Why does the graph converge?
I have a set of functions:
Probability <- function(N, f, w, b, l, n, q) {
#N is the number of lymph nodes
#f is the fraction of Dendritic cells (in the correct node) that have the
antigen
#w is time in terms of hours
#b is the starting position (somewhere in the node or somewhere in the gap
between nodes. It is a number between 1 and (x+t))
#q is the length of the time step
#l is the LN

Using R.dll in .NET IPC
Hi - I wrapped R.dll up using somebody code online (see below). I am comparing R on .NET IPC with R(D)COM.
I got it all working. Except, I realize that in my client code of the IPC remoting, if I call 'plot' function in R via EvaluateNoReturn, I don't seem to see any results on the R plot window (although the window pops up). Is there anything to do with the code of R.dll wrapper

C++ & R: Displaying a lattice graphic using D Com
Dear list members,
When I modify the MFC sample (using the statconnector graphics device) to
show a lattice graph in the Active X control (actually the wireframe from

runs without generating any errors, but the data-driven part of the plot
does not display. The bounding box is displayed, but not the axes or data

odbcConnectAccess function
HI:
Is it possible to use the RODBC package within MS Access. I have been using from R but was just wondering if it could be used along with R(D)COM. Something like this:

Dim myApp As StatConnector
Set myApp = New StatConnector
myApp.GetErrorText
myApp.Init "R"
myApp.EvaluateNoReturn "library(RODBC)"

workaround a performance problem of the StatConnector.
It's almost work but ... I have strange memory exception when I call the

Line splitting in system() (PR#6624)
According to the manual, system() splits output lines into
