问题
I'm a beginner with R. I want to launch R scripts at specific moments, managing this with Linux's cron and launching the scripts as Rscript name_of_the_script.
I have installed tidyverse in Rstudio, with install.packages("tidyverse"). Ok, but I guess that installation is specific to the Rstudio environment. When working in a script (not using Rstudio), and launching that script with Rscript, the library tidyverse is not installed. Even worse, I couldn't install it in the script with install.packages("tidyverse").
What do you suggest? Thanks.
回答1:
The library is, in fact, probably installed. It is difficult to be sure of what is the problem without more details, but I would guess that you did not load your library in your script. Try to add the following at the beginning on the first line of your script
library(tidyverse)

The solution is you simply use require() to load your package without worrying about the path.
require(dplyr)
