如何使用 openxlsx 向 excel 工作簿添加多条评论？

Question

createComment openxlsx function 描述指出注释可以是“字符向量”，因此适用于多个单元格。

但是，添加评论似乎仅限于一个单元格。

有没有办法使用字符向量向一系列单元格添加多个注释？

我错过了什么还是这是一个增强请求？

此 MWE 失败并显示以下消息：“comment_list[[i]]$style[[j]] 中的错误：下标超出范围”

library(openxlsx)

x <- as.data.frame(matrix(1:12, nrow = 3))
names(x) <- letters[1:4]

comment_vector <- paste("Comment", 1:4)

wb <- createWorkbook()
addWorksheet(wb, 1)

header_comments <- createComment(comment = comment_vector)
writeComment(wb, 1, col = 1:4, row = 1, comment = header_comments)

writeData(wb, sheet = 1, startRow = 1, x)

saveWorkbook(wb, "muliple_comments.xlsx", overwrite = TRUE)

这行得通，但必须有更好的方法......

header1_comment <- createComment(comment = comment_vector[1])
writeComment(wb, 1, col = 1, row = 1, comment = header1_comment)

header2_comment <- createComment(comment = comment_vector[2])
writeComment(wb, 1, col = 2, row = 1, comment = header2_comment)

header3_comment <- createComment(comment = comment_vector[3])
writeComment(wb, 1, col = 3, row = 1, comment = header3_comment)

header4_comment <- createComment(comment = comment_vector[4])
writeComment(wb, 1, col = 4, row = 1, comment = header4_comment)

writeData(wb, sheet = 1, startRow = 1, x)

saveWorkbook(wb, "05_muliple_comments.xlsx", overwrite = TRUE)

我不认为createComment允许在多个单元格中进行评论，字符向量组件可以按照?createComment中的示例应用多个 styles 。

解决这个问题的最简单方法可能是使用lapply或for循环。

lapply(1:4, FUN = function(x) writeComment(wb, 1, col = x, row = 1, comment = createComment(comment = comment_vector[x])))

因此，在您提供的示例中，它将类似于：

library(openxlsx)

x <- as.data.frame(matrix(1:12, nrow = 3))
names(x) <- letters[1:4]
comment_vector <- paste("Comment", 1:4)

wb <- createWorkbook()
addWorksheet(wb, 1)

# Add multiple comments
lapply(1:4, FUN = function(x) writeComment(wb, 1, col = x, row = 1, comment = createComment(comment = comment_vector[x])))

writeData(wb, sheet = 1, startRow = 1, x)
saveWorkbook(wb, "muliple_comments.xlsx", overwrite = TRUE)
