[R] Hmisc + summarize + quantile: Why only quantiles for first variable in data frame?

Hi,
I'm working on a data set that contains a couple of factors and a
number of dependent variables. From all of these dependent variables
I would like to calculate mean, standard deviation and quantiles.
With the function FUN I get all the means and stdev that I want but
quantiles are only calculated for the first of the dependent
variables (column 8 in the summarize command). What do I have to do
differently in order to get all the quantiles that I want?
Thanks,
Kim
sgldm2 <- read.table("E:/analysistemp/060412_test_data2.txt", header=T)
attach(sgldm2)
names(sgldm2)
FUN <- function(x)c(Mean=mean(x,na.rm=TRUE),
STDEV=sd(x,na.rm=TRUE), Quantile=quantile(x, probs=
c(0.25,0.50,0.75),na.rm=TRUE))
ordering <- llist(time_h_f, Distance_f)
resALL <- summarize(sgldm2[,8:10], ordering, FUN)
