Happy to help, but could you provide a dput() example of your data div1 -- I'm not sure if your table elements are coded as factors or doubles and that can make quite a difference.
Anyways, once you confirm they are doubles, something like this will do it: apply(D, 1, function(x) all(diff(x)>0)) E.g. D <- matrix(c(1,2,3,4,2,5,7,7,9), 3) Michael On Wed, Nov 16, 2011 at 10:49 AM, Mark Carter <mcturra2...@yahoo.co.uk> wrote: > I am scraping data from a web page using XML (excellent package BTW - that's > scraping data the easy way!). > > So far, I've got the code: > > tables <- readHTMLTable(theurl) > rhf <- tables$tabResHistFull > div1 <- rhf[which(rhf$V1=="Div ps"),] > div1 > > which is giving me the result: > V1 V2 V3 V4 V5 V6 V7 V8 V9 V10 V11 > V12 V13 V14 V15 > 15 Div ps p 32.31 35.64 40.17 42.55 45.13 46.36+17.22 51.11 55.72 70.78 > 71.72 76.99 82.20 <NA> > > I don't know a priori how many columns are in the table. > > I want to be able to extract the numbers to the best of my ability, and check > to see if they form a monotonic sequence. > > > How do I do this? > > If I type: > div2 <- div1[is.numeric(div1)] > div2 > I get > data frame with 0 columns and 1 rows > > OTOH, if I type > div2 <- as.numeric(div1) > div2 > I get > [1] 9 4 15 16 18 20 17 21 21 18 24 24 8 8 NA > Huh?? > > What do I need to do?
