Could you explain the meaning of "custom CSS" better, please?

Sure! We often use .Rmd to create HTML output (reports and presentations). HTML is the language used to write web pages, each web page is a .html file containing HTML code. Here is an intro guide to HTML.
However, when it comes to styling HTML content we use CSS. In the CSS language we (for instance) specify that paragraphs should be indented, have double line spacing and should be in a particular font. This guide walks through how to add CSS to an RMarkdown document.
Let me know if you have follow up questions. Cheers, Charlie

If I want to download the package, the link above send you to a page with this information: Package source: NHANES_2.1.0.tar.gz Windows binaries: r-devel: NHANES_2.1.0.zip, r-release: NHANES_2.1.0.zip, r-oldrel: NHANES_2.1.0.zip macOS binaries: r-release (arm64): NHANES_2.1.0.tgz, r-oldrel (arm64): NHANES_2.1.0.tgz, r-release (x86_64): NHANES_2.1.0.tgz, r-oldrel (x86_64): NHANES_2.1.0.tgz
which one should I install (I am using Mac) and what are the binaries options that are there? or should I only: install.packages("nhanes") in the console?

Hi Nadia,
You can use install.packages to install the package, but please not that ALL R code is case sensitive. You will need to run
install.packages("NHANES")
Thanks, Charlie

Hello! I am having a blast working through this course. Especially the NHANES data wrangling section (this is exactly why I wanted to learn R)! I was having trouble creating a new variable based on another preexisting variable, then I realized that some of the variable field names in the NHANES dataset have changed since this tutorial was created. I was able to discover this by using the view() function. I updated the variable name in my code and voila! Simple fix! I'm already using the tools I've learned in this course and feel so accomplished being able to troubleshoot already!! Many thanks to the R for the Rest of Us team!

Did you download the course materials? If so, you'll need to open the project that was downloaded (look for the .Rproj file and double click it to open the project).

Hi. I am trying to update my packages in R as directed in the video above. I get the following error message (in red): Error in gzfile(file, mode) : cannot open the connection In addition: Warning message: In gzfile(file, mode) : cannot open compressed file 'C:\Users\paquinan\AppData\Local\Temp\RtmpoFAckU/libloc_185_13d200b7.rds', probable reason 'No such file or directory' I have no idea what this means, but it does not look good. What should I do?
