Hi Matt, Thanks for the great tutorial. I hope you can help with my query. I am stuck with the step_dummy function. The script is running fine for me (see below) up until this point but it does not convert the categorical data into binary. I still only have 17 columns with 45k rows after running this. I have checked that my libraries are all the required versions and seem to have no issue there. Do you have any suggestions? Thanks Matt, John. recipe_obj % step_rm(ID) %>% step_discretize(all_numeric(), options = list(min_unique = 1)) %>% step_dummy(all_nominal(), one_hot = TRUE, naming = partial(dummy_names, sep = "__")) %>% prep()

Same issue here. PDAYS variable values is being collated into just one bin with one level. How'd you resolve this please?

Hello all, Thanks a lot for this tutorial. Please I have a question. I tried: map(sheets~ read_excel(path = path, sheet = .)) But got an error> Why is this so? I imagine thw "%>%"(pipe) just supplies the data to the nested function. How come it gives an error when applied directly?

Hi Onimisi, Please double-check the verified code against your code. You can see it here: github.com/business-science/presentations/blob/master/2019_02_13_Learning_Lab_Marketing_Analytics/marketing_analysis.R

Could you guys do something about the video's blurriness? After running each line of code, this error message comes up? Can you explain this error message? > # 3.0 PERFORM VLOOKUP EQUIVALENT ---- Error in exists(cacheKey, where = .rs.WorkingDataEnv, inherits = FALSE) : invalid first argument > data_joined_tbl % Error in exists(cacheKey, where = .rs.WorkingDataEnv, inherits = FALSE) : invalid first argument + map(~ read_excel(path = path, sheet = .)) %>% Error in exists(cacheKey, where = .rs.WorkingDataEnv, inherits = FALSE) : invalid first argument + reduce(left_join) Error in exists(cacheKey, where = .rs.WorkingDataEnv, inherits = FALSE) : invalid first argument

Try changing your quality from auto to a higher setting. KZitem defaults to lower resolution.

Hello, I am getting the following error for the one_hot=TRUE parameter in step_dummies: `TRUE` must evaluate to column positions or names, not a logical vector .

Hey Matt, Yeah I copied and paste the code and it gives me that error. I don't know if someone else has had this error. However, if I just use the code like this, recipe_obj % step_rm(ID) %>% step_discretize(all_numeric(), options = list(min_unique = 1)) %>% step_dummy(all_nominal())%>% prep() It works, the only thing I have less variables as you do because it is not using the one-hot encoding parameter. I'll try and find what possible error it could be.

Make sure you load the tidyverse library - library(tidyverse) You will need to install all of the packages with install.packages("package_name")
