I am not able to knit my markdown. When I try to, I get this Error:
Line 9 Error in contrib.url(repos, "source") : trying to use CRAN without
setting a mirror Calls: <Anonymous> ... with Visible -> eval ->
install.packages -> contrib.url Execution halted
Currently, all I have in my markdown is:
8 ```{r import data}
9 install.packages("readxl")
10 library(readxl)
11 passengers <- read_excel("titanic.xlsx")
12 ```
Thank you,
Anisha
