Hi KZ,
I don't think that I can answer what I think is the precise question - how
to run the R file from VBA but without using RExcel.
However with RExcel installed, I have found it very straightforward to run R
code from within VBA (thanks Erich Neuwirth - RExcel is great). The VBA
code is:
I have an R file R_test.R saved in C:\R_test folder. The R_test.R looks like
this:
setwd(C:/R_test)
rnorm(100)
write(rnorm(100),data.txt)
q(save=no, runLast = F)
Next I would like use an Excel VBA/macro Shell() function to call R and
execute R_test.R file. The syntax is
Hello all ,
Does any one know how to use the neural networks package for time series
prediction ? Have you a similar example in R language ?
thanks in advance

This seems pretty basic, but I can't get any data to work except for the
documented examples. When the goal is to get to SpatialPixels, here is what

Say I have a csv file, each row contains several fields, one of them

In history data, I have all the fields including the result of whether
it is success. In future data, I only have fields without the result.

Dear R-helpers:
I have a question related to using do.call to call cbind and get.
#the following works
vec1 - c(1,2)
vec2 - c(3,4)
ColNameVec - c('vec1','vec2')
mat - do.call(cbind,lapply(ColNameVec,get))
mat
#put code above into a function then it does not work
#before doing so, first remove
Use lapply(ColNameVec, get, environment())
so that it gets the objects from the current
environment. See: ?get ?environment

Dear kxk,
Here are a couple of options:
# Option 1 -- sapply
mydata - sapply(1970:2005, function(i){
mydata - read.table(file = paste(edge_, i, .csv,
sep=), header=TRUE)
# more code goes here

Not really obfuscation, there are legitimate reasons to want this sort of
