Hi I am using R to implement a multidimensional algorithm which maps places based on the distances between each other. This is presented really well in Rggobi.
However, for each place plotted, I have another numerical statistic between 0 and 1 which I would like to represent by colouring the points in Rgobbi. However I do not know how to do this. The file I am using is called places.txt and has the following contents: Chelt Exeter London Birm Chelt 0 118 96 50 Exeter 118 0 118 163 London 96 118 0 118 Birm 50 163 118 0 To plot these, the R code is as follows: library(rggobi) Places<-read.table("C:\\places.txt") Places.location <- cmdscale(Places, k=2) round(Places.location,0) g<-ggobi(Places.location) Now, for each point plotted I want to assign a colour to it based on the statistic in a file called PlacesStats.txt which currently has the following format: 0.1 0.3 0.4 0.5 With the values in order of the names of the places given above so that: 0.1 is assigned to Chelt 0.3 is assigned to Exeter 0.4 is assigned to London 0.7 is assigned to Birm Ideally, I want a gradient of two colours so that say, 0 = blue and 1 = red and values between are a mixture. Any ideas on how I could do this? Would I need to change the PlacesStats.txt file so that is reads: Chelt 0.1 Exeter 0.3 London 0.4 Birm 0.7 for example? I would be very grateful if anybody could help.
