我試圖讀取使用grImport庫(http://cran.r-project.org/web/packages/grImport/vignettes/import.pdf) 這裏的ps.xml文件是我的代碼:readPicture功能(grImport包)不能在Linux上工作(F22)
require("gridBase")
require("grImport")
require("plotrix")
petal <- readPicture("petal.ps.xml")
這是錯誤我收到:
Error in if (x == 0) 1 else if (x == 1) 0 else x :
missing value where TRUE/FALSE needed
這裏是我的會話信息
