Differential Equations Using R?

To whom it may concern,
I am a student at Macaleste College, and next semester Macalester
is going to offer a course for CellBio that is mainly statistically based.
For the most part the students will be using R for analysis. The problem is
there will be some simple differential equations for the students to solve.
The committee that in charge of the classes corriculam would like only to
have to use one software package "R" for the entire corse. Thus the
students will not have to learn another platform in order to solve
differential equations. I have been nominated to find out if there exists
such a program for "R". Hence the question: Does there exist a program,
which has been written for R, where differential equations can be solved
numerically? If there is please contact me at your convience on where I may
find this program. If there is not such a program would it be simpler to
write such a program or to just learn how to use MatLab or another math
program? Your input would be greatly appreciated. Thank you all for your
time.
Have you looked at the odesolve package on CRAN?
