...ANN") in the optim function. So I would like to have a vector with c("Nelder-Mead", "BFGS", "CG", "L-BFGS-B", "SANN") Or for instance the 'method' in the dist function can be supplied with euclidian,maximum,manhatten, canberra,binary,minkowski. Is there someway to extract this so I would have a vector with c("euclidian","maximum","manhatten", "canberra","binary","minkowski"). Thanks

Is there a function that calculate the mahalanobis distance in R . The dist function calculates "euclidean"', '"maximum"', '"manhattan"', '"canberra"', '"binary"' or '"minkowski"'. Thanks ../Murli

Personally, I find that indenting config files by 3 spaces has a lot of advantages to indenting them by 4 spaces although conventional wisdom might suggest otherwise. Who's with me on this?

...This works fine. Now I would like to use other dissimilarity measures as can be found in the function dist (STATS) or vegdist (VEGAN). De'Ath notes that gdist should be interchangeable with dist - but I receive following error message: > fit21 <- mvpart(dist (ba12[,18:29], meth="minkowski", diag=T, upper=T p=2) ~ beers + slope_dem + elev_dem+ plc_dem + pr_curv+ curv+max_depth+doc_rocks+ abandon+land_use+ca_old, data=ba12, xv="p") Error in model.frame(formula, rownames, variables, varnames, extras, extranames, : Variable lengths differ When comput...

Estimados compañeros estoy con un trabajo sobre redes pathfinder y quería saber si conocéis alguna librería o función para dada la matriz de proximidades sacar la matriz de la red pathfinder. Un cordial saludo y un mejor año 2013.

Hi All, Just want to make sure, in function "bclust", do the following argument only have one option? argument "dist.method" has one option "Euclidian"; argument "hclust.method" has one option "average"; argument "base.method" has one option "kmeans". Thank you! [[alternative HTML version deleted]]

the first line of dist() says if (!is.na(pmatch(method, "euclidian"))) shouldn't that be "euclidean" ? --------------------- R version 2.5.1 (2007-06-27) i486-pc-linux-gnu locale:

I could not figure out what was the default when I ran hclust() without specifying the method. For example: I just have a code like: hclust(dist(data)) Any input would be appreciated:) [[alternative HTML version deleted]]

I have spatial data on a sphere (the Earth) for which I would like to run an gls model assuming that the errors are autcorrelated, i.e. including a corSpatial correlation in the model specification. In this case the distance metric should be calculated on the sphere, therefore metric = "euclidean" in (for example) corSpher would be incorrect. I would be grateful for help on how to
