In a loop I would do this: for (i in 1:length(a)) a[i] <- scalar * a[i] [[alternative HTML version deleted]]

I am trying to triangulate a point set as follows: > head(cbind(x,y)) x y [1,] -78.1444 -60.4424 [2,] -78.1444 -58.4424 [3,] -78.1444 -56.4424 [4,] -78.1444 -54.4424 [5,] -76.1444 -60.4424 [6,] -76.1444 -58.4424 > length(x) [1] 5000 > tri <- tri.mesh(x, y) Fehler in tri.mesh(x, y) : error in trmesh > tri <- tri.mesh(x, y, "remove") Fehler in tri.mesh(x, y,

I am trying to get contents of a REST response: getURL("http://localhost/myweb-app/rest-ws") This is a web application (myweb-app) which is providing a REST web service (rest-ws)...
