Hello All,

 

I am attempting to use the feather.plot function from the plotrix
package to graph current velocity data as I have speed and direction.  I
let "r" be the first 10 rows of current speed data and "theta" be the
first 10 rows of directional data in radians.  I had tried this with 10
measurements, but keep getting the following error message:

 

 

> feather.plot(r,theta,1:10,yref=0,use.arrows=FALSE, fp.type="m")

 

Error in segments(xpos, yref, xpos + x, y, ...) : invalid third argument

 

My goal was to trouble shoot this smaller data set and see if I could
ramp up to few thousand entries to basically generate a stick plot of
current flow data.  Curious if I was doing anything obviously wrong with
my arguments or if I should be using an entirely different function.

 

 

Thanks for any guidance

Eddie Hughes
