Strategy for mapping a function of several inputs and outputs using R -

-

i want plot function of many inputs , outputs using r study how outputs depend on inputs. function economic model but, simple example, write function as

f <- function(x, y, z) {   = x * y^2   return (data.frame(a,                       b = x + y + z,                      c = sqrt(a))) }

(i used data.frame return several outputs open other suggestions - perhaps should taking data.frame input well?)

now, want plot a function of x when y , z 1, likewise plot c function of y , x , z set 2.

i've created components , helper methods using c++ , qt used in qml gui. of methods calculate gui elements (size, transformations, scene graph items creation). target arm 32 bit using opengl / eglfs render output. opengl using float , qml using real (defined double ). what should use in c++ do not lose precision? if use qreal ( double ) shouldn't lose precision. if git grep float in qtbase.git , can find out bit more: dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0-* important behavior changes * dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0- dist/changes-5.2.0- - qt compiled qreal typedef'ed double on dist/changes-5.2.0: platforms. qreal float on arm chipsets before. guarantees more dist/changes-5.2.0- consistent behavior between platforms qt supports, binary dist/chan...
