# The following is fictional enrollment data for different majors in a liberal arts college
enrollment <- c(100, 250, 45, 95, 400)
major <- c("Political Science", "Math", "Anthropology", "Geography", "Economics")
Error: object ‘isFALSE’ is not exported by 'namespace:xfun'
Has anyone experienced this before? Every time I try this happens, regardless of what the contents of the chunk I am running are.
I tried many different notebooks running an Rmd file, but every time it did not work.

Reset to default 1You need to update your packages.
Searching the text of your error leads to this blog entry by the creator of the knitr package that has a longer explanation, but the lead is:
You probably came to this blog post due to an error related to
xfun::isFALSE(), and I strongly recommend that you update all your R packages:update.packages(ask = FALSE, checkBuilt = TRUE)That’s because the error is most likely to be from one of your outdated packages.
