[R] Translating actxserver server commands to rcom

[W Eryk Wolski]

Dear R and R com user....

I have the following matlab which acesses a com server, code which I
am trying to translate to R using the Rcom package:


clear all;
clear analysis;
analysis = actxserver('EDAL.MSAnalysis');
analysis.Open('E:\work\ChromPeakFinderdata\DatafromKlaus\E112L-cad13-PI-24h_pos_1-C,3_01_2562.d');
specCol = analysis.MSSpectrumCollection;
count = specCol.get('Count');


This is how far I got...

rm(analysis)
analysis <- comCreateObject("EDAL.MSAnalysis")
comGetObjectInfo(analysis)
comInvoke(analysis,"open","E:\work\ChromPeakFinderdata\DatafromKlaus\E112L-cad13-PI-24h_pos_1-C,3_01_2562.d")
specCol <- analysis$"MSSpectrumCollection"
> specCol
function (...)
comInvoke(handle, ..FUN, ...)
<environment: 0x022a4734>
> comInvoke(specCol,"get","Count")
NULL


Seems to be the wrong track ... What would be the equivalent of
analysis.Open('E:\work\ChromPeakFinderdata\DatafromKlaus\E112L-cad13-PI-24h_pos_1-C,3_01_2562.d');
specCol = analysis.MSSpectrumCollection;
or  of count = specCol.get('Count');
in Rcom?


Help is highly appreciated...

best wishes

Eryk
