Edit Question
Title
Body
I have some code that I run that includes this part: if (!require("yaml")) { install.packages("yaml") library("yaml") } When I run in it rstudio, everything runs seamlessly and there are no bugs. However, when I try running my code on the command line, I get this error: $ Rscript.exe file.R Loading required package: yaml Installing package(s) into ‘/usr/lib/R/site-library’ (as ‘lib’ is unspecified) Error in contrib.url(repos, type) : trying to use CRAN without setting a mirror Calls: install.packages -> grep -> contrib.url In addition: Warning message: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, : there is no package called ‘yaml’ Execution halted
