[R] error using boxplot.stats (but boxplot works¿?)

The answer to this may be obvious, but it's got me floored.
I'm unable to get boxplot.stats to work for me!
My session looks something like this:
> ia=read.table('/tmp/prueba.csv', header=TRUE, sep=",")
Error in sort (na.last, decreasing, ...) :
argument 1 is not a vector
In addition: Warning messages:
1: is.na() applied to non-(list or vector) in: is.na(x)
2: is.na() applied to non-(list or vector) in: is.na(x)
3: is.na() applied to non-(list or vector) in: FUN(X[], ...)
[the error message in R 2.3.1 is slightly different: it says it is not
atomic and shows only the 1st two warning messages]
However, boxplot(X8weeks~Orden) prints the boxplot properly (no error messages, data accurately represented).
"X8weeks" has no NA's
So, the question is: how can I access the data used to generate the boxplot (and why does boxplot.stats fail)?
