How to read multiple packages using a for loop in R?

Question

This is my code:

library(gcookbook)
library(ggplot2)

I'd like to achieve something like the following:

packages <- c("gcookbook","ggplot2") 
for (i in length(packages)) { 
  library(packages[i]) 
} 

How can I do this? Thanks in advance!

Answer 1

Instead of using a loop you can use the lapply function like this:

packages <- c("gcookbook", "ggplot2")
lapply(packages, library, character.only = TRUE)
