Hello all:
I have a question regarding the fitted.values returned from the
zeroinfl() function. The values seem to be nearly identical to those
fitted.values returned by the ordinary glm(). Why is this, shouldn't
they be more "zero-inflated"?
I construct a zero-inflated series of counts, calle
If the problem is that you have a vector of dates, a vector of times
and a vector of data and you want to create a data frame with one
POSIXct column and one column of data then try this:

tt <- c("01:01:00", "23:01:12")

Hi Guys,
I'm cooking up my time series code. I want a data frame with first column as

I hit on this the problem of how to create an array/list/vector of POSIXlt

it seems there's a bug in geom_ribbon() when using it in a log-scaled plot:

p<-ggplot()
p<-p+geom_ribbon(data=d,aes(x=d[["x"]],min=d[["y1"]],max=d[["y2"]]))
p<-p+geom_line(data=d,aes(x=d[["x"]],y=d[["y1"]]),colour="blue")
Thanks for those detailed explanation and the time taken to write them.
