Dear R users,
I have been using rsympy to solve a set of simultaneous equations from
R. There are two solutions for the variable I'm interested in, xx[0] and
xx[1], which are in terms of symbols called lam and conc. I'd like to
pick out the one which is positive at (lam=0, conc=0) and call it mysol.
In python I could write:
if (xx[0].subs(lam,0)).subs(conc,0)>0:
mysol=xx[0]
else:
mysol=xx[1]
but I'm not sure how to do it from R via rsympy. The various
combinations of \t and \n characters and spaces I've tried haven't
worked, and I haven't been able to find any examples online or in the
help file.
Do you know whether it is possible to enter multi-line input using
rsympy, and if so how?
Thank you in advance,
Joanna
