This is because you need this dataset included in your R Markdown document.

The first problem I see is that you shouldn't include install commands in your Rmd file, you only need to install packages once in your system, but if you include this command, you are going to be installing them every time you knit the document.

Now, about your issue, when you knit a document the code gets executed in a clean environment other than the one you are currently working on, so if you do not include the code you have used to load dailyActivity into memory, the dataset is not going to exist in the clean environment.

done please check if this is understandable

This is not valid R code, so you basically have the same problem as before. You need to include valid code to read your data frame into memory.
