在R中读取大xslx文件

Question

I am trying to read a big excel file with almost 30000 rows and 6000 columns.

I have tested XLConnect and XLSX package, but I get java I/O error:

java.io.IOException: ZIP entry size is too large

How can I read such a big xlsx file in r?

Answer 1

You can increase the memory available to java in the options (in R). Typically like this:

options(java.parameters = "-Xmx1000m")
data <- read.xlsx(filepath)
