Hi all,
Suppose that I've two data frames, a and b say, both containing a column
'id'. While data frame 'a' contains multiple rows sharing the same id,
data frame 'b' contains just one entry per id (i.e. a 1 to n
relationship). For the ease of modeling I now want to generate a new
data frame c,
I think you just need merge(), e.g.
a - data.frame(id = rep(1:3, each=3), val = rnorm(9))
b - data.frame(id = 1:3, set1 = LETTERS[1:3], set2 = 5:7)
merge(a, b, by = id)
I hope it helps.
Best,
Dimitris

Hi !
Why not constrOptim ?

Dear R users,
I'm looking for tools to perform optimization subject to constraints,
both linear and non-linear. I don't mind which
constrOptim can only handle linear inequality constraints. It cannot handle
equality (linear or nonlinear) as well as nonlinear inequality constraints.

Hi,
Look at the output of the test made in R and you can see it is a

Hey R'rs,
So im sick of dealing with ESRI products and am looking to stream line a
process i now use GIS to do using R. I have made a lot of maps using R but
have not yet seen a map that puts pie charts within the map to help
represent data like the attachment.
most likely 'combos[e,f]' is NA; take a look at your data. Also put
options(error=utils::recover)
in your program so that when the error occurs you can learn to use the
debugging mode to trace down the problem.

When putting R package names in Latex, do we use \it or \em, please?
As far as I know, the only difference between \it and \em is that \em
words are unitalicized in an italics portion of the text, which is
desirable in most cases.
However, I am not sure that italics is the most common

That's exactly what dlply does - so you should never have to do that

I'm unclear what you are saying. Are you saying that the plyr function

Note that stepwise variale selection based on AIC has all the problems
of stepwise variable selection based on P-values. AIC is just a
restatement of the P-Value.
