>From ?xtable:

digits: Numeric vector of length equal to the number of columns of
          the resulting table indicating the number of digits to
          display in the corresponding columns. Since the row names are
          printed in the first column, the length of `align' is one
          greater than `ncol(x)' if `x' is a `data.frame'. Default
          depends of class of `x'.


For example

> library(xtable)
> mydf<-data.frame(id=1:6, x1=rnorm(6), x2=rnorm(6))
> xtable(mydf, digits=c(0, 0, 3, 5))
