Hi Hannu,
I figured out the problem. The following code works for me. Note that I
generally find it helpful to write function calls with the name of the
package they come from, as in ompr::MIPModel() rather than just MIPModel().
This is partly style and partly to avoid issues when functions get

I forgot to mention that I am using the ompr package. An example is given

I have tried to replicate Example 5.1 in Luenberger: Investment Science.
Here is the model
model <- MIPModel() %>%
add_variable(x[i], i = 1:7, type = "binary") %>%
set_objective(200*x[1]+30*x[2]+200*x[3]+60*x[4]+50*x[5]+100*x[6]+50*x[7])
%>%
