如何在R的outlook体中显示excel工作表

Question

我可以通过RDCOMClinet包将excel文件附加到outlook中。 但是如何通过R在邮件正文中显示excel工作表内容？ 假设表格和图表包含在工作表中。

library(RDCOMClient)
## init com api
OutApp <- COMCreate("Outlook.Application")
## create an email
outMail = OutApp$CreateItem(0)

## configure  email parameter
outMail[["To"]] = "name@email.com"
outMail[["subject"]] = paste0("Report ", Sys.Date() - 1)

# attach a file via its directory
dirs <- dir(getwd(), full.names = TRUE)
outMail[["Attachments"]]$Add(dirs)

# insert an excel worksheet from attachment or local drive
outMail[["HTMLBody"]] = ?  

Answer 1

对于表格部分，您可以这样做

library(RDCOMClient)
library(openxlsx)
library(xtable)

OutApp <- COMCreate("Outlook.Application")
outMail = OutApp$CreateItem(0)
outMail[["To"]] = "ex@example.com"
outMail[["subject"]] = paste0("Report ", Sys.Date() - 1)

wb <- createWorkbook()
addWorksheet(wb, "S1")
writeDataTable(wb, "S1", x = head(iris))
saveWorkbook(wb, tf <- tempfile(fileext = "xlsx"))
df <- read.xlsx(tf)
df_html <- print(xtable(df), type="html", print.results=FALSE)

outMail[["Attachments"]]$Add(tf)
outMail[["HTMLBody"]] = sprintf('
Hello world, here is the table:
%s
Merry Christmas & a happy New Year!
', df_html) # add your html message content here
outMail$Send()

我不知道图表部分的选项。也许在Outlook电子邮件中嵌入Excel图表并检查生成的HTML？
