RCOM Package
Hi list,
I just installed the rcom package and tried to read/give out some values
from/to Excel. Altogether it works great... but nevertheless I don't know
how the syntax works or in other words: "Which command needs which
parameters?"
Is there somwhere a manual about this package with good examples? I've read
the Package description... but there are not really good

UpdateLinks = FALSE
Hi,
I'm reading 100s of excel files and many of them contain links to external files (I hate that, but that aside). Every time such a file is opened, a menu pops up asking if I want to update the links. I never want to update the links. I used the macro recorder to see what code would be needed to suppress that message, but to no avail (I tried more variations, but one attempt is shown

Dear Sir,
rcom is a great package of R. Yet it seems that there is some problem of
Chinese character supporting.

Any suggestion would be appreciated.
Thanks.

clear console
hi,
I use R - 2.15(32bit), and want to make a code to clear a console.
Actually, I used to run following code to do that but after update the
version of R from 2.14 to 2.15, it doesn't work.
cls <- function (t) {
require(RDCOMClient)
wsh <- COMCreate("Wscript.Shell")
wsh$SendKeys("\f")
invisible(wsh)
}
cls()

clear screen?
I?ve been using this routine for several years. I?m sorry, I don?t remember
where I got it. It works as it should, viz. it blanks the R console. But
it requires package rcom and now that requires rscproxy.
cls <-
function ()
{
require(rcom)
wsh <- comCreateObject("Wscript.Shell")
comInvoke(wsh, "SendKeys", "\f")
invisible(wsh)
}

control L to clear the Rgui screen in Windows
Greetings R-ians:
Searching the Searchable Mail Archives I discovered that ctrl L will clear
the Rgui screen, which is what I'd like to do from a print (or some similar)
statement.
Is there a mechanism to use the ctrl L clear-screen sequence in a script, or
print statement?
Thanks for your counsel.

Populating values in a PowerPoint table
Dear R-help,
I managed (thanks to the R2PPT package) to create a PowerPoint
presentation and create a table in it but for the life of me I can't
find a way to populate the table with values and text. I'm aware of
the function 'PPT.AddDataFrame' which creates an Excel object from a
data frame, but the excel object is not nearly as nice looking and
easy to manipulate (and apply

xlsReadWrite Pro and embedding objects and files in Excel worksheets
Hans-Peter and other R developers,
How are you? Have you made any progess with embedding Url's in Excel?
Well, I have been busy thinking of more things for you to do;)
My colleagues in the lab are not R literate, and some are barely
computer literate, so I give them everything in Excel workbooks. I have
gradually evolved a system such that these workbooks have become

lm with an arbitrary number of terms
Hello folks,
Any ideas how to do this?
data.frame is a data frame with column names "x1",...,"xn"
y is a response variable of length dim(data.frame)[1]
I want to write a function
function(y, data.frame){
lm(y~x1+...+xn)
}
This would be easy if n was always the same.
If n is arbitrary how could I feed the x1+...+xn terms into lm(response~terms)?
Thanks
Richard

[OT] VBA to save excel as csv
Hi all,
This is a little off-topic, but it is on the general topic of getting
data in R. I'm looking for a excel macro / vba script that will
export all spreadsheets in a directory (with one file per tab) into
csv. Does anyone have anything like this?
Thanks,
