I have a function declared thus.
FirstEigenvectorBoundary.Training <-
function(InputFileName='C:/Samples2/PT_Amp.txt',
Header=TRUE, Colour="red")
Inside the function, I have the following call
out<-list(x=Eigenvectors[2:(NumMetricsSelected+1),1],
y=-0.8, z=NumMetricsSelected);
NumMetricsSelected has the value 2 and Eigenvectors
has the following form
[,1] [,2] [,3]
[1,] 0.6404630 -0.2153989 0.7371638
[2,] -0.6081319 0.4439621 0.6580830
[3,] 0.4690231 0.8697706 -0.1533503
When I do it manually at the console, I get the
correct result. I.e.> out
$x
[1] -0.6081319 0.4690231
$y
[1] -0.8
$z
[1] 2
However, when I call the function like this> Training<-FirstEigenvectorBoundary.Training()
I get>Training
$x
[1] 0.658083
$y
[1] -0.8
$z
[1] 2
That is, the $x element has only one value (instead of
2) and it is from the wrong part of the matrix.
Can anyone see what I am doing wrong?
Thanks very much,
Peter.
My solution when I run into mysteries like this is to put browser() in the function just before or after the line of interest. The magnitude and direction of my stupidity usually become clear quickly.
