在线阅读 xlsx - sheet in R

Question

我无法阅读此 xlsx 文件并使用 sheet=2 ("Data") “http://www3.weforum.org/docs/gcr/2015-2016/GCI_Dataset_2006-2015.xlsx”

我做了什么：

library(readxl)
library(XLConnect)
library("openxlsx")

temp = tempfile(fileext = ".xlsx")
dataURL <- "http://www3.weforum.org/docs/gcr/2015-2016/GCI_Dataset_2006-2015.xlsx"
download.file(dataURL, destfile=temp, mode='wb')
file<- read.xlsx(temp, sheet= 2)

我得到以下信息：

Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl,  :  java.lang.OutOfMemoryError: GC overhead limit exceeded

有人可以帮忙吗？谢谢 :)

Answer 1

我对这个特定文件使用 readxl 似乎没有问题。对于同一个包，我确实遇到了由我无法控制的其他系统创建的特定电子表格的问题（开发人员知道这一点）。

如果我运行这个：

temp = tempfile(fileext = ".xlsx")
dataURL <- "http://www3.weforum.org/docs/gcr/2015-2016/GCI_Dataset_2006-2015.xlsx"
download.file(dataURL, destfile=temp, mode='wb')

test <- readxl::read_excel(temp, sheet =2)
head(test)

我得到以下输出：
