[R] using portfolioMarkowitz
Hi, I'm pretty new to R and I'm trying to use the functions portfolioMarkowitz and portfolioMonteCarlo. I think that its in the package fPortfolio but it doesn't seem to work with I install the package and import the library. I think this may be because It only existed in an old version of the package. I see some old versions available on cran but I am a windows user and can't figure out how to install them and have them work. Any suggestions would be much appreciated.

[R] RExcel rcom Server Loading The Wrong Version of R
Hi,
I'm pretty new to R and VERY new to RExcel. I've just finished setting
it up and I'm having some problems. My first Issue is that if I attempt
to use a function like RApply("sum", A1:A4) from within excel it gives
me an error saying "There seems to be no R process connected to the
server" I can then see an R Console open up and I get a message saying R
Server not available. The weird thing is that the r console that opens
up is R 2.7.1 and I did all of the installation of rcom and rexcel on R
2.7.2. I've tried uninstalling 2.7.1 but I get an error saying that it
can not find the unistall file. Is it possilbe that When I installed R
2.7.2 I did something wrong that is causing this problem? If I start
running R2.7.2 and then open excel and try using Rapply it works
perfectly but I don't want to have to manually start R every time.
The second question I have is in regards to using RApply to call R
functions which rely on functions in other libraries. I've resorted to
creating a function in my excel file which looks something like...
Cell Function
A1 getLibs<-function(){
A2 library(MBESS)
A3 library(corpcor)
A4 }
B1 =rproc(A1:A4)
C1 =rApply("getLibs")
Is their a better way to go about accomplishing this? Thanks in advance
for any insights you have either of these quesitons
Ben
