    Some of your rmarkdown code blocks are using three single-quotes `'''` for code-fences, those are incorrect. It needs three backticks `\`\`\`` instead. – r2evans Sep 23 '21 at 18:29
  • Got it! I changed that. My teacher said to use mean (dat$object1) and I just tried it and it didn't work... is there something I need to add to it? Like backticks? – Gracie Hobby Sep 23 '21 at 18:38

    *"It didn't work"* says nothing. Did it emit a warning or error? Did R or your operating system crash? Did the neighborhood lights dim? The *picture* (not good) of your data suggests that it is named `mydata` and not `dat`. Welcome to SO, Gracie Hobby! Please learn how to make questions a bit more reproducible by including sample data and code you've attempted; see https://stackoverflow.com/q/5963269, [mcve], and https://stackoverflow.com/tags/r/info for good discussion. Also, no pictures of data please, just *real data* (https://meta.stackoverflow.com/a/285557). – r2evans Sep 23 '21 at 18:54
  • Please provide enough code so others can better understand or reproduce the problem. – Community Sep 25 '21 at 01:36

dat$object1 refers to a column named object1 in a data frame named dat. Judging from the picture, you don't have a data frame named dat. However, you do have a column named object1 in your data frame. You need to change the first part of dat$object1, to make it refer to your data frame. Once you have made that change, you can put it inside mean().
