Hi,
I'm new to R and am learning the ropes of r-help and programming.

Hi:
This worked for me:
t <- 0:100
DBH <- 10:100
TxDBH<-expand.grid(t, DBH)
rm(t, dbh)
time<-TxDBH[,1]
dbh<-TxDBH[,2]
M <- 4000*(1-exp(-time*(1.104-(0.67*0.7)-0.163*log(dbh))^2))
df <- data.frame(time, dbh, M)

But I don't have these vectors x and y, so I have to
create them just to call persp().
And persp also need
Well,
persp(x, y, z) does exactly what you asked for: it plots tha matrix z
along the values given by the vectors x and y.
If you need to calculate z values from x and y using some function foo,
outer(x, y, foo) is typically your friend.

that worked.
however Im trying to get a surface countour like persp() would show.
Since I dont have a matrix data set, I assumed that the wireframe function
would do.
since I get an error using wireframe,

I hope that you actually haven't got any comma to separate the
thousands... it separates fields in a csv files (as the "Comma
Separated Values" name may suggest). If so, get rid of the commas.
