# R安裝套件時最常用的方法之一是選取 RGui 介面 :
# 程式套件 \ 安裝程式套件 \ 選取 mirror site \ 選取 套件名稱
# 以下介紹採用指令方式直接下載套件
# 方法1, 直接指定套件名稱, 左右加上雙引號, 此方法仍須選取 mirror site.
install.packages("e1017")
# 方法2, 直接指定套件名稱並且以 repos 參數指定 mirror site.
install.packages("e1071", repos=
http://cran.cs.pu.edu.tw/
)
# end

上面網址應加上雙引號才正確:
install.packages("e1071", repos="
http://cran.cs.pu.edu
.tw/
")
謝謝 Vince 提醒
