This comment was supposed to go under "start a new project" my bad

Hi Bhumika! It might be that you are not working on the same directory. Can you share on Discord a screenshot of your session? When this happens to me, I usually start running these codes on the terminal, just to quickly check if I'm working in the right place.

get_wd() # to get the exact directory I'm working on
dir() # to check the files on my current directory

You can inspect that using the posit interface too! For example, your working directory will be displayed on your console panel along with your R version.

Let me know if this helps and ping me on Discord to let me know how it went! =D

I think we got it worked out in office hours! Just needed to have the project open in order for the code to run.

For some reason, the tidyverse package didn't install correctly. It looks like this is because one package as part of the tidyverse didn't successfully install. Please run this in the console and then try again:

install.packages("utf8")

Let me know if that helps! Your other question should also be solved by this.

Hi, it worked! Thank you so much!

Hello, I got the same error and when I tried installing the package, it tells me package 'uft8' is not available for this version of R

What version of R are you using? If it's older, you may need to update it before installing the package.

I am using Version 2023.12.0+369 (2023.12.0+369) on my MacOS Catalina 10.15.7

Nevermind I figured it out!

Nevermind I figured it out!

I'm not quite sure I understand your question. Can you elaborate please?

I am sorry that I was not clear enough. I was wondering why sex was not loaded, despite its being a character. Also age not loaded and it is a dbl just like the weight that was loaded. Thank you

What is happening is that RStudio only shows the variables that can fit on the screen. If you click on the object in the environment pane you can see all of the variables. Does that help?

Are you sure you're working in a project? My guess is you're not. Can you please review this lesson and then confirm whether you're working in a project?

Hi, there! You'll need to use quotation marks around the file path, so try running: read_csv("penguins_data.csv")

Hi, Kendra! Can you share the code that you ran? It sounds like R was looking for an object, not a file, which means you may have run the code without quotation marks around the file path. Try running read_csv("penguins_data.csv") instead of read_csv(penguins_data.csv).

Hi Libby, Yes that was the case. I figured out right after I sent the message. I did not have quotations. Thanks.

Are you working in an RStudio project? Please review the Projects lesson if you need help figuring out whether you are.

(I am in the Import Data lesson)

Please disregard. I had to go back to the Projects lesson and re-run the “usethis”, etc., instructions so the getting-started-materials installed correctly. Works good now.

Something happened when you tried to install the tidyverse package. Please run install.packages("tidyverse") (which will also install `ggplot2') and try again. Hopefully this solves it for you!

I am still getting the same error response after I re-installed tidyverse.

Try running install.packages("ggplot2") and let me know if that works.

When I do that this message comes up:
There is a binary version available but the source version is later: binary source needs_compilation ggplot2 3.4.4 3.5.1 FALSE installing the source package ‘ggplot2’

So I'm still getting an error when I try to install ggplot2 and if I try to run library(tidyverse) the same error message about ggplot2 is still coming up.

Hmm, let's try having you start from scratch. Run remove.packages("tidyverse") to uninstall the tidyverse. Then, try running install.packages("tidyverse") and let me know if that works.

I uninstalled then reinstalled and this message came up: Error in install.packages : Updating loaded packages

Restarting R session...

It then installed the tidyverse package and even said this under: also installing the dependency ‘ggplot2’

BUT if I try to run library(tidyverse) again I still am getting the same error: Error: package or namespace load failed for ‘tidyverse’: .onAttach failed in attachNamespace() for 'tidyverse', details: call: library(pkg, lib.loc = loc, character.only = TRUE, warn.conflicts = FALSE) error: there is no package called ‘ggplot2’

This is very odd. Can you please run the function sessionInfo() and paste what is returned?

Could you try downloading the latest version of R and then reinstalling the tidyverse?

It worked! Thank you!

Hurray!

Good question! The read_csv() function will not drop the entire row. It will just mark the variable in that row as NA. If you have other questions, let me know!

Hi Bryan! Does that happen when you select the whole code and run it? Please feel free to copy your whole script here to help us debug!

I figured it out. I assumed hitting "Run" ran all of the code, only to learn it only does 1 line at a time. Once I hit "Run" again it opened the CSV file no problem.

Is there a way or a Mac shortcut to run all the code instead of line by line?

Yes! You can select the part of the code you want to run and press the same button, or use the shortcut Cmd+Return. You can also run the whole script at once using the button "Source" or the shortcut Cmd+Shift+Return. More shortcuts here: https://support.posit.co/hc/en-us/articles/200711853-Keyboard-Shortcuts-in-the-RStudio-IDE

You can also access the shortcuts panel on RStudio with the shortcut Option+Shift+K 😅

Hi Cesar! The error message hints that your read_csv() function is not written correctly.

Error: unexpected symbol in "read_csv(not read.csv" read_csv("penguins_data.csv")

Because the error message points out specifically to read_csv(not read.csv, you know that the error is there somewhere.

You've written the function name correctly, so it's not the read_csv( part. However, after the opening parenthesis, you've added an unrecognized element, not read.csv . Here you can find the arguments that can be used in the read_csv() function: https://readr.tidyverse.org/reference/read_delim.html

Therefore, you need to rewrite your function so it contains, in this case, only the file name: read_csv("penguins_data.csv")
