[R] Plot error

[David Meyer]

Pedros:

if you have more than two explanatory variables, the plot.svm() function 
plots a slice out of the input space, i.e., you have to specify the two 
variables that are plot on the x and y axis. The example on the help 
page tells you how:

plot(model, data= dados[,-1], formula=dados[,2]~dados[,3])

should work, choosing all other coordinates except the 2nd and 3rd to be 
0 (default).
