[R] ggplot2 barplot: extra markers in graph

Dear List, (self-contained example + version info at the bottom) I'm having trouble producing a barplot using the functions in ggplot2. When I use the position=dodge option, the bars are plotted but also a number of spurious markers. More specifically, a number of black dots are plotted in

Re: [R] Kruskal's MDS results

A few people suggested taking a look at Ripley's book MASS. I know the formula listed there. The point is that the manual for the isoMDS function says it's stress output is in percent. Does this mean, the stress reported by isoMDS is just the stress value in MASS (which ranges from 0 to 1)

Re: [R] Kruskal's MDS results

Non-metric Multidimensional Scaling algorithm (isoMDS, MASS package). The 'goodness of fit' is reported as The final stress achieved (in percent). What does this mean exactly? I've tried to google for an answer but I've not come up with a definitive answer. Regards, Dieter -- Dieter Vanderelst

Dear List, I'm using interp() to prepare 3d data for plotting with the contour() function. If have x,y and z data. All are arrays. X and Y are sampled in an orderly fashion on a grid (a circular sub-area of a grid - see plot). I'm trying to use interp() to get x and y arrays and a z matrix
