Re: Putting arrows on a scatter graph

Thanks Sanjay. I'm not sure if this will work though. It seems you can only have arrows pointing from the origin or some other point to every other point in the scatter plot. I want an arrow connecting each consecutive point in a particular sequence. I want to be able to specify a "route" around the scatter plot using arrows. Can this be done? data obs;    do i= 1 to 8;       x= round(100* ranuni(123),1);       y= round(100* ranuni(789),1);       output;    end; run; title "Scatter Chart"; proc sgplot data=obs;   vector x=x y=y    / yorigin=32 xorigin=75      datalabel; run; title; ...

Hi RW9 I'm interested in getting the convex hull of a two dimensional polygon - the volume of a polytope is not what I'm looking for. If you download the student university edition of SAS do you get SAS/IML? I know you can do it fairly easily there. Thanks ... View more

I don't have SAS/IML license so I was wondering if there is an algorithm that can be used in SAS/STAT or Base? I don't mind if it's not that efficient or is a bit messy. I want to calculate the convex hull of lots of 8 point polygons simulated as follows:   data obs;    do i= 1 to 8;       x= round(1000* ranuni(123),1);       y= round(1000* ranuni(789),1);       output;    end; run; ...

I have sas/stat and sas foundations but not sas/iml I'm trying to find the area for an irregular polygon. My dataset consists of many points but the example below contains just 8 coordinates. Is there a good algorithm available for doing this? Ideally generalizing it so that it can apply to potentially 100s of points. data coord; input x 1. y 1.; datalines; 14 31 53 87 79 58 47 25 run; ... View more

All except (5,15). When I say edge I mean if you drew a line arounf all the outer points such that there were no points outside the shape the points joining the line would be on the edge. Like an efficient frontier. ... View more

I have a dataset of a 100 randomly generated xy coordinates. I'm trying isolate the points that are on the edge of the area. The definition of this would be: if the xy coordinate has no x value from another point above it or if the xy coordinate has no x value from another point below it or if the xy coordinate has no y value from another point above it or if the xy coordinate has no y value from another point above it I'm looking for a reasonably efficient way of doing this., data obs;    do i= 1 to 100;       x= round(1000* ranuni(123),1);       y= round(1000* ranuni(789),1);       output;    end; run; ...

Thanks Reeza If I chose a START vector, say 750,321 would I need to use arrays to create a table with 18 fields (x1 y1 x2 y2 ... x8 y8 x1y1) which showed every combination of the 8 coordinates conditional on the first number being 750,321. I would then create 19/20th fields with 750,321 in every row. I'm trying to simulate a situation where each coordinate represents a city (so 8 cities) and I want to work out the quickest route if you were to start at 750,321 and visit all cities before returning to 750,321. There are (n-1)!/2 possible routs so 2520. Once I have my table in the above format I will calculate the total distance travelled for each of the 2520 possible routes. The smallest one will be the optimal route. ... View more

I want to be able to simulate 8 random xy coordinates (limiting the max x and y to 1000 each and only allowing integers) and then be able to do the following: Calculate all the distances between all the points. For 8 points there will be n(n-1)/2 distances so 28 distances. I want to calculate the mean and standard deviation of the distances. Calculate the length of every possible route consisting of a path between one of the points (called the start point) and every other point returning to the original point (travelling salesman like situation) and work out the minimum distance. Calculate the distance from the start point to the furthest point from the start point Calculate the distance of the perimeter that consists of the outer points of the shape I know there is a lot here but I'm trying to start off by simulating 8 random numbers. The code below simulates 26 coordinates and the calculates the distance between every point but I want the points to be random. data Obs; do x=0 to 5;    do y=0 to 5;          output;    end; end; run; proc distance data=Obs out=Dist method=Euclid nostd;    var interval(x y); run; Thanks ...

However, the dataset test1 reads in a value for this? The output is given below the code: data test; input flag1 $14.; datalines; dev_cumul1 dev_cumul4 dev_cumul8 dev_cumul16 dev_cumul100 run; data test1; set test; dev_factor = input(flag1,devfactors.); run; flag1 dev_factor dev_cumul1 1.431666437 dev_cumul4 0.99965594 dev_cumul8 1.004175057 dev_cumul16 0.96371087 dev_cumul100 1.02158079 I would have thought the value for dev_cumul100 would be . since it's not on the format table. ...
