使用包openxlsx保存xlsx工作簿时出错

Question

我正在浏览R Statistics中的openxlsx包中的插图示例,但我无法保存工作簿,我无法弄清楚原因.下面的代码是插图中的一个修改示例,只是为了简单起见.

setwd("c:/users/kenneth/documents/r/2014-04-29_openxlsx")
require(openxlsx)
require(ggplot2)
wb <- createWorkbook()
addWorksheet(wb, sheetName = "Motor Trend Car Road Tests", gridLines = FALSE)
addWorksheet(wb, sheetName = "Iris")
addWorksheet(wb, sheetName = "Conditional Formatting")
saveWorkbook(wb=wb, file="basics.xlsx", overwrite=TRUE) ## save to working directory

我得到的错误信息是:

Warning message:
running command '"zip" -r1 "c:/users/kenneth/documents/r/2014-04-29_openxlsx/basics.xlsx" "[Content_Types].xml" "_rels" "docProps" "docProps/app.xml" "docProps/core.xml" "xl" "xl/_rels" "xl/_rels/workbook.xml.rels" "xl/charts" "xl/drawings" "xl/drawings/_rels" "xl/printerSettings" "xl/printerSettings/printerSettings1.bin" "xl/printerSettings/printerSettings2.bin" "xl/printerSettings/printerSettings3.bin" "xl/styles.xml" "xl/tables" "xl/tables/_rels" "xl/theme" "xl/theme/theme1.xml" "xl/workbook.xml" "xl/worksheets" "xl/worksheets/_rels" "xl/worksheets/_rels/sheet1.xml.rels" "xl/worksheets/_rels/sheet2.xml.rels" "xl/worksheets/_rels/sheet3.xml.rels" "xl/worksheets/sheet1.xml" "xl/worksheets/sheet2.xml" "xl/worksheets/sheet3.xml" ' had status 127

我已经更新到最新版本的R,devtools和Rtools.

Answer 1

我认为这里的问题是R找不到Rtools附带的zip应用程序.

您可以使用该命令检查Rtools bin目录是否在R的系统PATH中

shell("PATH")

输出应该看起来像这样(取决于你安装Rtools的位置):

PATH=c:\Rtools\bin;c:\Rtools\gcc-4.6.3\bin;C:\Windows\system32;C:\... etc

如果Rtools\bin目录没有出现在字符串中的任何位置,请将其添加进去.

如果这不起作用给我发电子邮件,我会帮你进一步(电子邮件在插图中)
