Sorry if this is a silly question. I'm trying to extract all elements
of a dataframe at a particular row.
How about
df[12, ]
to get row number 12?
I can find no mention of this in any documentation
You must have different documentation than me
Subsetting is described on the first

If you're having so much trouble, perhaps it's because you want to get a
vector result? This requires a little more, and if so, perhaps one of the
following provides what you are looking for:
x - data.frame(a=1:3,b=4:6)

x[2,]
a b
2 2 5
# row as a list
x[2,,drop=T]
