[R] loading packages in a function

[Arnaud Gaboury]

TY for your answer, but here what i did :

#load needed lybrary
suppressPackageStartupMessages(library(plyr))
suppressPackageStartupMessages(library(car))
library(plyr)
library(car)


But I still get :

Loading required package: MASS
Loading required package: nnet

Perhaps the longest function in base R I know of:

suppressPackageStartupMessages

e.g.,

suppressPackageStartupMessages(library(zoo))
