R help - Mar 2010 - package earth - forward pass: out of memory error, how to resolve this?

Hello,

while using earth function, I'm getting the out of memory error:
the dataset is too small(dimension is displayed in code).
how to resole this error?
> tr.sub1 <- sample(1:nrow(HCMauto), .8 * nrow(HCMauto))
> tst.sub1 <- (1:nrow(HCMauto))[-tr.sub1]
> HCMm1 <- earth(V1 ~ ., data = HCMauto[tr.sub1, ])
Error in forward.pass(x, y, standardized.weights, scale.y, trace, penalty,
:
  Out of memory (could not allocate 2017.29 MBytes)
> dim(HCMauto)
[1] 85 10
> dim(HCMauto[tr.sub1,])
[1] 68 10


Thanks.
