Hi David,

This download course code worked on my personal mac, but I'm trying to get it working on my work Windows laptop. It keeps returning this error:

The downloaded binary packages are in
	C:\Users\bgunderson\AppData\Local\Temp\RtmpmQYDJV\downloaded_packages
> library(usethis)
Error: package or namespace load failed for ‘usethis’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
 there is no package called ‘vctrs’

Help me troubleshoot?

When I try to download the course project I keept getting this error message:

use_course("https://rfor.us/getting-started-materials") Error in use_course("https://rfor.us/getting-started-materials") : could not find function "use_course"

Hi David, I'm getting this error while downloading the project: trying URL 'https://cran.rstudio.com/bin/windows/contrib/4.3/usethis_2.2.2.zip' Content type 'application/zip' length 897217 bytes (876 KB) downloaded 876 KB

When I tried to manually type out the code, I got these: package ‘yaml’ successfully unpacked and MD5 sums checked package ‘usethis’ successfully unpacked and MD5 sums checked

I didn't get any of the 'yes' 'no' absolutely' options mentioned in the video- please help! Thank you!

I get an error "Error in library(usethis) : there is no package called ‘usethis’", it the file does not want to load for me

I would like to save the files to a different directory. I see "Prefer a different location? Cancel, try again, and specify destdir" I tried just running destdir 'C:/Users/myname/destination/' but that didn't work. Can you help? How do I "cancel"? Thanks!

install.packages("usethis") library("usethis") use_course("https:/rforus/getting-started-materials")

I wonder if it would be possible to modify the script so that the materials would be download in at already created directory. In my case "~/Documents/R-books/Getting started with R". I had already created a project jumping ahead the lesson.

I am having difficulty installing the example data. My error message is: Warning in install.packages : package ‘usethis’ is not available (for R version 3.4.1)

Is there another way for me to download the necessary files?

Hi, David. Thanks for this exceptional free resource on R. I am attempting to use R on my Chromebook. So far, so good. Just a note that, to successfully install the "usethis" package, I had to issue the following commands first:

sudo apt-get install libssl-dev install.packages("openssl")

I am keeping notes on modules I need to install in addition to your instructions in case this is useful for another student.

Thanks!

Hello David, how do I stay on course? I pasted the project link. And my PC took some time to process and I received this back : > install.packages("use this") Warning in install.packages : unable to access index for repository https://cran.rstudio.com/src/contrib: cannot open URL 'https://cran.rstudio.com/src/contrib/PACKAGES' WARNING: Rtools is required to build R packages but is not currently installed.

Hello, I have version 4.3.3, but I am getting the following error message:

Warning in install.packages :

When I run the project code it says it was successfully run but I don't see a question about whether to download to the desktop and I can't open the project folder to look at the files in it. I am using R 4.3.3. not R 4.2.2 as the video has it. I have no coding experience whatsoever.
