Palmerpenguin dataset not loading correctly with skim_without_charts() function.

Hello, please, I am newbie on Rstudio, and I encountered the following difficulties below: Kindly assist me and advise on further steps to take in order to overcome my challenge in this instance. Thanks you.

1. Steps taken to install, load and use the 'Palmer penguins' dataset.

install.packages("palmerpenguins")

2. I decided to check for the dataset further using the installed. packages () function
installed.packages() gave the information below:

palmerpenguins NA NA NA "no" "4.2.1"
[ reached getOption("max.print") -- omitted 76 rows ]

Hi @Yvy !

When you install the palmerpenguins package, it downloads two csv files to the package directory.

Before you do anything to the data, you'll need to pull in the csv files to R.

First get the filepath to the first csv by running this line:

palmerpenguins::path_to_file(path = "penguins.csv")

Then once you have the filepath (note: should looks something like this: "/Library/Frameworks/R.framework/Versions/3.6/Resources/library/palmerpenguins/extdata/penguins.csv"

Paste that into the read.csv() function that is defining a dataframe:
penguins <- read.csv("the-copied-filepath-from-previous-step/penguins.csv")

In this case, I named the dataframe penguins, so I can now check out the data with something like head(penguins) or View(penguins) to make sure that it got pulled in properly.

To get the second csv file, called penguins_raw.csv all you need to do is create another variable, say penguins_raw to make it simple, and pass the read.csv() function the same filepath, but change the last bit to penguins_raw.csv instead of just penguins.csv.

Then you'll have all the penguin data! If you run into other similar issues, the help pane in RStudio is very helpful. Clicking on the packages tab in RStudio will take you to the list of packages you have installed. Search for palmerpenguins in there and click on it. It will have relevant information on how to use the package and other functions included in it.

Hope that helps!

Thank you so much, Jonesey441,
Your response was both timely and helpful!

In my experience, once the {palmerpenguins} package is loaded the penguins data frame should be available without any further steps.

skim_without_charts(palmerpenguins) did not work because that function is for a data frame, not a package. skim_without_charts(penguins) and skim_without_charts(penguins_raw) should both work.

For the reprex below I used the summary() function instead because the {skimr} package is not installed on this computer.
