Hello all, I have another question. I'm working with the following dataset: plot plant leaf_number sen_score plot_lai plant_lai lai_score leaf_num 104 5 1 90 104 1 82 1 104 5 2 90 104 1 167 2 104 5 3 95 104 1 248 3 104 5 4 100 104 1 343 4 104 6 1 95 104 1 377 5 104 6 2 85 104 1 372 6 104 6 3 90 104 1 335 7 104 6 4 90 104 1 221 8 105 5 1 90 104 1 162 9 105 5 2 95 104 2 145 1 105 5 3 100 104 2 235 2 105 5 4 100 104 2 310 3 105 6 1 70 104 2 393 4 105 6 2 80 104 2 455 5 105 6 3 90 104 2 472 6 105 6 4 80 104 2 445 7 106 5 1 100 104 2 330 8 106 5 2 90 104 2 292 9 106 5 3 100 105 1 64 1 106 5 4 100 105 1 139 2 106 5 10 0 105 1 211 3 106 6 1 100 105 1 296 4 106 6 2 30 105 1 348 5 106 6 3 100 105 1 392 6 106 6 4 40 105 1 405 7 108 5 1 100 105 1 379 8 108 5 2 100 105 1 278 9 108 5 3 100 105 2 64 1 108 5 4 100 105 2 209 2 (Note: 'plant' and 'leaf' column should be separated. '51' means plant 5, leaf 1). This dataset shows two datasets: The left 4 columns are of one measurement (leaf senescence), and the right 4 columns are of another (leaf area index). I have a large amount of plots, and several plants, more than what is listed. I need to sort both datasets (senescence and leaf area index) so that each plot has the same number of leaves. This is hard because sometimes plots in the 'senescence' dataset have more leaves, and sometimes plots in the 'leaf area index'. Is there a way to sort both datasets so that this requirement is met? Like I said, there is no way to tell which dataset has the plot with the minimum amount of leaves; it can be either one in any case. Any help would be appreciated!

Read the posting guide, please, paying particular attention to how to provide reproducible data, e.g. via ?dput. You are much more likely to get useful help if you do what it recommends and provide data for people to work with. You also should provide code showing us what you tried. You appear not to have done much homework of your own -- have you gone through some R tutorials, for example? Which ones?

Hi
Could you show what is your intention with your data? What do you mean by sort
data to have the same number of leaves? Do you want to trim excessive rows in
both data.frames to meet such condition?
I would suggest using merge.
merge(test1, test2, by.x=c("plot", "plant"),
by.y=c("plot_lai", "plant_lai"), all=TRUE)
which gives you one data.frame with rows corresponding to each plot and line
After that you could remove all rows having NA in respective columns, which
ensures that there is same number of leaves in each column.
Cheers
Petr
