Sorry if this is a silly question. I'm trying to extract all elements of a dataframe at a particular row. I can find no mention of this in any documentation and it may be naivety of dataframe on my part as I'm very green at this. Thankyou,
Mark

dat <- data.frame(var1 = c(1:10), var2 = c(31:40), var3 = c(6:15))
dat[1, ] #extract 1st row
dat[1:4, ] #extract rows 1 through 4
dat[c(1,3,5,7,9), ] #extract named non-consecutive rows
dat[ ,1] # extract 1st column
... etc
It's in 'An Introduction to R' that should have come with your distribution, or in the manuals section of the r website:
