Error al instalar paquetes en MAC-OS 10.13.3 R-Studio tar: Failed to set default locale

Al ejecutar la instalación de algunos paquetes, se presenta el siguiente error

install.packages(c(«ggplot2″,»lattice»,»car»,»fImport»,»tseries»,»swirl»))

tar: Failed to set default locale

Para solucionarlo capturamos la siguiente línea

system(«defaults write org.R-project.R force.LANG en_US.UTF-8»)

Ejecutamos nuevamente la siguiente línea

install.packages(c(«ggplot2″,»lattice»,»car»,»fImport»,»tseries»,»swirl»))
