Hi,
I'm trying to plot an equation in two variables to get a feel
for sensitivity to its parameters. I've run expand.grid to get made-up
vectors of the combinations of the two independent variables, and am trying
to plot the output of the dependent, M, against both the dependent in a 3d
space.

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.

Hello,
say I have a 2D-matrix (indexed by x and y), which contains
z values, which I want to plot over x-y.
Either dotted, or if possible as a landscape.
I tried around with persp and plot3d (from rgl)
and persp3d (from rgl).
I sometimes get something that looks good and a while later, when

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.

I am trying to dp a 3d plot.
I tried persp but my data is not a matrix.
the 3dplot function returns this error, (list) object cannot be coerced to
'double'
heres my code,
td<-read.csv("td.csv", header=TRUE)
price<-read.csv("price.csv", header=TRUE)
contractdate<-read.csv("contractdate.csv"
