Does anyone else have problem loading the caret package in R?

When i tried to install the package, the following error message shows up:

Error: package or namespace load failed for ‘caret’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
namespace ‘Rcpp’ 0.12.17 is already loaded, but >= 1.0.1 is required

What am I not doing correctly to cause this? Thanks!

Looks like you need to update R or RStudio, or both. Here's a link on how to update R using RStudio:

Also, to update RStudio, go to Help > Check for Updates and download the newest version if you don't have it installed already.

It keeps on saying "Switching to project ~/Desktop/checkp5" but it never loads the project.

Still unsure what I did wrong, I even followed the video walkthrough to try to set it up. Tried updating my macOS and reinstalling Rstudio but still, no luck
Did you get this figured out? My MacBook does the same thing then it randomly just closes out of R.

Please follow the below instructions. Worked for me.

I'm running R 3.6.1 and RStudio 1.2.1335 on a 2017 Macbook Pro.

Step 1 - Download the checkp5_mac.zip file from Module 1.

Step 2 - Go to your Finder and locate the folder where you downloaded the file. Extract the folder. Now press Command + Shift + . [command + shift + period]. This makes the hidden files visible.

Step 3 - Go down this file path through the now visible folder: ‎⁨⁨‎⁨⁨checkp5⁩ ▸ ⁨.checkpoint⁩ ▸ ⁨2018-06-01⁩ ▸ ⁨lib⁩ ▸ ⁨x86_64-apple-darwin15.6.0⁩

Step 4 - Here, you should find a folder named 3.5.0. Make a duplicate of this folder and rename it 3.6.1

Step 5 - Now continue with step 5 of the Installing the Frozen Version steps in Module 1. When you do step 8, it should finally open the checkp5 project in RStudio. My computer took about 20 seconds to make the switch.

The issue seemed to be the checkpoint function (which is called through the .RProfile file upon opening the checkp5 project), which gets hung up trying to install packages since they aren't already included in the version folder. The first time I tried following the module instructions, I left my computer overnight and it was STILL spinning its wheels the next morning.

Hopefully this helps someone! Fingers crossed we don't run into anymore issues down the road.

SOA has the exam dates as Dec 12-13 - does anyone know if we can be sure that we'll be sitting on the 12th? I am planning a flight for the very next day and want to be totally sure I won't have to sit for PA on the 13th instead.
The Dec 2019 exam is now open for registration. Here is the link: https://www.soa.org/Education/Exam-R...analytics.aspx.

I just registered through the SOA website; haven't taken a CBT exam in a while. I'll have to wait for an email and then schedule it, right? Is that how it works?

Correct- you will get an email directing you log on to the prometric site to schedule

Has anyone successfully booked at a Prometric exam center for December? I registered on 10/1 and received the email from Prometric today. I have checked at least 10 centers in NH, MA, NY, ME, and Montreal. It shows that there are no available openings at any of them in December.

I'm wondering is something is messed up at Prometric, because these can't all be booked already. So has anyone else actually registered?

I have the same problem (Montreal, Quebec, Ottawa). I don't understand why. It can't be already full...
