select dataframe records

Hi,

I'm reading some data from a file. The code below plots the all records in a barplot. How can I plot only records 5 to 10?
By indexing?
Please read the psoting guide and the docs.
chldata <- read.table("test3.txt",header=TRUE)
barplot(rev(chldata$chlorophyll),horiz=TRUE,names.arg=rev(chldata$depth))
with(chldata[5:10,],
     barplot(rev(chlorophyll), horiz=TRUE, names.arg=rev(depth))

Uwe Ligges
Thanks in advance,
Pieter
