Hi Bert,
Good reference and David Urbina's example showed that a simple swap
was position dependent. The reason I pursued this is that it seems
more efficient to sequentially apply the precedence rules to the
arbitrarily sorted elements of the vector than to go through the
directed graph approach.
Thanks Bert. Excellent reference, I learned a lot from it!

This is called topological sorting in some circles. The function below
will give you one ordering that is consistent with the contraints but not
all possible orderings. I couldn't find such a function in core R so I
wrote one a while back based on Kahn's algorithm, as described in Wikipedia.

It seems that on my machine "sort" (and related functions like "order")

I suspect it is a problem related to locales: R and the base Ubuntu might
be using different locales, hence the source of the different sorting.

If you already have the order stored in a list or so:

c("P2","P3","P1"),c("S2","S1","S3"))

factor(dat1[,i],levels=lst1[[i]]))
Hi,
Not sure whether this helps:
dat1 <- as.data.frame(mat,stringsAsFactors=FALSE)
dat1$c4 <- factor(dat1$c4,levels=c("OF","ON"))
dat1$c1 <- factor(dat1$c1,levels=c("US","UK","WW","BO","BR","CA"))

I was wondering if one can have the coefficients of VAR model sorted
according to variable names rather than lags. If you notice below, the
output is sorted according to lags.

after all, brute force seems the way to go.
I will use a simplified example to illustrate what I want (dump of dat4 is

suppose dat4:

Nice suggestion for the extra "Time" column
y possible
combination of shuffling within certain limits (eg max 10% or so), calculate r2
for each combination and maximize?
Seems so brute force and low elegant?

Hi,
I'm a database admin for a database which manage chromatographic results of
products during stability studies.
I use R for the reporting of the results in MS Word through R2wd.
But now I think I need your help:
suppose we have the following data frame:
ID rrt Mnd Result
1 0.45 0
Spring 0.1927715

Hello all,
I cannot seem to figure out this seemingly simple procedure.
I want to sort a data frame by a specified character vector.
So for :
df.. <- data.frame(Season=rep(c("Summer","Fall","Winter","Spring"),4),Obs=
runif(length(rep(c("Summer","Fall","Winter","Spring"),4
I want to so
Please show the data set...

Thanks a lot.
But I also want to attach row names (if available) associated with each column.
In that case does your second code works in the same way?
thanks
