Dear. All
Hi. While doing my assignment, I had an trouble. I tried to push the button, Knit to HTML. But, the message I attached was appeared. So, I can’t change my file to HTML. Could you tell me how to solve this problem?
You are being asked to install caTools package, try installing it with this command
install.packages("caTools")
Have in mind that caTools requires R >= 3.6 so if you have an older version you will need to update R first.
Thank you for your help. I think my version is old, so I typed install.packages(“installr”) on console. But I failed. At the same time, the message package ‘installr’ is not available (for R version 3.5.0). In this case, how can I update? Sorry for interrupting you.......I’m very beginner of it.....
Go to the CRAN site, download the corresponding version for your operating system and install it like you would install any other software.
