Code Chunks

When knitting the added code chunk (the one where we used the skim() function) I got a different-looking result as the one demonstrated on the solution video, more "polished" looking, and I'm not sure why.

Hi David,

The links for both these sections don't work: On another note, if you have issues getting the histograms to display properly and you’re using Windows, there is a known issue. Please see the skimr documentation for potential solutions.

Thanks, Atty

My html output (after checking that my code is exactly the same as the example solution), also looks more 'polished'... there are no hash tags and the font is the report font, not the code font, and a few other differences. The warnings are not shown in the report, even before adding 'warning = FALSE, message = FALSE' Not sure what I would need to do to make the warnings/messages appear in the report.

Hello, I did the steps but having error messages. So I went ahead and install tydiverse still not work.

• My codes install.packages("tidyverse")

library(skimr)
skim(cars)

Hi David, similar to notes below, the report looks more polished, no ## and stuff.

Getting this error when I try to due Include=False: > ```{r cars, include=FALSE} Error: attempt to use zero-length variable name

Everything worked for me except the include = FALSE. The output never went away. I did not get any error message, the output just remained.

Is there a video in this section?

Yesterday something happened with videos, but now it is working!

Hello everyone! I know that we don't go super in-depth with R-Markdown in this class but I was wondering what would be a scenario for giving a code chunk a name? Is it for reusability purposes if you need the same graph multiple times in a report?

Where do the data for cars and for pressure come from? I don't see them in the getting-started-master folder, nor in the faketucky dataset. summary(cars) is clearly calling that data, but I don't see how. :-) Thanks!

Is there a way to knit code automatically every time it is run?

Similar to what others have commented, I get a more polished looking result from the cars skim. No warnings or messages, no hashtags, and it has a data summary at the top (telling the number of columns and rows). I'm using a Mac. It doesn't seem like there was ever a definitive answer to what others said about this, and maybe it doesn't matter, but it is a bit puzzling.

I kept getting errors until I put my library request on the same line as the R code line. Is that strange?

Hello David. when i install new chuck and run skimr, i didnt get the summary report as in solution you provide

The warning message about the version disappeared when I uninstalled the version I was using and installed a recent version.
