2) with 79 variables(numeric and text combined) and the SalePrice as the last column. I am trying to create a randomForest model, this is what I get as an error:

Forest <- randomForest(SalePrice~., data = train2, na.action = TRUE)

Error in model.frame.default(formula = SalePrice ~ ., data = train2, na.action = TRUE) : 
attempt to apply non-function

Do you have any idea how I can solve this error?

@joran is correct. I also want to steer you in the direction of exploring these two:

ntree Number of trees to grow. This should not be set to too small a number, to ensure that every input row gets predicted at least a few times.

mtry Number of variables randomly sampled as candidates at each split. Note that the default values are different for classification (sqrt(p) where p is number of variables in x) and regression (p/3)
