Can't read xlsx file into R. Seem, Seem to have XLConnect loaded.
I have spent hours on R in Windows 7. Just installed 2 days ago so the R
package should be current.
Currently I am using the RGui (64-bit) for Windows.
I can not read an Excel file into R from my computer. Have hours on this.
Completely crazy!!
I have the XLConnect package loaded. I think it is loaded because when I

writing to .xlsx
Dear r helpers;
I'm interested in reading from and writing to large .xlsx files fairly
regularly. (Why, the naysayers may ask - and the answer is basically
colleagues and clients who prefer that format). I've tried out the
XLConnect and xlsx libraries, but the java implementation they use just
takes too much RAM for the files I'm working with.
gdata leverages perl and works really

How can I export a big data.frame to excel 2010 - file.xlsx?
Hi,
I need some help to export a data frame with 83 rows and 1411 colums. I have
used the package RODBC until now. But now, I have 1411 colums that I can't
send to the old excel. If anybody knows a package to convert my data frame
in xlsx tell me!
Thanks for help in advance!

write.xlsx error message
I think remember this error from trying to write an Excel file that already existed. If this file already exists, try to delete it and see, if this solves the issue.
Besides that you're writing that you are "Using write.xlsx to extract data from an Excel file", write.xlsx() is to write an Excel file, not to read from it. Should be read.xlsx() then iirc.

Problems with xlsx and rjava
Hi,
I keep getting the below error regarding rJava which is required by package xlsx (I have used it in the past to directly import data from Excel 2010).
I was on R version 2.15.0 when I was getting this error this morning. So I upgraded to 2.15.1 but still the same problem. I tried unstalling and reinstalling xlsx and even rJava directly from the source as indicated here:

I would like to save my data as a xlsx file. But at first
I need to split it and then save each series into a Excel
column. Please take a look at the following code:

"XLConnect" packages; Excel dates read incorrectly
Hi,
I tried to read xlsx files by "XLConnect" packages, but the dates are
one day earlier than it is supposed to be. I moved from California to
Taiwan (Eastern Asia), and it worked well in California, but not in Taiwan.
Even if I adjust my Mac time to California time zone, it gives the wrong
dates. I don't know which part of the setting (in RStudio or in my Mac?) I
should adjust.
