fields package question
Since you don't provide lambda, rh or qext it is impossible to reproduce what you are seeing. Also note that in this mailing list HTML formatted emails are not passed along.

Hello,
I used commands below to obtain a surface, can plot it and all looks as
expected.
How do I evaluate values at new point. I tried as below but that produces
errors.
Thanks for suggestions/help.
x <- log(lambda)
y <- rh
z <- qext[,,2]
grid.l <- list(abcissa=x,ordinate=y)
xg <- make.surface.grid(grid.l)
out.p <- as.surface(xg,z)
plot.surface(out.p,type="p")
tried:
grid_new.l <- list(abcissa=c(-15.0,-10.),ordinate=y)
xg_new <- make.surface.grid(grid_new.l)
out_new.p <- predict.surface(out.p,xg_new)
results in this prompt:
predict.surface is now the function predictSurface>
