Hello,
Is there a package or function in R that can perfom conditional regressions in
the style:
a0 = 0 Intercept is zero
0 ai 1 Parameter estimates lie between 0 and 1
sum ai = 1 Sum of the Parameter Estimates fits to 1
Many thanks for your answers!

Hi all,
I recently posted a problem concerning shaded regions with quantmod
package. More precisely,
I used the function addTA with a boolean vector: for example
addTA(vecB,col=green,border=NA,on=-1)
where vecB is the boolean vector.
In some cases, the shading result was not conform
with the
Also, shouldn't patches be encouraged?

IMHO it's really not fair to tell people that they should use
undocumented code.

Hi O,
I'll check and patch. CRAN is in desperate need of a quantmod update
- and one is coming. For now though, the change to watch for will be
on R-forge.
Thanks!,

Ok, bug found. In the R file definining the convenience functions
getEndOfBizWeek - function(date = Sys.Date()) {
stopifnot(inherits(date, Date))
bdt$getEndOfBizWeek(date)
}
getEndOfMonth - function(date = Sys.Date()) {
stopifnot(inherits(date, Date))
bdt$getEndOfMonth(date)
}
Thanks, Dirk. You're the best!

No, that is Uwe -- as the new version 0.2.1 is already on CRAN :)
Thanks again for catching this.
