data <- read.delim("F-F_Research_Data_5_Factors_2x3_Wireless_CSV.TXT", sep = "|")

Answer 1

我能够通过以下方式读取数据集：

download(url="http://mba.tuck.dartmouth.edu/pages/faculty/ken.french/ftp/F-F_Research_Data_5_Factors_2x3_daily_CSV.zip", dest="<directory and filename>/F-F_Research_Data_5_Factors_2x3_daily_CSV.zip", mode="wb") 
unzip ("<directory and filename>/F-F_Research_Data_5_Factors_2x3_daily_CSV.zip", exdir = "Yourfilename")

x <- read_csv("<directory and filename>/F-F_Research_Data_5_Factors_2x3_daily.CSV", skip = 3)

x %>%
  mutate_at(vars(-X1), funs(./100))

将zip文件加载到R中
