Hi Susan,

Just a note that the datascienceplus version published is missing complete %>% operators beginning where you introduce them, and viridis.

Thanks for the analysis!

Dear @susanli2016 ,

Hi,
What formulas did you use to get blood glucose levels?

please guide me.
Thanks.

Hi! I'm working through your text analytics code with my own data set (One focused on social reviews from multiple sites for a specific brand). But I keep getting an error when trying to create the slopes that you use to map out the trend in word usage.

This is the code:

slopes <- word_month_counts %>% nest(-word) %>% mutate(model = map(data, mod)) %>% unnest(map (model, tidy)) %>% filter(term == "year") %>% arrange(desc(estimate))

And this is the error I'm getting:

Error in map(model, tidy) : object 'model' not found
In addition: Warning message:
All elements of ... must be named.
Did you want data = c(month, n, month_total, percent, year)?

Any idea on what may be going on? I could share more information if this isn't enough. Everything prior to this point has worked, although I've had to replace some minor terms such as column names

Can u share it with me? Thanxxxx!
