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
descriptions/examples.
I know the following parameters/commands:
#Connect to the active Workbook
excel <- comGetObject("Excel.Application")
#Set the active sheet
sheet <- comGetProperty(excel,"ActiveSheet")
#Set a specific sheet
sheet <- comGetProperty(excel,"Worksheets","WorksheetXY")
#Create a new Worksheet
comInvoke(comGetProperty(excel,"Worksheets"),"Add")
#Define a range in a defined sheet
range1 <- comGetProperty(sheet,"Range","A1","A20")
#Read out this range from Excel
val1 <- as.double(comGetProperty(range1,"Value"))
#Give back the results to Excel
comSetProperty(range1,"Value",val1)
Some of my questions are:
- How can I rename a worksheet?
- How can I define the name of a new worksheet?
- How can I delete a worksheet?
- How can I connect to a specific Workbook, if more than one is opened?
- ...
Can someone help me?
Thanks,
Thomas
