How could I restrict and reordered data.frames?
Dear Everyone,
I 've just begun to use the library ncdf and I would like to compare meteorological observational data with forecast data, so to make verification. The netcdf files I'm using contain data of many different parameters in many different stations. I could read easily that I needed, but naturally I do not need the data of all the stations. On the other hand, the order of

RoR data models ( extreme newbie question)
Sorry for asking this but I am keen to get on and build an app based on
RoR and have had a look around at FAQa and the like with no immediate
sucess.
What I am looking for is an explainantion of the rules/requirements for
table/index/coulumn names with RoR. RoR appears to have a set of
expected naming conventions which it would appear you can over ride but
it would seems a hell of a lot

2 ecdf from different set of data
Hi r-users,
I have 2 sets of data and I would like to superimpose this cumulative density in one graph.
I know how to put the 2 graphs in one same graph but my problem is the data are different.

Can boot return matrix?
...s. Any idea how to set it up?
Also a note, the examples at the end of the boot.ci documentation, for the
city and gravity data set I get error messages for boot.ci() call. Did
anyone else noticed that? E.g.
> boot.ci(grav1.boot, type=c("stud","norm"))

Why using hist when setting the parameter probability=TRUE does not create probability plot?
Hi All,
When carrying out hist(samples,breaks=50,probability=TRUE), the column
values are considerably greater than 1, which seams very unreasonable. The
plot is attached.
I think the column value of the hist plot should correspond to
x$counts/sum(x$counts)
(x=hist(samples,breaks=50,probability=TRUE)). The size of data is a
little bit larger, causing failure of uploading. If you need the
