Hi, I dont know if this a coding rule or a program bug. When I write this function below it work: a <- c(1,2) for(i in a){ print(i) } [1] 1 [1] 2 But if I write this function with line space it dont work. a <- c(1,2) for(i in a){ print(i) } Error: unexpected '}' in "}" I remember that in early R version this limitation dont exist. This is a bus, a rule or a

Hi, I try to put an arrow to a filled.contour plot. I make this: filled.contour(volcano, color = terrain.colors,key.axes=F) arrows(0.95,0,0.95,1,lwd=2) This work, but the problem is that I find the coordinates at random try, for other graphic with other scale is other fight with coordinates. Anybody know a more easy or more generalized way to make this? Somethink like this

Hi, I have a newbie doubt. I try to use metaMDS in R, it is OK, but the stress that I get is 16.32, in other programs stress is showed like 0.173. I don't find a good explanation about this calculations on books, I think that R show stress em a percentage data (0-100) and other software in a proportional data (0-1), it is correct?
