yacmode {Ryacas}R Documentation

yacmode interface

Description

Interactive interface to the yacas

Usage

yacmode()

Details

The user types valid yacas input and presses return. Type 'quit' to return to R prompt.

Value

Output of yacas is returned.

Note

Note that command recall will recall previous R commands, not previous yacas input. Yacas is given a limited amount of time to complete, otherwise '[1] CommandLine(1) : User interrupted calculation' is returned. E.g. Taylor(x,0,5) 1/(1+x) will work, but Taylor(x,0,12) 1/(1+x) is likely to take too long.
