Description: This package is for calculation of BMI (body mass index),
    and some more computations based on weight loss goals. The package provides
    simple answers to a user's weight loss goals in terms of how much weight
    loss/gain and calorie deficit/increase should be aimed for with a target
    weight and time frame in mind. The package also provides helpful
    visualizations for these questions.

Review Comments

I would like to extend my sincere congratulations on the successful creation of your captivating package. The level of development and user-friendly features are truly impressive. I would like to offer some recommendations or comments for your consideration:

• I encountered error for running all functions in Jupyter Lab for this R pacakge.
  Please see the error message: Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): namespace ‘vctrs’ 0.5.1 is already loaded, but >= 0.5.2 is required
• It might be beneficial to include a clear link of doc in the README for reference.
• For similar packages listed in the README, maybe you can consider adding references to existing Python packages for comparison.
• Maybe it is better to include graphical examples in your vignettes to enhance the understanding of the package's functionality
• It might be a good idea to add https://www.nutristrategy.com/activitylist4.htm as a reference for exercise_plan in the README for added clarity.

Great job! It is a pleasure reviewing your package.

Review Comments

1. I really like the idea of this R package, it's straightforward, easy to use and understand.
2. When I try to create the plot for my BMI, it would be nice if there is any warning/log message printed out so that I know which parameter I might input wrongly.
3. Some characters in the plot are trimmed off, (e.g. "50" in the plot is missing on the right)
   
4. Would be nice if the package user can change the color of the plot which gives flexibility to the output plot.
5. I like that this team selected the Plotly package which is available in both Python & R and minimizes the code changes during development, great job.

Review Comments

• The usage and the outputs of the functions in R are consistent with the python version, which makes the user easily get familiar with both versions. Also, the similar coding style makes further implementation of the package easier
• The merge history shows the team did well on the version control, and the branch’s names indicate a reasonable work distribution among them.
• The R version of this package rounded calculated_bmi and other functions’ s output into two decimals, which is better than the python one.
• Good data visualization, a clear reflection of the health level interval of BMI, projected BMI trajectory and projected weight loss.
• Maybe giving a further explanation of the Body Mass Index graph is a good idea since some elements in the graph are not very straightforward for users to know immediately.

Review Comments

I'll start off by saying congratulations on completing this project and it was a pleasure to review your bmi.calculator package. Below I've listed some comments about aspects I believe were done very well and some areas for improvement:

• The README file was well written, information, and easy to follow. I also liked that you included links to various other documents in the repository for easy access; however, the figures could use some adjustments as certain bits are cut off ( e.g. the Body Mass Index one is missing the "50", other figures are cropped very close to the edge of the title)
• Overall, the repository is very well organized and "clean"; however, I would suggest deleting some of the merged branches if they are no longer necessary
• The package itself is very easy to use (especially when provided with the very detailed instructions in the README and documentation) and it also serves a useful purpose
• Good job on the testing of all of your functions as it was thorough and well thought out. Many tests were included for each function that covered a wide range of scenarios
• More of a small nitpick, but it appears that the vignette on the website is just a copy of the README (minus the suitability within R ecosystem, contributing, license, and credits sections). Perhaps it would be better to include a different example in the vignette with more explicit instructions provided

Overall, great work on the development of your package! Keep it up!
