   My R is R2.61 + fields 4.1 + spam0.31-1.

   I tried Tps() in fields like
function ()
{
library(fields)
xx <- matrix(c(1,2,3,2,4,5,10,30,20,40,50,90), ncol=2)
print(xx)
yy <- c(5,1,2,3,4,5)
out1 <- Tps(xx,yy, lambda=1000)
print(out1$fitted.values)
print(out1$lambda)
}

The result is:
   [,1] [,2]
[1,]    1   10
[2,]    2   30
[3,]    3   20
[4,]    2   40
[5,]    4   50
[6,]    5   90
  Tps(xx, yy, lambda = 1000) :
  Tps does not currently support the fixed lambda option.
                  See help(Tps) for details

When I replace fields 4.1 with fields 1.72, this error does not
occur. I would appreciate it if some one lets me know why.
