The translation process occurs in several steps. If the input to the yacas function is an expression then it is translated to a valid yacas character string (otherwise, it is sent to yacas unprocessed). Yacas then processes the string and if retclass="expression" it is translated back to an R expression (otherwise it is sent back unprocessed). Currently supported translations are:

CONSTANTS
R		yacas
=		=====
pi		Pi

OPERATORS
R		yacas
=		=====
7 %% 3		Mod(7, 3)
7 %/% 3		Div(7, 3)

FUNCTIONS
R		yacas
=		=====
sin(x)		Sin(x)
cos(x)		Cos(x)
tan(x)		Tan(x)
asin(x)		ArcSin(x)
acos(x)		ArcCos(x)
atan(x)		ArcTan(x)
exp(x)		Exp(x)
sqrt(x)		Sqrt(x)
log(x)		Ln(x)
choose(n, k)		Bin(n, k)
gamma(x)		Gamma(x)
deriv(sin, x)		Deriv(x)Sin(x)
integrate(f, a, b)		Integrate(x, a, b)f(x)
list()		List()
factorial(n)		n!

Note the Limit example in demo(Ryacas) for adding translations on the fly.
