Dear R users,
I was trying to do a 3d scatterplot for the following set of datas:
"obj" "time" "X" "Y"
"1" "yellow" "333" "388.7" "492.3"
"2" "yellow" "567" "388.7" "492.3"
"3" "green" "621" "135.5" "371.7"
"4" "green" "1039" "135.5" "371.7"
"5" "red" "1373" "744.1" "205.0"
"6" "red" "1763" "744.1" "205.0"
The points should be drew in the plot taking information of "time",
"X" and "Y". The colors of these points should be assigned according
to the information contained in variable "obj".
What I did but it didn't work out is:
1) Plotting only one set of points (the green one)
s3d<-scatterplot3d(greenpts[,3],greenpts[,2],greenpts[,4],type="p",scale.y=4,
angle=10, color="green")
and try to overlay the others (as you normally would do with "plot"):
s3d$points3d(redpts[,3],redpts[,2],redpts[,4],col="red",type="o")
s3d$points3d(yellowpts[,3],yellowpts[,2],yellowpts[,4], col="yellow",type="o")
s3d$points3d(bluepts[,3],bluepts[,2],bluepts[,4],col="blue",type="o")
s3d$points3d(pinkpts[,3],pinkpts[,2],pinkpts[,4],col="pink",type="o")
R has plotted only the first set and wasn't able to overlay other points.
2) I have generated a "for" loop that should have taken points
information ,arranged into a list object, plotting them one by one.
- listpoints = list(X,Y,time)
-color<-rep("black",26) ##solution found in one of the discussion
around scatterplot
color[mat1$obj=="green"]<-"green"
color[mat1$obj=="yellow"]<-"yellow"
color[mat1$obj=="red"]<-"red"
color[mat1$obj=="pink"]<-"pink"
color[mat1$obj=="blue"]<-"blue"
for (i in 1:26)
points3d(listpoints[i],type=1, col=color[i])
Also this way didn't work out. Do you have any solution?
Many thanks
Moreno
P.S. I have tried also points3d(rgl) trying to follow an explanation
given in the forum but i haven't understood how to set the function.
