当我的照片被创建时，它们看起来像那样：

此外，我收到错误：

  

[.data.frame（dataSelection，i）中的错误：选择了未定义的列

有什么建议我做错了吗？对于输出创建，for函数是否“快”？

感谢您的回复！

Answer 1

这应该做你想要的：

names <- LETTERS[1:26]
for(i in 1:dim(dataSelection)[2]){
  mypath <- file.path("C:","Users","Desktop","PlotOutput",paste("myplot_", names[i], ".png", sep = ""))
  png(file=mypath)
  mytitle = paste("my title is", names[i])
  plot(dataSelection[,i], main = mytitle)
  dev.off()
}

至少它对我有用。我更改了您的索引（请参阅我的评论），最后[i]似乎也可以正常工作，但请将其设为[,i]以获取可读性/样式/和所有内容。

最后，请在下次发布MINIMAL示例。
