[R] lda

[Martin Willett]

I am trying to write the following code in R.  The code works in S+ and i 
am trying to do the program in R.

x=discrim(admit~gpa+gmat,prior=c("uniform"),data=data.mm)

i wrote the following in R:

x=lda(admit~gpa+gmat,data=data.mm)

i could not figure out how to write prior=c("uniform") in R.  I would get 
an error every time.  I think that it has something to do 
with "uniform".  Do you know what i use instead of "uniform" for R?  I am 
trying to do a uniform distribution.
Thank you.
