This section shows how to solve the problems with the error message “replacement has X rows, data has Y”. In order to avoid this error, we first have to append a new column to our data frame that contains only NA values: data$x1_range<-NA# Initialize empty variable first ...
We proceed to teach how to do it in R. We already know the order of integration of each time series, so we continue with the rest of the steps: Step 1: Install and import the necessary libraries. Step 2: Import the data. Step 3: Create a dataframe to put together the adjusted clos...
