R闪亮的selectInput带\\ r \\ n

Question

我正在将数据从excel电子表格上传到Shiny，该公司的名字包括\\ r \\ n，而selectInput不允许我选择它们。 R中有解决方法吗？

任何建议将不胜感激！

library(shiny)

D = matrix(runif(400), nrow = 20)

colnames(D) = c("PROTECT",

}

shinyApp(ui = ui, server = server)

\\r\\n是Windows的换行符，可能是因为原始数据在Excel中具有包含多行的单元格。

您可以使用以下方法将它们转换为空格：

colnames(D) <- gsub("\r\n"," ", colnames(D))
