Automatically - "Convert numbers stored as text to numbers"
让我们考虑这个小例子：
df1<- data.frame(A=c(1,NA,"pvalue",0.0003),B=c(0.5,7,"I destroy","numbers all day"),stringsAsFactors = T)
写入文件：
openxlsx::write.xlsx(df1,"Test.xlsx")
在我生成的 excel 文件中，1 和 7 是文本单元格。 Excel 具有 "intuition" 它们是作为文本存储的数字。我可以手动转换它们。
如何将这些 "flagged" 值自动转换为 R 内部的数字？
在 "What I want" 中，我手动将文本转换为数字。它是 "What I get" 部分（红色箭头）中 "green triangle" 后面的一个选项。
@Roland 的评论：重新排列为列表不起作用。
df1<- as.data.frame(cbind(A=list(1,NA_real_,"pvalue",0.0003),B=list(0.5,7,"I destroy","numbers all day")))
openxlsx::write.xlsx(df1,"Test2.xlsx")
我按照@Roland 和@phiver 的建议写了一小段代码。它以整洁的data.frame开头（保留每个单元格的数据类型）并逐个保存值：
library(openxlsx)
df1<- as.data.frame(cbind(A=list(1,NA_real_,"pvalue",0.0003),B=list(0.5,7,"I destroy","numbers all day")))
wb <- createWorkbook()
sheet.name <- 'test'
addWorksheet(wb, sheet.name)
for(i in seq_along(df1)){
writeData(wb, sheet = sheet.name, names(df1)[i], startCol = i, startRow = 1)
icol <- df1[[i]]
for(j in seq_along(icol)){
x <- icol[[j]]
writeData(wb, sheet = sheet.name, x, startCol = i, startRow = j + 1)
}
}
saveWorkbook(wb, file = "Test.xlsx")
希望这对您的数据有用。

示例数据：
df1 <- mtcars
df1[1,3]<-"ID =====>"
df1[1,4]<-"00000123"
df1[3,7]<-NA
df1[2,6]<-"stringi"

通话：
writeXlsxWithTypes(df1, "test_normal3.xlsx" , rowNames = TRUE, borders = "surrounding")
writeXlsxWithTypes(ldf, "test_list3.xlsx", rowNames = TRUE, borders = "surrounding")
为了防止它对其他人有帮助，我导入了一个 excel 文档，对数据框进行了一系列操作，然后将其写为一个新的 excel 文档。我不想把从 char 到 numeric 的转换放在数据框中，因为它会弄乱我现有的代码，所以我把它放在 writeData 位中。
