How to install multiple packages?

Question

How would I got about installing multiple packages in R?

I tried the following code:

install.packages(\"EIAdata\", \"gdata\", \"ggmap\", \"ggplot2\"         


        

Answer 1

load.lib<-c("EIAdata", "gdata", "ggmap","ggplot2","gridExtra","ISOweek",
"Kobe","lubridate","maps","MASS","memisc","pander","plyr","psych",
"Quandl","quantmod","reshape2","rgeos","Rgnuplot","RODBC","scales",
"sp","sqldf","stockPortfolio","stringi","stringr","XLConnect", 
"xlsReadWrite","zipcode")


install.lib<-load.lib[!load.lib %in% installed.packages()]
for(lib in install.lib) install.packages(lib,dependencies=TRUE)
sapply(load.lib,require,character=TRUE)
