Plot a single dimensional Function
plotSingleDimFunction(evalFun, lower, upper, target)function to be plotted. The function should either be able to take two vectors or one matrix specifying sample locations. i.e. z=f(X) or z=f(x2,x1) where Z is a two column matrix containing the sample locations x1 and x2.
boundary for x1 and x2 (defaults to c(0,0)).
boundary (defaults to c(1,1)).
String, which type of uncertainty estimation should be plotted? default: NULL - no estimation plotted. 's' standard estimation. 'sLinear' linearly adapted estimation.
