## i have one question anouth this package.. library(datasets) eurodist ## if i type this i get max distance between european cities > max(eurodist) [1] 4532 ## but i would like get something like this: 4532 Gilbratar - Anthens ## and another one.. ## if a live in barcelona and i would like travel in all cities ## how can i get sum of all distance to other cities....

If I perform PCA on the 'eurodist' data, should I get an accurate geographic layout of the cities with biplot? (barring inversions, i.e. their is no way to define north.. but you get the idea...) I have a complex distance matrix, and I am thinking about how to cluster it and how to visualize the quality of the resulting clust...

The eurodist dataset (my favorite for mds) is malformed. Instead of a standard distance matrix, it's a data frame. The rownames have gotten 'bumped' to a new anonymous dimension "X". It's possible to fix the data, but it messes up a lot of example code out there. X Athen...

...ant hang during cmdscale of the mva library. Some data never cause a problem, other data always do, abut I can't track down the difference in the structure of the data. Sometimes the function will work for `difficult' data after it has been run in the same session for `behaved' data (eurodist always works)! Here is a typical session: $ R > library(mva) > x <- read.table("test.dat",row.names=1) > x V2 V3 A 1 2 B 2 4 C 5 7 D 1 1 > dist(x) A B C B 2.236068 C 6.403124 4.242641 D 1.000000 3.162278 7.211103 > cmdscale(dis...

...order b,a. Subjects are not perfectly consistent and so will not give exactly the same answer twice. However it is reasonable to take the average of a,b and b,a. I would like to do cmdscale or isoMDS on the data. As I understand it, these take the data as a lower triangle. At least that is how the eurodist example for cmdscale went. So in my case I need c b 1.20 a 0.95 2.10 a b c Starting from the dataframe at the top of this posting, how do I get a lower triangular matrix in this form, with the labels a, b, c (just like eurodist)? Thanks very much for any help. Bill

Can some tolerant person let me know the way to enter this into a distance or symmetric matrix structure in R? Also, in the 'eurodist' example given with cmdscale.html the plot gives the point labels, but no symbol showing the location of the point. Is it possible to specify a plotting symbol as well as the label? Regards, Murray Jorgensen -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r...
