get: problem with environments
Dear R users,
I am running R-2.15.1 in Linux Slackware64-14.0. Here is my minimal working example:
testfun <- function (x) {
a <- 0;
sapply(X="a", FUN=get, envir=sys.frame(which=x));
}
Inside R, that is R called from within a Linux terminal, the following code works:
testfun(x=5)
print(testfun(x=6))
But within rkward the above code fails and the following works:
testfun(x=1)

Scoping issue with irf() from {vars}
...e seems to be a problem with scoping, for irf() in vars, when
called within a function. Try the following:
-----------------------
testfun <- function(lags){
data(Canada)
var.2c <- VAR(Canada, p = lags, type = "const")
print(var.2c)
}
testfun(lags=3)
## Everything OK. Now this:
testfun2 <- function(lags){
data(Canada)
var.2c <- VAR(Canada, p = lags, type = "const")
itest <- irf(var.2c)
plot(itest)
}
testfun2(lags=3)
## I get an error message: Error in VAR(y = ysampled, p = lags, type =
"const") (from #5) :
## object 'lags' not found.

apply function across two variables by mult factors
Greetings,
I am attempting to run a function, which produces a vector and
requires two input variables, across two nested factor levels. I can
do this using by(X, list(factor1, factor2), function), however I
haven't found a simple way to extract the list output into an
organized vector form. I can do this using nested loops but it isn't
exactly an optimal approach.
Thank you
