Thanks Uwe.
I definitely want to replace the NaN, unless someone has a better idea.
I have a couple of lists of label-value pairs that come from a randomForest
object.
I plot a series of precision- recall curves (not really curves but
zig-zags) from  x and y lists that came from multiple randomForest runs.
I want to make the comparison between the runs clearer than just plotting
the zig-zags on top of each other, so I tried a curve smoother like lowess.
Lowess doesn't like NaN's.
Replacing the first one in the list with something that is just after it,
lets the smoother work and doesn't really change the comparison between the
runs.
