将minitab文件导入R时出错

Question

我在R中使用外部程序包来导入MTP文件，但它仅显示文件读取错误。我已经设置了默认目录，但是它不起作用。如果能得到帮助，我将不胜感激。预先谢谢你。

library(foreign)

d44<-read.mtp("PERAGGR.MTP")

Here is the file that I was using

Answer 1

read.mtp函数非常古老。由于该文件实际上是ASCII文件，因此只需使用`readLines：

进行读取

d44<-readLines("~/Downloads/PERAGGR.MTP")
head(d44)
