在Rstudio中读取xlsx文件

Question

I am taking the R programming class from Cousera, and while I was practising how to read in xlsx files using read.xlsx, I encountered the following error message:

dat<- read.xlsx(file="./data/nga.xlsx", sheetIndex=1)

Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, : java.util.zip.ZipException: oversubscribed literal/length tree

R version 3.2.1, R studio version 3.2.1, platform windows7 64bit. Can anyone give a hint what this message means and how to work around it?

Thanks, Gezimao

Answer 1

您下载的文件已损坏，因此请使用参数'mode =“wb”'再次下载该文件。

Answer 2

试试这个包https://github.com/hadley/readxl

read_excel("my-new-spreadsheet.xlsx")

Answer 3

Download and install this java: http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html

then run your code and it should work. If it does check best answer :)

Answer 4

I had the same problem. The .xlsx file may be 'read only'. Try 'Save As' to a new file from Excel and try read.xlsx again.
